To provide an industrial truck having a highly reliable steering device allowing safe operation in different steering operation modes.
This method is for steering the industrial truck. This device comprises a control unit having at least a steering control device 28 and a movement control device 30. The steering control device 28 has different steering operation modes for three or four steerable wheels, and these wheels are controlled with basic positions taken as start positions. Each of the steering operation modes controls the driving and/or the braking of the industrial truck by using a set of the movement parameters controlled with a basic position used as a start point and having at least one steering operation mode and a set in which the movement control device 40 is related to an actual steering operation mode.
