Ramps Take on a Heavy Load For Witron

Logistics specialist Witron has benefited from the strength and versatility of bespoke loading ramps from Thorworld during its construction of a new distribution centre for a retail customer. The largest of the four ramps delivered to the Northwest site had to withstand the weight of a 48-tonne crane.

Thorworld’s involvement came after Witron was let down by its existing ramp supplier. Given the complexity of the distribution centre’s build, and with the clock ticking, Witron needed a reliable alternative, quickly.

“Thorworld stood out as a credible solution provider, they have an excellent reputation in the market and could manufacture ramps to the exact size and weight parameters we required,” commented Duncan Pointon, Business Development Manager UK at Witron.

“Plus, their knowledge was second to none when it came down to our application, giving valuable input as the ramps needed to be moved in and out of pits.”

The four ramps were built and delivered in a phased operation, to suit Witron’s own construction schedule. The first three ramps are being used by Witron to help move plant in and out of the dispatch buffer pits where they assemble automated racking. Thorworld installed the first ramp to demonstrate best practice, while the next two were installed by Witron.

Thorworld returned to install the last – and most complex – of the four ramps. “This was in the CPS pit, which forms part of the 35m High Bay Warehouse. We erect racking at ground level, in strategically located pits. The racking must be installed by crane, therefore we needed a ramp specifically built to allow the crane easy access in and out of the pit,” explained Duncan Pointon.

Ian Langan, Technical and Engineering Director at Thorworld, particularly enjoyed the challenge of designing a ramp capable of withstanding the weight of the crane. “Normally our mobile ramps have a usable width of 2250mm and up to 15,000kg capacity. The crane weighed 48,000KG and required a usable width of 3.5m and a ramp length of 8m,” he said.

“We had to undertake design calculations and finite element analysis (FEA), to ensure the capacities and axle loads could be adequately supported. And then manufacture all four ramps from scratch within a very short timescale!”

Unusually for Thorworld, the four ramps are only needed during the fit-out of the distribution centre and will not be in regular use. Nonetheless, Witron has recognised their long-term value. “All of our DCs are built to a similar specification, so we’ll definitely need the Thorworld ramps again! Until then, we’ll keep them in storage, ready for the next site build,” concluded Duncan Pointon

Pallet Productivity Boost at the Ramp

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.

Ramp up your forklift operations

The arguments for why electric forklifts are better than diesel are well rehearsed. But, for many, a nagging doubt remains: what about ramps and steep slopes where there’s the very real possibility of power drop-off? The problem has been conclusively solved by Mitsubishi Forklift Trucks with its new, patent-pending, AutoBoost feature.

According to Stewart Gosling of RDD, sole UK importers for Mitsubishi forklifts: “AutoBoost senses when power is required by sensing when speed needs maintaining and automatically activating acceleration and torque boosts – precisely when and where they’re needed.”

It is just one in a series of new features that ensure the EDiA EX outclasses any diesel as well as every other 2.5 to 3.5 tonne electric truck.

“Slippery conditions present no problems thanks to a combination of all-wheel steering and another innovation: an electric differential lock. The result is outstanding traction and control, even in the most hostile environments, indoors or outside. At the rear of the truck the steer wheels turn through a massive 100-degree lock to deliver the smallest turning circle on the market for safe operation in the very tightest spaces. Importantly. There is no push back, even when setting off on full lock.”

At the front, both drive motors turn in different directions for better grip and precise handling. Indeed, everything about the new EDiA EX has been designed to inspire confidence: for the operations manager as well as the driver. State-of-the art software automatically adapts performance characteristics to the driving style and ability of each individual operator, making handling totally intuitive.

Alongside that, EDiA’s Intelligent Cornering System calculates the speed, angle and load at the very start of a turn (rather than half-way through it) to automatically adjust truck speed to optimise handling when cornering — maximising throughput and safety. What’s more, by using lithium-ion or Quasar enhanced lead acid batteries with high-speed opportunity charging, EDiA EX users benefit from the same non-stop performance as diesel, including multi-shift working with no battery changes, no topping-up and no maintenance requirements.

“We’re experiencing a huge growth in demand in markets such as transport, logistics, drinks, timber, etc. that have always been staunchly diesel,” reveals Mr Gosling. “It’s no surprise because the EDiA EX offers so much more than and IC engine trucks in terms of safety, productivity and care for the environment. By offering the same power and go-anywhere performance of a diesel counterbalance truck the EDiA EX allows any customer in any industry to reduce their carbon footprint whilst also improving the working environment by eliminating noise emissions as well as pollution.”
