Power UNITS FOR DOCK LEVELER 4
Standard Description
This power unit is deigned for those dock levellers which have to have floating ramps with an emergency end perform. The ramp will rise once the pump is working.The 
lip will expend instantly when the ramp cylinder finishes its stroke. The ramp cylinder will retract when the pump stops operating. An emergency stop will probably be realized even though the solenoid valve is energized. The decreasing velocity of each the ramp and the lip is adjusted from the needle valves within the procedure.
