Method for operating an industrial truck

摘要

The method involves moving and guiding a mast (8) vertically with a load receiving mechanism (6). The lifting height of the load receiving mechanism is detected with a vertical lift detecting mechanism. The vertical lift detecting mechanism has a travel drive distance detection unit that is provided for detecting a distance traveled (11). The distance (raktuell) traveled to a place (9) of a first crossing is detected by a moving distance detecting unit. The safety distance is detected, and a warning signal and/or an intervention are provided to a drive system.
