Abstract
An industrial truck has a height-adjustable standing and/or sitting arrangement for an operator and steering hydraulics. The standing and/or sitting arrangement is connected with a hydraulic positioning cylinder, which is connected to the steering hydraulics for the height adjustment of the standing and/or sitting arrangement. The positioning cylinder is connected in parallel with a steering motor and can be acted upon from both sides by the steering hydraulics. An electromagnetically actuatable valve, which can be controlled by a control unit, is disposed in a hydraulic line leading to a positioning space of the positioning cylinder associated with the upward movement of the height adjustment. The control unit prevents height adjustment if another work function is being executed by the industrial truck.
