ABSTRACT:
Each of the swivel-mounted wheel axles of a chassis can be manually positioned by means of an adjusting device, which includes a lever, into a first position for driving the chassis straight ahead or in reverse with respect to its longitudinal dimension, or else into a second position for turning the chassis about a fixed spot. In each position, the swivel-mounted axle is fixed in this position by means of a locking pin, which can be brought into the locked position by raising the lever or into the disengaged position by lowering the lever. A locking detector is assigned to each position. The locking detectors which have been assigned to the setting for driving straight or to that for turning on the spot are each incorporated into a separate control circuit, these control circuits permitting the starting of the wheel drives only when the swivel-mounted wheel axles have been properly set and locked for either driving straight or turning about the fixed spot.
