| description | A hydraulic control system for a self-loading scraper elevator drive having a plurality of pumps for combined control of the scraper bowl, ejector, and elevator drives, the flow from the pumps being selectively combinable under the control of an operator to vary the speed of the elevator drive to accommodate different conditions of machine operation. The system permits more efficient utilization of the available engine torque which must be used for propelling the vehicle and driving the scraper bowl, ejector and elevator. |
