High rack warehouses, logistics centres and refrigerated warehouses require forklift trucks that can reach the greatest of heights in the narrowest of spaces. The Linde R10 – R25 reach trucks were developed specifically for these requirements. As nimble special-purpose trucks, they boast exceptional handling performance when storing and retrieving pallets in rack levels up to 13.4 metres high. Under these challenging conditions, the pressure is particularly on the operator to move an ever-increasing volume of goods safely, precisely and quickly. The key to maximum productivity is the perfect interplay between man and machine. To achieve this, Linde developed a new interface: the Multifunction Lever.
A tool for all occasions
It makes operating the R10 – R25 reach trucks effortless. Its extraordinary shape, which fits perfectly in the hand, creates a seamless union between operator and truck for safe, easy and efficient operation.
Modelled on the human hand
Our hands are indispensable for many everyday activities, so they deserve special protection. The top priority when developing the Multifunction Lever was to make operating it less strenuous on the operator’s hand. In collaboration with the Fraunhofer IAO, Linde designed an ergonomic model on which all finger joints and areas of the palm can move. This study formed the basis for the unique shape of the human machine interface. Developed in partnership with Porsche Design, it offers excellent ergonomics and easy, fast operation.
The shape of the Linde Multifunction Lever is perfectly adapted to the human anatomy. The operator’s hand sits in its natural, relaxed position on the control lever, which creates an almost organic connection between operator and truck. Linde was particularly interested in ensuring an accurate fit for hands of all sizes. This means that it can be comfortably used by shorter as well as taller operators without causing fatigue.
- Joystick as an anatomically precise counterpart to the hand
- Relaxed operation with comfortable posture
- Optimised for all hand sizes
The Linde Multifunction Lever makes it possible to carry out all the essential control functions on the 1120 series reach trucks with one hand. The forward, back, raise and lower functions can be controlled with the hand in all four directions. This intuitive arrangement allows the operator to focus entirely on the load and achieve higher handling speeds. A unique feature is the integrated side shifter-centring and horizontal alignment of the forks. Both can be controlled on two wheels with slight movements of the index and middle fingers. This makes load handling easier as the fork can be centred before storage or retrieval. This means that the operator can use the maximum adjustment path in all directions to make corrections. The Multifunction Lever is available in two different designs: with and without direction of travel control. It is also designed for use in refrigerated warehouses, down to temperatures of -30 °C.
- All essential control functions in a single unit
- Integrated side shifter control and horizontal alignment of the forks
- Designed for use in refrigerated warehouses
When performing repetitive transport and stacking tasks, there is a high risk of fatigue. Linde is combating this fatigue with the new Multifunction Lever, whose ergonomic design allows the hand to be relaxed and alleviates the strain on the operator. The fingertip control allows pallets to be transported and stacked with the slightest of movements without exerting any force. The lower arm remains comfortably positioned on an armrest, which keeps the arm relaxed during the demanding storage and retrieval processes. The control helps carry out precise, safe manoeuvres and prevent accidents.
- Ergonomic shape for fatigue-free working
- Control without physical exertion
- Work safety by alleviating the strain on the operator
The armrest means that all control movements occur from the wrist, so no unnecessary strain is placed on the lower arm. This makes the millimetre-perfect manoeuvring of pallets a breeze, even at great heights – all without even looking at the control lever. The operating concept is so intuitively designed that no second glance is needed to check whether the hand is in the right position.
- Armrest for calm, precise movements
- Focus on the load for millimetre-perfect operation
The benefits of the Linde Multifunction Lever at a glance
Rack Protection Sensor
Distances of several metres separate the pallet from the operator during storage and retrieval activities at high rack levels. While the operator is focused on the goods, there is a risk of collision with the rack. Potential damage is prevented by the Linde Rack Protection Sensor (RPS), which automatically brakes the reach truck. The assistance system measures the distance to the rack within a radius of 5 metres and brings the truck to a standstill from a speed of up to 5 km/h. The RPS supports the operator when carrying out difficult load manoeuvres in tight spaces at great heights, and contributes to safe and efficient operation. At the same time, it saves on costs for protection systems on the racks themselves and on the replacement of damaged storage systems. The Linde Rack Protection Sensor can even be retrofitted in older models.
Green light on the forks
An assistance system that illuminates the forks in green can be added to allow the operator to position the forks at exactly the right height. The green lights ensure optimal visibility of the forks, especially in dark aisles. This optical assistance improves both safety and handling performance.
Linde Vision System
To optimise the often poor view of pallets in high rack rows, the R10 – R25 reach trucks from the 1120 series can be equipped with the Linde Vision System. The video system transmits two camera images on the mast and on the roof so that the operator can clearly follow the pallet, even when faced with high racks. The unique positioning of the mast camera below the forks provides an exceptionally precise view of the forks and pallet.
