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.
