K Series 5231 Very Narrow Aisle Truck

The combination forklift or narrow aisles


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.


  • 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.
