ABSTRACT:
In a lift truck having one steerable powered drive wheel assembly and a steerable idler wheel assembly interconnected by a pair of links and a crank, steering is accomplished by means which apply torque directly to the drive wheel assembly. The steering rotation of the drive wheel assembly rotates the idler wheel assembly, so that forces transmitted through the links and the crank to steer the idler wheel assembly are independent of drive wheel loading, and less motive force is required to steer the truck at large cramp angles.
