ABSTRACT:
A combined steering and control head connected by a shaft to guide a floor conveyor vehicle having a fork lifting driving mechanism. This steering head has handles at the end of the shaft which are arranged on both sides of a shaft horn and are held rotatably with the same axis as driving control devices disposed next to the horn. A lifting and lowering switch for controlling lifting movement of a loading fork is arranged adjacent to an end face of the horn. The driving control device consists of a disk-shaped segment at the circumference of which is a first actuating surface extending transversely with respect to the handle. A second actuating surface is arranged at the circumference of the segment opposite the first surface such that at least one of the actuating surfaces can be gripped together with an operating surface of the lifting and lowering switch.
