Electric forklift truck with automatic guidance - uses hydraulic motors to operate driving wheels and auxiliaries and having function independent of automatic guidance circuit

摘要

The track includes a hydraulic motor/pump unit with a pair of hydraulic motors each coupled to a respective wheel. These driving wheels are mounted in opposition along the central transverse axis of the track. The motor/pump unit also provide for the hydraulic lifting and lowering of the forks and operates other auxiliaries under the control of a distribution block in turn controlled by the programming unit for the truck operation. Pref. the two hydraulic motors are completely independent of the automatic guidance circuit, the differential effect of the driving wheels during cornering obtained by the hydraulic equilibrium effect due to the resistive couples.
