Abstract: A method for the control of an industrial truck during order picking by an industrial truck with at least one environment sensor for the detection of the relative position of an operator in the environment of the industrial truck. The method includes moving the industrial truck using a control system. As the position of the operator changes, and when the operator stops, the industrial truck is stopped at a freely selectable distance specified in advance in the longitudinal direction of the vehicle between a reference point of a load handling device of the industrial truck and the position of the operator.

Abstract: An industrial truck has a lifting mast and vertically movable load handling device located on the lifting mast. The lifting mast has a lifting height measurement system having a light emitter that emits a light beam, a receiving element, an optical alignment element, a target element, and a measurement path located between them, the length of which measurements path varies with the lifting height. The alignment element and/or the light emitter has a beam-forming optical system, in particular a beam-expanding optical system, so that at the maximum lifting height the reflecting target is inside the expanded light beam of the light emitter in all positions of the allowable maximum bending of the lifting mast.
