ABSTRACT:
A dual hydraulic motor drive system is provided for powering a material loading elevator of a self-loading scraper vehicle. Such drive system includes a pair of hydraulic motors which are disposed in a fluid circuit having a blocker valve movable between a first position to direct fluid pressure to just one of the motors to provide high speed, low torque operation of the elevator and a second position to direct fluid to both of the motors to provide low speed, high torque operation of such elevator. Actuator means responsive to loading resistance affecting the elevator being effective to automatically position the blocker valve in its first position during normal loading conditions and to shift it to its second position when severe loading conditions are encountered so as to prevent stalling of the elevator.
