Innovations Offering Explosion Protection

Posted on by David Priestman

Linde Material Handling will be presenting innovations from its explosion protection range at ACHEMA. The three electric pallet truck models of the Linde T16 EX to T20 EX series feature compact dimensions and are designed for transporting loads in the tightest of spaces. Another new product on offer for explosion-protected counterbalanced trucks is the artificial intelligence (AI)-based “Reverse Assist Camera” system. It identifies people to the rear of the truck and alerts drivers of potential collisions, providing targeted and gradual warnings.

“Each new explosion-protected truck model from Linde MH is developed from the outset together with the pilot series for the standard version. This allows customers in the chemical, pharmaceutical, cosmetics and food industries to benefit from the technical refinements at an early stage,” explains Elke Karnarski, Product Manager EX-Proof Trucks & Safety Solutions at Linde Material Handling.

Explosion protected equipment

The introduction of the Linde T16 EX to T20 EX series marks the debut of new compact pedestrian pallet trucks on the market. Featuring a robust chassis and reinforced forks, they are designed for loads of up to two tons. The models are available in the 2G/2D and 3G/3D equipment categories for ATEX zones 1/21 and 2/22. The narrow design, tight turning radius and intuitive steering and controls make the trucks quick and easy to maneuver in confined spaces. Explosion protection measures include ignition protection against electrical and mechanical sparks, continuous temperature monitoring of relevant components and precautions to prevent electrostatic charging.

The low-mounted tiller ensures ample safety distance from the operator, while the active foot protection guard and the deep-drawn chassis provide additional protection against injury. Information on important vehicle parameters – such as the battery charge status and the next required service check – is available via the centrally positioned multifunctional display. The Linde EX-Monitoring app displays safety-related readings and provides operators and fleet managers with specific instructions if necessary. At the same time, the application enables preventive, bundled maintenance measures, thus ensuring high operational availability of the vehicles.

AI-based person detection for intelligent accident prevention

With the Linde Reverse Assist Camera, an innovative assistance system is now becoming suitable for use in truck categories 2G/2D (ATEX zone 1/21) and 3G/3D (ATEX zone 2/22). The camera, which was developed using artificial intelligence, has “learned” to distinguish between people and objects. If a person is detected, it emits visual and acoustic warnings, depending on the distance. In addition, an automatic reduction in driving speed can be activated to further minimize the risk of accidents. The display and camera are housed in pressure-resistant enclosures to allow for use in ATEX zone 1/21.

“The demand for safety assistance systems that can be used with explosion-protected industrial trucks has increased noticeably in recent years,” says Product Manager Elke Karnarski. “This is not least due to the fact that in many cases they are part of a mixed fleet with standard trucks. Existing assistance systems should accordingly be installed across all vehicles in order to achieve a uniformly high level of safety,” she explains.

The Linde Safety Guard is certified for ATEX zone 2/22. Equipped with so-called “Truck Units”, the vehicles communicate via signals in the UWB area through racks and can locate each other. If the distance falls below a defined level, the system reduces the driving speed. This technology can also be used to regulate speed zones for entire halls or specific sections using so-called “zone markers”. In addition, the Linde Safety Guard acts as a “gatekeeper”, allowing only EX-protected vehicles to enter the ATEX zones.

Customized solutions for special application scenarios

Customized solutions developed for individual applications are not uncommon for explosion-protected industrial trucks. One example is the “drum cradle”. This specially designed pallet stacker with additional attachments on display at the Linde booth can transport 300-liter drums as well as pick up open drums, tip them and empty the liquid inside. The integrated scales are accurate to 500 grams. Operation of the drum clamping functions is carried out either via a control lever or remotely for optimal visibility during the tipping process.

Automation from Simple to Complex

Posted on by David Priestman

Companies aiming to improve their competitiveness through more highly automated intralogistics will find everything they need from a single source at Linde Material Handling (MH): a broad portfolio of automated guided vehicles (AGVs) and mobile robots (AMRs), suitable for projects ranging from small to large and simple to complex. Additionally, they will have at their disposal a team of experts that has grown considerably in recent years and serves to ensure professional planning and implementation. With the Linde L-MATIC HD k automated pallet stacker, the company is launching an additional model with a lift height of up to 3.8 meters for the substantial field of horizontal transportation. The series truck offers corresponding delivery times, faster commissioning thanks to new software and simplified service. Furthermore, the near-series concept study of the Linde L-MATIC C automatic compact stacker will make its debut at the Linde MH booth at LogiMAT 2024 as part of an engaging live case presentation. Thanks to its compact dimensions, this truck featuring an integrated lithium-ion battery is particularly suitable for applications in confined spaces and for small and large vehicle fleets. It is scheduled to go on sale at the end of the year.

“The automation of material flow processes is now possible in almost all warehouse and production areas,” says Louis Vieira, Head of Sales Automation & Intralogistics Germany at Linde Material Handling, encouraging all logistics managers to get to grips with the subject. In his opinion, processes with a high degree of standardization are especially suited for this purpose. These include, for example, the low-level transport of goods between defined transfer stations, for which AMRs with transport platforms are recommended. The same applies to replenishment in high-bay warehouses using automated reach trucks or the picking of pallets in racks up to 16 meters high. “However, the largest range of applications for autonomous or automated industrial trucks is unquestionably found in the extremely versatile pallet stackers,” says Louis Vieira. The vehicles can be used for distance transport and are also capable of lifting loads to medium heights. They can be used for tasks ranging from production supply and the collection of finished products to transport between incoming goods and staging areas, the supply of goods for shipping and the transfer of load at the interface with VNA forklifts.

New models for a growing variety of applications

With the Linde L-MATIC HD k, another truck model for these and other applications is now being launched on the market. The automated pallet stacker can move goods weighing up to 1.6 tons between conveyor belts, frames, marked floor areas or rack locations and store and retrieve them at heights of up to 3.8 meters. The industrial truck features a range of 360° safety scanners and load sensors and can travel at speeds of up to 7.2 km/h. It already meets the technical safety requirements of the European ISO 3691-4 standard for driverless industrial trucks. The pallet stacker can be optionally equipped with features such as the Linde BlueSpot, warning lights, a second load sensor and additional obstacle detection. The Linde L-MATIC HD k draws its energy from either a lead-acid or lithium-ion battery; suitable chargers are supplied ex works, as is the truck itself. Various options are available for (intermediate) charging, both manually and fully automatic. In the latter case, the vehicle automatically connects to a charging station, allowing the maximum operating period of approximately 18 hours to be extended to 24/7 operation. Two different commissioning software solutions ensure fast implementation of the vehicles. Another special feature is that the service is carried out by trained technicians, and the short repair and maintenance times ensure greater operational availability.

The fully automated Linde L-MATIC C pallet stacker with a load capacity of 1.2 tons, which will be presented as a near-series concept study at the intralogistics trade show in Stuttgart, is recommended for brownfield automation due to its short, narrow design. Especially in warehouse and production layouts that have grown continuously over the years, space is often tight or aisles are narrow. Measuring 1,785 millimeters in length and 840 millimeters in width, this pallet truck featuring a permanently installed lithium-ion battery is recommended in such cases as a flexible, scalable option for pallet transport that was previously carried out using larger, manually operated industrial trucks. This vehicle also comes with new software for commissioning. Instead of users having to program it themselves, the project logic is configured via a simple, clear user interface.

However, companies should not focus solely on the topic of automation, says Sales Manager Vieira. The digitalization of data, documents and processes is just as important. This can be achieved, for example, with the Linde Warehouse Navigator, which consists of a warehouse management, order picking and forklift guidance system. This software solution enables all orders, stocks and goods movements in the warehouse to be controlled, monitored and documented without the need for paperwork. 3D visualization provides an overview of the current occupancy for the entire warehouse and truck drivers are shown the fastest route to their destination. At the same time, the software documents all load carrier movements through changing storage locations.

Intralogistics Performance is Paramount

Posted on by David Priestman

Automation solutions offer enormous potential when it comes to internal material flow. At this year’s LogiMAT trade show in Stuttgart, Germany, Linde Material Handling (MH) will be demonstrating the options available to small, medium-sized and large companies and showing how a wide range of project requirements can be successfully implemented. Energy, Safety and Warehouse Intelligence will be further key topics in focus at the centrally located exhibition booth in Hall 10. Offering the broadest portfolio of energy and safety options for industrial trucks and leading technical material flow solutions, the intralogistics specialist supports its customers on their way to greater efficiency, sustainability and performance.

Occupying more than 500 square meters, Linde MH’s main booth in Hall 10 (Booth B21 and B17) highlights current trends in intralogistics: Automation, Energy, Safety and Warehouse Intelligence. On display will be corresponding products and solutions which are designed to optimize the internal material flow. A live demonstration will showcase flexible and scalable automation solutions involving automated guided vehicles (AGVs) and autonomous mobile robots (AMRs). Just a few meters away from the exhibition stand, in the loading yard between Halls 8 and 10, visitors can test forklifts for themselves or get an up-close look during vehicle demonstrations. Examples include various reversing assistance systems, such as the AI-based Reverse Assist Camera, that alert industrial truck drivers to people in the vicinity behind them. Additional exhibition space that offers hands-on experience with various vehicle models is located in the outdoor area between Halls 9 and 10.

“The Linde brand represents top performance in goods handling. This is achieved through innovative products and solutions, a high level of user-friendliness, a wide range of active and passive safety and assistance systems, customized individual solutions and the comprehensive consulting expertise of our sales organization. Our products and solutions ensure maximum productivity even under the most demanding operating conditions, such as those found in the beverage, paper, wood, food and chemical industries,” says Torsten Rochelmeyer, Senior Director Strategy & Solution Portfolio at Linde MH.

At LogiMAT 2024, Linde MH will showcase its expertise as a competent partner for the automation of material flow processes. “Together with our network partners, we have successfully planned and implemented hundreds of projects in recent years,” reports Rochelmeyer, referring to the sales organization’s extensive expertise and experience gained in small and large projects alike. Alongside this, standardized solution packages are available for simple transport tasks. “This allows existing brownfield processes in particular to be automated more quickly,” says the Linde trade show manager. The company’s automation experts can resort to a large product portfolio when it comes to implementing projects: The range extends from AMRs such as the Linde C-MATIC and the Linde C-MATIC HP, to automated pallet stackers (Linde L-MATIC) and tow tractors (Linde P-MATIC) all the way to reach trucks (Linde R-MATIC) and VNA trucks (Linde K-MATIC). Where complex automated material flow systems are required, colleagues from the Group’s sister company Dematic will be involved, whose booth in Hall 10 is directly adjacent to the Linde MH area.

The Energy area of the exhibition covers the company’s broad spectrum of available energy types, with a focus on the X-series electric counterbalanced trucks with lithium-ion batteries. They are just as powerful, robust and ergonomic as ICE-powered trucks, but are emission-free and potentially CO2-neutral in operation. However, diesel, LPG, CNG, lead-acid batteries, fuel cells and HVO (Hydrotreated Vegetable Oil) are also available as power options. “Visitors who want to find out about suitable energy systems for their current or future fleet will be offered software-assisted advice that provides an initial assessment based on the requirements, general conditions and customer-specific situation. This can be followed by further analysis within the company,” explains Rochelmeyer. Another focus will be on the Linde connect fleet management system. In addition to access control, damage monitoring, vehicle and driver management, fleet usage analysis and predictive maintenance, the Linde connect:charger software module provides intelligent control of battery chargers, helping to avoid expensive power peaks.

In general, the following applies to all warehouse activities: The safer the internal material flow, the higher the productivity and thus the contribution to the company’s success. Using a reach truck equipped with extensive safety features, Linde MH demonstrates how fleet operators can ensure smooth processes and protect their employees. The features range from a large number of driver assistance systems such as the Linde Safety Guard for the mutual warning of pedestrians and drivers and the Rack Protection Sensor for avoiding collisions with racks and goods to various lighting solutions and protection systems like the Dynamic Mast Control system for reducing mast vibration.

In the Warehouse Intelligence area, guests can learn how to make their warehouse even more efficient and dynamic with the help of modular software solutions. An application consisting of a warehouse management system, a forklift guidance system and a warehouse control system provides real-time visualization of the warehouse through a three-dimensional view and shows the driver the fastest route to the destination. In the process, it automatically tracks the movements of the load carriers across changing storage locations, which ensures a high degree of transparency. The software is also capable of integrating and controlling various automated systems such as AGVs and shuttles.

Autonomous Outdoor Forklift Operation

Posted on by David Priestman

Intralogistics specialist Linde Material Handling and the Aschaffenburg University of Applied Sciences (UAS) presented the results of the research project “KAnIS – Cooperative Autonomous Intralogistics Systems” with live demonstrations on the test site at the Linde plant in Aschaffenburg on December 5, 2023. In several subprojects, solutions were developed for the demanding applications of autonomous counterbalanced forklifts, which transport loads both indoors and outdoors. One focus was on the cooperative behaviour of these vehicles that exchange information in real time via a 5G network and an edge server and can warn each other of obstacles. The project, which ran for almost four years, was funded with approximately 2.8 million euros as part of the Free State of Bavaria’s ‘Information and Communication Technology’ R&D program.

“Autonomous vehicles will gradually take over more and more transport tasks,” asserts Stefan Prokosch, initiator of the KAnIS project at Linde MH. As a technology leader in the industry, the intralogistics specialist wants to make the benefits of autonomous vehicles available to customers who use counterbalanced forklifts to transport goods or load and unload heavy trucks. “However, the requirements for forklifts operating in outdoor areas are much higher than those for purely indoor vehicles. These include the ability to operate on inclines and gradients, the presence of a significantly higher volume of people and traffic and different weather influences and temperature conditions that need to be taken into account,” Prokosch explains. “Thanks to the joint research work with Aschaffenburg UAS, we have been able to develop viable solutions for these complex requirements. Once the project is completed, these findings will form an essential basis for further development projects.”

The overall goal of the project was to investigate how the cooperative behaviour of networked, autonomous vehicles can improve operational reliability and handling performance. To solve this broad task, several subprojects were formed to address vehicle location, regulation and control as well as forklift cooperation, load carrier recognition, the impact of weather influences, predictive maintenance, route optimization and automatic load management.

“For the university, the KAnIS project was a very complex, interdisciplinary research project. Ten professors and numerous research assistants and students were involved,” summarized Prof. Dr. Hans-Georg Stark, Project Manager KAnIS, Faculty of Engineering at Aschaffenburg UAS, during the event. “Both project partners have benefited greatly from the intensive exchange between Aschaffenburg UAS’s scientific research activities and Linde MH’s many years of expertise in vehicle development.”

Practice-oriented test scenarios under realistic conditions

Four Linde E20, E25 and E30 electric counterbalanced trucks with a load capacity of 2.0 to 3.0 tons were automated and equipped with electrohydraulic steering (Linde Steer Control), the Linde Safety Pilot assistance system with electronic load diagram and an integrated fork positioner. “The practical implementation of the research results was an important aspect for both Linde MH and Aschaffenburg UAS,” emphasized Mark Hanke, a Head of Department in Pre-Development at Linde MH. Starting next year, the vehicles are to be further developed and tested so that they can perform four specific material handling tasks in the future. These include the transport of wire mesh crates and of pallets containing batteries, and the relocation of vehicle frames and overhead guards, which have to be transported on special load carriers from pre-assembly to the main assembly lines.

The first two applications are purely outdoor operations, while the other two require the trucks to travel both inside and between the halls. Gradients of 8 percent have to be overcome, and there are also other AGVs and manually operated vehicles in the halls. To ensure that the four KAnIS forklifts can reliably pick up the pallets, wire mesh crates and metal frames even if they are not precisely aligned with the floor, they are equipped with a mobile camera mounted between the forks. It measures the pockets of the load carrier so that the forks can be positioned correctly via the side shift. The designs of the vehicle frame, battery door and counterweight were adapted as well. “Our goal was to integrate the safety scanners, cameras and sensors as much as possible into the vehicle contour so that the truck’s dimensions remain as close as possible to the standard version,” says Hanke. Indoors, the vehicles locate themselves via laser scanners, outdoors, they use differential GPS (Global Positioning System), a method of increasing the accuracy of GPS. In addition, they feature additional local sensors for the switch from indoor to outdoor areas. Unlike their manually operated counterparts, the automated forklifts always travel in reverse on their defined routes to prevent the load from slipping off the forks in the event of an emergency stop.

Real-time communication with trucks and infrastructure

A particular focus of the research project was on the automated forklifts’ perception of their surroundings in order to ensure their reliable interaction with other road users. For this purpose, the vehicles are equipped with 3D scanners and HD cameras in addition to the sensors of the personal protection system. The camera data forms the basis for detecting and classifying objects with the help of AI algorithms and then locating them in order to adjust the vehicle’s speed and slow it down to a standstill. But that’s not all. Another key issue focused on critical situations that arise when people are in concealed areas that cannot be detected by the forklift’s sensors and approach the vehicle’s path of travel. This is where cooperation between the forklift trucks comes into play, because if another forklift is in the vicinity, it can provide the relevant information. However, this requires real-time transmission of the perception data. To achieve these low latencies, Linde has set up a private 5G network at the Aschaffenburg plant. The perception data is transmitted from the forklifts to an edge server, which uses the locally detected objects to create a global list of all detected objects and sends it back to the forklifts.

The test was conducted using a crash-test dummy that suddenly emerges from behind a wall and runs into the forklift’s path. Without cooperative behaviour, the automated forklift truck cannot stop in time and runs into the dummy. However, if it receives real-time information from a nearby forklift, it can anticipate the dangerous situation in advance and brake in time. Since it is not always possible to assume that a second forklift is nearby, eight stationary 3D laser scanners were installed at intersections and gateways along the routes that the KAnIS forklift trucks will travel in the future. The local object lists of the stationary laser scanners are also merged on the edge server and the information is made available to all vehicles.

“Fast wireless networks are the prerequisite for autonomous forklifts to be able to act cooperatively in outdoor areas and react to unforeseen traffic situations in real time,” emphasized Prof. Dr. Klaus Zindler, Vice President for Research and Transfer at Aschaffenburg UAS, at the event. “Our goal is to develop general standards and algorithms using AI methods, which can then be flexibly applied to different vehicles and applications and continue to learn.”

Cleaning system for sensors, battery charging by robot

Another work package looked at how to clean the near-ground optical sensors when they become dirty from water splashes in the rain or wet road surfaces. This is critical because if reliable object detection is no longer possible, the operator protection system will automatically bring the truck safely to a stop. To prevent this, the project team developed a cleaning system that uses compressed air to blow off any dirty water droplets that may have collected on the laser scanners.

Another project team investigated possible solutions for autonomous charging of the forklift batteries. The result was in favour of an AI-based robot that connects the charging plug to the forklift’s charging socket. The rear of the truck was modified accordingly and an automatically operated charging flap was added to protect the charging socket from dirt and splash water.

More Options with new Tugger Trains

Posted on by David Priestman

Customized solutions designed primarily for either indoor or outdoor use can now be implemented thanks to new tugger trailer frames from Linde Material Handling (MH). Equipped with application-specific functions, comfortable and safe for operators and gentle on transported goods, the frame modules combine with tow tractors from the Linde product portfolio to form custom-fit Logistic Train solutions that make horizontal transport and synchronized manufacturing processes even more effective and cost-efficient.

Tugger trains have a firm place in modern industrial production. They transport large quantities of material from warehouses and supermarkets over sometimes long distances in order to make it available at various points in assembly. Consisting of a tow tractor and several trailers, tugger trains are especially common in just-in-time or just-in-sequence production in the automotive or mechanical engineering sectors. The load, which is typically positioned on a trolley or rolling rack, is pushed into the trailer frame and raised. Tugger trains reduce the volume of traffic within a plant and the risk of accidents, while ensuring plannable, reliable logistics processes. Bundled transports can be economical for routes that exceed 160 meters in length.

The requirements vary depending on the area of application. Indoors, space is often tight, while tugger trains operating outdoors usually have to contend with uneven surfaces. “For this reason, in addition to our proven All-Rounder version, we have now expanded our range to include Logistic Train solutions that have been developed for either predominantly indoor or outdoor use,” says Mal Rexhepi, Product Manager Logistic Train Solutions.

New trailer modules for various applications

The Linde LT06-M, LT10-M and LT10-W trailers are designed especially for indoor applications. Usually used in combination with tow tractor P60 C, these frame modules can be freely combined. M-frames are available with 600 kg or 1,000 kg load capacity and are loaded at ground level from one side. They are suitable for transports with predefined start and end points. By comparison, the W-frames offering 1,000 kg capacity can be loaded and unloaded from both sides, which makes their use more flexible. If routes are changed later or new stops added, it does not matter on which side these stops are located. The centrally positioned axle with two wheels gives the Logistic Train great manoeuvrability. For example, an aisle width of 3.9 meters is sufficient for a tow tractor with four attached frames for Euro pallet trolleys to make a U-turn. Added to this is the low dead weight of the trailers, the simplest version weighing in at only 158 kilograms. This enables the train to achieve higher travel speeds, which has a positive effect on handling performance.

By contrast, the LT16-Ch and LT16-BMh outdoor models, usually towed by the Linde P250 tractor, are optimized for use in outdoor areas. They are equipped with super-elastic tires measuring 368 mm in diameter and 115 mm wide that absorb shocks and vibrations caused by uneven ground. The robustly constructed frames feature two axles for up to 1,600 kg load capacity, all-wheel steering for high manoeuvrability and directional stability, and a hydraulic lift system for gentle trolley lifting. Two designs are available and can be freely combined: a C-frame (Ch) and a Bridge-frame with adjustable middle support (BMh) that can be loaded on both sides. Numerous equipment options are on offer to lend additional robustness and safety to the Logistic Train for outdoor conditions. These include weather protection, options for enhanced visibility, mud flaps for the wheels and a mechanical overrun brake that ensures safe operations on downhill and uphill gradients.

The two new Logistic Train solutions complement the proven, powerful Linde LT10-C to LT16-BM series. In combination with the Linde P80 tractor, these bring to bear their advantages as “all-rounders” for transports both inside and between halls. Three frame versions are available for the trailers which offer a maximum load capacity of 2,000 kg: C-frames (LT-C), Bridge-frames that can be loaded and unloaded from both sides (LT-B) and Bridge-frames with integrated middle supports (LT-BM).

High safety and performance across all models

Safe transport and loading operations are ensured as standard across all Linde trailer models by the mechanical load lock, which closes automatically after the trolleys have been pushed in. The lifting function of the frames is centrally controlled from the operator’s platform. When the driver gets into the tow tractor, the load is automatically raised; when he or she gets out, it is lowered. An automatic immobilizer prevents the train from starting up when the trailers are lowered and deactivates the lowering function while in motion. An assistance system automatically throttles the speed of the tractor during cornering.

In conjunction with Logistic Trains, the Linde range offers numerous trolleys of different sizes, equipment and tires for payloads of 1,000 kg. They are suitable for transporting pallets and containers and can be equipped with modular rack superstructures for small load carriers. In addition, an optionally available tugger train guidance system aids drivers on complex routes with variable end points and directs them along the optimal route to individual stations.

Pallet Trucks for Loading/Unloading

Posted on by David Priestman

With the T16 P to T20 P models, Linde Material Handling (MH) is launching two new compact pallet trucks with a foldable operator platform. Offering 1.6 and 2.0 tons load capacity, respectively, and a width of just 720mm, the vehicles are designed for use in a wide range of applications and are ideally suited for working in confined spaces. Thanks to speeds of up to 8.5 km/h, gradeability of up to 20 percent, and new comfort and safety features, they enable efficient fast transportation of goods over short and medium distances as well as loading and unloading operations. The pallet trucks are available with a choice of either lead-acid or the latest generation of lithium-ion batteries. Fleet management and connectivity ensure productive operation and effective service.

“Confined spaces present a particular challenge when it comes to loading and unloading trucks as well as in adjacent goods distribution areas,” says Peter Klug, Product Manager Warehouse Technology Germany at Linde MH. “When operating between closely-spaced pallets on the truck loading area or along unclear routes through cargo handling zones, drivers need to have their equipment one hundred percent under control. Accordingly, they appreciate compact, ergonomic vehicles that enable them to work safely and quickly,” explains Klug. With the Linde T16 P and the Linde T20 P, there are now two newly developed vehicles available for the fast movement of goods at the truck ramp and over short to medium transport distances. “The foldable platform allows employees to drive the truck, which saves time and energy. Wherever pallets must be manoeuvred with centimetre precision, the platform and side bars can be folded back up in no time at all,” explains the product manager.

In the Linde portfolio, the Linde T16 P and T20 P models are the link between pedestrian-only vehicles and the recently introduced, high-performance models with foldable or fixed stand-on platform: Their performance is designed to meet the requirements of light to medium-duty applications, while at the same time featuring premium comfort and safety equipment. Additionally, the new trucks are available with various energy options and state-of-the-art on-board electronics and connectivity equipment.

Customized for specific applications

The 1.3 kW three-phase AC motor accelerates the vehicles to a maximum speed of 8.5 km/h; however, speed limits can also be set via various parameters. In difficult situations, the automatic booster effect provides higher torque when additional power is needed, e.g. when driving out of a pothole or pulling out a foil-wrapped pallet that is stuck in the truck. On slopes, the pallet trucks have plenty of reserve under their non-deformable engine hood thanks to gradeability of 15 percent (Linde T16 P) and 13 percent (Linde T20 P) when loaded, and 20 percent when unloaded. Furthermore, the electric steering system allows smooth and precise control even under full load, while the five-point contact configuration with a centred drive wheel and sprung castor wheels keeps the unit stable during transport. Optional integrated onboard chargers free drivers from having to rely on fixed charging stations.

Increased comfort and safety

Additionally, the trucks offer further optimizations with regard to safety and comfort. The sideguards, which keep the operator safely within the chassis contours, are more robustly designed and padded on the new models. The special Linde tiller head now has an activation angle of 65°, which is convenient for drivers with shorter stature. The stand-on platform has been enlarged to 663mm and, with a height of 162mm, allows easy access for the driver. Suspended and made of non-slip rubber, it also dampens vibrations and shocks, thus creating the basis for fatigue-free working. A new option is the metal accessory bar, to which work lights, scanners or the Linde Blue Spot can be attached. Another equipment option is the load guard which prevents the load from sliding toward the operator.

Linde Material Handling GmbH, a KION Group company, is a globally operating manufacturer of forklift trucks and warehouse trucks, and a solutions and service provider for intralogistics. With a sales and service network that spans more than 100 countries, the company is represented in all major regions around the world.

Pallet Productivity Boost at the Ramp

Posted on by David Priestman

With ten technically improved models of pallet trucks, pallet stackers and double stackers, customers of Linde Material Handling (MH) can now make their loading and unloading processes even more productive. In all model variants, the stand-on platform is decoupled from the chassis as standard to protect operators from vibrations and impacts. An innovative swivel castor system provides additional stability during transport and load handling. Offering more advantages such as travel speeds of up to 14 km/h, a further developed, ergonomic power steering, and innovative safety and energy solutions, the trucks make a noticeable contribution to increased handling performance.

“Goods in and dispatch are the warehouse areas associated with the most demanding tasks in the intralogistics flow of goods,” asserts Peter Klug, Product Manager Warehouse Technology, Linde Material Handling. At these interfaces of internal and external logistics, especially at peak times, many people and industrial trucks work simultaneously in a limited space, moving large quantities of goods. To ensure that everything runs smoothly and, above all, safely between truck ramps, docks, containers and storage areas despite considerable time constraints, the equipment must be precisely designed to suit operators’ requirements. What is needed are powerful, ergonomic and safe vehicles that are service-friendly and digitally connected. “The new Linde models with fixed and folding driver’s platforms are geared towards meeting these high customer demands,” states Klug.

A unique product on the market

“The design of the SP model versions with a fixed driver’s platform is a truly unique selling proposition throughout the industry,” Peter Klug explains. A characteristic feature of the 2.0- and 2.5-ton capacity pallet trucks (Linde T20 SP and T25 SP), 1.4- and 1.6-ton capacity pallet stackers with a maximum lifting height of 5.3 meters (Linde L14 SP and L16 SP), and 1.2- and 1.4-ton capacity double stackers (Linde D12 SP and D14 SP, and Linde D12 HP SP) is the steel apron that extends far around the driver’s platform. It keeps the operator within the vehicle contour, provides a stable, padded backrest and effectively protects against injury in the event of jostling and collisions. Another notable feature is the slightly rotated position of the operator who stands at a 45° angle to the direction of the forks. This allows him to keep an eye on his surroundings in any direction of travel without having to change his body position or turn his head. This relaxed posture not only aids in driving manoeuvres during day-to-day operations, but also prevents tension and long-term health problems in the back or neck area.

While the SP models with fixed platform are designed to frequently cover longer distances, the AP models demonstrate their advantages in narrow areas that are difficult to access. For example, to reduce the turning radius in very tight spaces, the stand-on platform of the Linde T20 AP and T25 AP pallet trucks (with load capacities of up to 2.0 and 2.5 tons, respectively) and the Linde D12 HP AP double stackers (with a load capacity of up to 1.2 tons) can be folded up. For a higher level of safety, the creep speed function can be activated which adapts the travel speed to the tiller’s angle of inclination.

Power for loading and transporting goods

Both the models with fixed and folding driver’s platform are optimized to deliver maximum performance. A 3 kW three-phase motor enables the vehicles to accelerate up to 14 km/h without load. To effectively absorb vibrations and shocks caused by uneven ground, the driver’s platform and the tiller are decoupled from the chassis as standard on both AP and SP trucks. This unique feature is exclusive to Linde. It offers the advantage that drivers stay alert and focused for longer and their health is protected in the long term. Additionally, an innovative castor system has been developed to keep the load as stable as possible on the forks. Large swivel castors with shock absorbers compensate for vibrations and automatically adapt to the driving situation and speed. This ensures a high level of safety and increases productivity.

If particularly high power is needed on the ramps, the High Performance (HP) double stacker models come into play. They offer high travel and lifting speeds, while at the same time featuring a stable 5-point configuration with a centred drive wheel, and either mechanically sprung or hydraulic castor wheels.

New options for individual customer requirements

The SP version models are equipped with another safety feature: the Linde Feet Detection assistance system. As soon as the driver’s feet leave the sensor-protected area, the truck slows down in a controlled manner. To alert pedestrians and other drivers of an approaching vehicle, the SP versions offer the newly integrated ‘Linde BlueSpot’ warning light emitter. Both the SP and AP models will feature a new module of the ‘Linde connect’ fleet management solution from next year: ‘Zone Intelligence’ allows individual zones to be defined. If a vehicle enters a defined storage area, the travel speed is automatically reduced.

Wide and deep storage compartments, which can be used to store wrapping paper, work gloves, writing utensils etc., ensure effective workplace organization. The range of holders has been expanded once again to keep the necessary work materials close at hand. Another new option is the colour multifunction display. Thanks to the higher contrast, information on operating hours, battery status and maintenance status is clearly visible even in difficult lighting conditions.

New, so-called trough batteries have been designed for both lithium-ion and lead-acid batteries so that customers can choose and retrofit as they wish. Integrated on-board chargers are available for both battery options. The digital vehicle architecture enables predictive maintenance, and new functions can be added to the vehicles at any time via software updates. Finally, all data can be transparently managed via the digital twin.

Linde Producing Hydrogen for in-house Material Flow

Posted on by David Priestman

It is a pilot project that is unparalleled in this industry in Germany and even throughout Europe: Using its own infrastructure, Linde Material Handling (MH) is now producing green hydrogen to power 21 fuel cell forklifts of its in-house fleet. On Thursday, May 11, the new hydrogen production facility and vehicles were officially put into operation at the Aschaffenburg site. The investment is being funded by the German Federal Ministry of Digital Affairs and Transport (BMDV), coordinated by NOW GmbH and implemented by Project Management Jülich (PtJ). The goal is to gain experience and build up expertise in order to be able to provide customers with comprehensive advice and support on the use of hydrogen in material flow processes.

“The topic of energy is emerging as one of the major challenges of this decade and beyond,” Stefan Prokosch, Senior Vice President Brand Management Linde Material Handling, said at the inauguration ceremony. “In our search for potential solutions, we identified hydrogen as an option in the energy mix of the future.” He pointed out that this applied especially to applications in intralogistics, because, in addition to potential climate neutrality, the rapid refueling of industrial trucks with hydrogen during intensive multi-shift operations posed a major advantage. “A three-minute refueling time corresponds to a comparable charging power of about 480 kW,” he explained. In addition, the energy carrier could act as an energy store with the increased use of renewable energy sources in the future, for example to temporarily store electricity generated by means of photovoltaics or wind power. “We want to have the entire range of energy supply options in our portfolio so as to be able to offer our customers the best possible solution for their specific needs. With this strategy, we will also be able to remain flexible and open to different developments. After all, no one knows exactly where this journey will actually end up,” explained the top brand manager.

Demonstrating courage, breaking new ground

Around 2.8 million euros have been invested in the planning and construction of the hydrogen infrastructure. The hydrogen production facility was built within a period of eleven months on a 280-square-meter area conveniently positioned within the manufacturing and assembly plant. Around 50 subcontractors were involved in building the hydrogen infrastructure under the direction of general contractor Covalion, a Framatome brand, and Linde Material Handling’s construction department.

“With the commissioning of the facility and forklifts, we ourselves are becoming hydrogen producers and users and will thus be able to further expand our technological expertise. This will eventually also benefit our customers because the experience we gain in planning, building and operating the plant and using the fuel cell forklifts will be passed on to them as part of future material flow projects,” stated Prokosch. At the same time, the decentralized on-site hydrogen infrastructure will serve as a showcase for other interested groups. “We will be demonstrating how the use of renewable energy sources can work in practice,” the brand manager added.

Kurt-Christoph von Knobelsdorff, CEO and spokesman of NOW GmbH: “Lighthouse projects like this one undertaken by Linde Material Handling are of great importance for the further ramp-up of hydrogen and fuel cell technology. They demonstrate what is already possible in the area of intralogistics and they make it clear that the transformation towards climate neutrality has gained momentum in the non-road sector as well. Companies that are leading the way in this regard and sharing their experience in networks such as the Clean Intralogistics Net are already benefiting today, ensuring their success far beyond tomorrow.”

Michael Kraus, project manager at Framatome (Covalion): “The project was a challenge, as well as an opportunity to demonstrate our skills and expertise. Planning the project and building the facility took a total of about three years – and we were able to accompany Linde Material Handling from our very first meeting to the approval process and the first fuelling of the industrial trucks. We worked closely with the project management team to meet the specific individual requirements of the project and find the best possible solution.”

State-of-the-art technology in inconspicuous containers

The components of the hydrogen infrastructure comprise several modules. The centrepiece is a PEM (polymer electrolyte membrane) electrolyzer, which is set to produce 50 kg of hydrogen per day. Here, purified and deionized drinking water is separated into oxygen and hydrogen with the help of green electricity. In another container, the hydrogen is gradually compressed to 450 bar and then fed into high-pressure storage tanks via piping and valves. A software-controlled valve system regulates the supply line to the dispenser, the gas pump. Here, employees can connect their vehicles in just a few simple steps. The refuelling process is completed within just a short time. The high-pressure storage tank is designed to store up to 120 kg of hydrogen at 450 bar so that even peak demand caused by increased refuelling processes at shift changes can be covered.

A total of 21 electric counterbalanced trucks with fuel cell hybrid systems, which comprise twelve Linde E50s with a load capacity of five tons and nine Linde E35s with 3.5 tons load capacity, replaced the previously used IC models. As part of the plant fleet, they are used for loading and unloading trucks and supplying the assembly lines with large and heavy components such as counterweights, pre-assembled frames or driver cabs, among other things. “The vehicles do not produce any emissions during operation,” Prokosch emphasizes. Hydrogen and oxygen in the ambient air react in the industrial trucks’ fuel cell system. The electrical energy generated charges a lithium-ion battery that powers the forklift; water and heat result as the only ‘by-products’.

The generation and use of hydrogen takes place directly where intralogistics operations are carried out. In addition to Linde forklifts, other technical solutions offered by the company are used as well. For example, the explosion-proof access control system of the Linde:connect fleet management solution ensures that only authorized and trained persons can use the hydrogen facility. Furthermore, the explosion-proof “Safety Guard” assistance solution at the dispenser and in the vehicles automatically reduces the driving speed in the vicinity of the filling station. Last, but not least, the ‘Linde Energy Manager’ solution enables the intelligent planning and control of energy demands throughout the site, thus avoiding power load peaks and allowing for cost optimization.

Hydrogen technology made by Linde MH

Linde MH is considered one of the pioneers in the use of hydrogen in intralogistics, having developed the first fully operational prototype forklift with fuel cell drive as early as 2000. Since 2010, fuel cell forklifts have been integrated into the company’s series production, and as of today, 80 percent of the series, including counterbalanced forklifts, tow tractors and pallet stackers, can be ordered with this energy option as a ‘customized solution’ with hydrogen drive. In numerous studies and projects, Linde MH and its partners from industry and science have demonstrated the conditions under which fuel cell forklifts are marketable and economical today. This is the case especially if a hydrogen infrastructure is already available on site or if highly pure hydrogen is produced as a waste product in the operational process. Fuel cell forklifts are also suitable for multi-shift operation entailing intensive use and a high number of annual operating hours indoors, or where there is limited space for charging or battery changing facilities, which are ultimately intended to be eliminated.

Along with the construction of Linde MH’s hydrogen infrastructure in Aschaffenburg, parent company KION GROUP AG is pressing ahead with the development and production of its own fuel cell systems. At the LogiMAT trade fair, Linde MH presented its first own 24-volt system for warehouse equipment, which was developed at the Aschaffenburg site. An approved funding decision has already been received for the development of a 48-volt fuel cell system, and the team is working on rapid implementation. “By bringing the development of fuel cell systems and lithium-ion batteries in-house, we will also have the opportunity in the future to design our own fully integrated fuel cell hybrid systems that are precisely tailored to the requirements of material handling equipment,” outlined Prokosch.

Charge Management Controls Energy Costs

Posted on by David Priestman

The new “connect:charger” module as part of Linde Material Handling’s (MH) fleet management solution makes the charging processes of battery-powered industrial trucks transparent and reduces electricity costs while maintaining consistent, high vehicle availability through prioritization, defined charging time slots and power limits. Suitable for use across industries, the quick-to-install software and hardware solution proves its worth even with small fleets and will be launched in time for the LogiMAT trade show.

“Peak demands in energy are among the main causes of skyrocketing costs when it comes to operating electric industrial trucks,” says Stefan Roth, Product Manager Energy Systems at Linde Material Handling. Operators of forklift trucks and warehouse equipment powered by lithium-ion batteries are especially likely to experience this because part of the concept with these applications is to charge the batteries regularly during the day in order to continuously extend their runtime. However, if too many employees connect their electric vehicles to the chargers at the same time, for example during breaks or after the end of the work shift, the power demand increases rapidly. In the case of lithium-ion batteries, this is compounded by the fact that fast charging is associated with significantly higher power demand than with the lead-acid variant.

“As the number of consumers increases, so does the risk that peaks in power consumption will occur,” Roth points out. “These short-term peaks can lead to permanent cost increases if the electricity tariff is linked to compliance with certain limit values,” he adds. But even if there are no limit values involved, with larger fleets it can be difficult to decide when to charge which vehicles in order to ensure their availability or to move charging to daytimes when electricity rates are cheaper. “All these requirements can be handled quickly and easily when using our digital charge management system, connect:charger,” explains Stefan Roth.

Intelligent charging

To do this, the new Linde system links up to 50 chargers in a network with a central hardware unit, which automatically controls the power demand according to predefined rules. Additionally, a dashboard allows forklift drivers and fleet operators to retrieve all the relevant information. For example, they can see when a particular industrial truck is ready for use again or how much energy the individual chargers have consumed over the course of the day. The dashboard also allows settings to be made with just a few clicks to adapt the charging behaviour to operational requirements. “Fixed charging times or maximum power levels can be defined. It is also possible for fleet operators to give individual chargers priority over others, for example, if a vehicle’s battery charge is below 50 percent,” explains product expert Roth. The intelligent charge management algorithm coordinates the various specifications and allocates appropriate capacities to the chargers.

There are two options as regards data transmission from the chargers to the control unit: Initially available at the market launch will be the wired solution (for up to 50 chargers). However, a wireless version will also be on offer shortly. Furthermore, there are plans to integrate additional software functions ranging from dynamic charge management and a cloud-based application to the integration of the charge management solution into a holistic energy management solution. The Linde connect:charger module can also be retrofitted, provided the charging devices feature an integrated interface (from year of manufacture 2018).
