A combination forklift for narrow aisles

The K series man-up turret truck from Linde Material Handling enables high turnaround capacity for order picking and handling processes in high rack warehouses. The powerful drive trains make this possible, as the truck can move and lift at the same time. Also, even at high lift levels the speed remains high, and a high level of residual lift capacity is available.

Various assistance systems are available that help to navigate accurately through the warehouse or to avoid obstacles. In particular, the Linde System Control improves the process; depending on the version, the system adjusts the lift and travel speed according to the weight being transported. There are various versions of the mast, chassis, battery and cab for the very narrow aisle trucks, which can be combined according to usage requirements. There are around 10 million possible truck configurations.

Characteristics

  • Operator must make contact with three points, otherwise they will be unable to move the combination forklift: the hand sensors on the control panel as well as the dead-man’s switch on the cab floor. This prevents incorrect operation which may lead to accidents.
  • Electrically monitored side cabinets must be closed when the platform height is above 1.2 metres.
  • Optional staff protection system continuously scans the aisle and stops the truck if people are in the vicinity.
  • Optional Aisle Safety Assistant detects RFID-tagged or barcode-marked unevenness, obstacles in the shelving, on the floor or on the ceiling and automatically limits the speed, lift height or fork extension at these locations.
  • Service technicians can program general travel, lift and lowering end stops in the truck system, which can be adjusted.
  • The standard, load and weight variants within the 'Linde System Control' assistance system help the operator by adjusting speed and optimising driving behaviour depending on the lifting height, load recognition and load weight.
  • Control panel has an ergonomic design and its position can be adjusted across three axes – for example to aid comfortable working in both a standing and sitting position.
  • Operator can adjust the height and incline of the folding seat.
  • To make work easier, several storage options are available in the large, draft-protected cab.
  • Chassis and cab are decoupled from each other so that less shock is transmitted to the operator.
  • Tilting side barriers are available as an option, they swing outwards if the operator leans on them. This decreases the operator's distance from the shelving, and makes order picking easier for the operator.
  • Knee cushion for comfortable order picking.
  • The colour display of the control panel shows all the important information such as the time, speed, lifting height and steering angle at a glance.
  • Even at high lift levels, the modern drive train technology of the combination forklift can achieve a high speed.
  • High residual lift capacity as well as modern RFID assistance systems enable navigation in the warehouse and handling on the shelving to be carried out more quickly.
  • When using the Linde connect: fleet management system, it is possible to optimise the whole usage cycle of the trucks.
  • Additional support for handling is provided by functions such as the automatic lift height pre-selection and the automatic forks cycle. In this process, the truck automatically carries out three movements during pallet placement or removal at the press of a button.
  • Main and auxiliary lifts can be raised or lowered simultaneously, allowing the operator to reach high-bays in a single step without having to operate the main and auxiliary lifts successively.
  • The forks can be put into position quickly through simultaneous control and can be controlled very easily at a convenient height.
  • The energy generated by braking and lowering the load is restored to the battery, this improves usage duration and cost-effectiveness equally.

The robust technology of the Linde K combination forklift ensures low service costs and a long service life.

  • CAN bus connectivity enables all truck data to be read out on a laptop computer by the service technician making the service process easier.
  • AC motors for lift and movement, and both of the independent braking systems are maintenance-free.
  • With the battery carriage frame, which is available as an option, lateral battery changing is completed rapidly.

Technical Data

Optional Equipment

Modular Truck Design

The combination of the fork camera and crossline laser makes load handling much easier. The crossline laser helps to target the pallet and to pick it up precisely, and the fork camera provides optimum visibility for storage and retrieval at high rack levels.

Attachment Bars

The operator cab can be enhanced with several individual fittings, such as monitor, terminal scanner, storage facilities and writing support.

Operating Panels

For the cab, the customer can choose between a front or divided operating panel. Both variants can be adjusted quickly for working in a standing or sitting position. The integrated full-colour display provides the operator with all the relevant information at a glance, from the speed of the forklift and the lifting height to the steering angle and the time of day.

Tilting Barriers

If the operator leans on the barrier, it tilts outwards by 10cm. This enables the operator to reach the racking better, making order picking easier.

Mirror Module

The equipment package includes a large rear-view mirror as well as lateral working lights to illuminate the working surroundings in the racking. There is also an optional ventilation system available to cool the operator when working at high lift levels in hot weather.

Active Stability Control (ASC)

The ASC is an intelligent assistance system that detects unevenness between the left and right sides of the aisle, and automatically compensates for shocks and vibrations so the truck can achieve its maximum handling performance even on less than perfect floors.

Linde System Control (LSC)

The system provides improved throughput rates and increased safety. The LSC Standard basic version informs the operator of the residual load capacity depending upon the lift height. Other LSC versions automatically adapt the operating, lifting and auxiliary movements to the actual weight of the load being transported and the lift height.

Dynamic Reach Control (DRC)

This system combines all LSC functions and adds intelligent load stabilisation. When storing or retrieving loads, the system adjusts reach according to the current load weight and eliminates lateral mast oscillations. This enables loads to be moved faster and reduces the risk of damage to loads and racks.

Aisle Safety Assistant

The assistance system uses barcodes or RFID tags in the aisle to detect uneven floor surfaces, as well as obstacles on the racks or on the ceiling, and restricts truck functions such as operating and lifting speed, lift height or forks extension at these specific locations.

Warehouse Navigation

The forklift receives operating jobs from the warehouse management system. The system detects the location in the warehouse, as well as the current lift height and guides the forklift truck to the pallet location autonomously, using the fastest and most efficient route. The operator only has to operate the driving function.

Fleet Management

How and by whom are the individual forklift trucks used? What does the forklift truck usage data look like, and is each one roadworthy? Using a combination of software and hardware, the connect fleet management system provides all the answers.

Cold Storage Protection

The K-truck is available for cold store application. Amongst other things, the forklifts are operated with special hydraulic fluid and lubricants and receive a corrosion-proof coating. Additionally, there is the option to choose from a variety of enclosed, insulated cabs. A closed and heated cold store cabin provides comfortable working conditions.
