This power unit is deigned for those dock levellers which need floating ramps with an emer-gency stop function. The ramp will rise when the pump is running.The lip will expend auto・matically when the ramp cylinder finishes its stroke. The ramp cylinder will retract when the pump stops running. An emergency stop will be realized while the solenoid valve is energized. The lowering speed of both the ramp and the lip is adjusted by the throttle valves in the system.
