ABSTRACT:
A fork unit mountable on the fixed front plate member of a lift truck comprises a movable frame to which the forks of the fork unit are restrained by respective shanks lying in the same plane that contains the frame. Between the upper and lower edges of the plate and the frame, provision is made for reciprocal coupling and a guide, and a hydraulic cylinder for translating the frame with respect to the plate acts between the plates and frame. The concept of side-shift device with fork-bearing is thus eliminated and this brings the advantage of a minimal overhang of the load moved by the lift truck.
