HSDLB series power pack dock leveler is designed as hydraulic power pack unit for dock leveler equipment. The power pack dock leveler is started by electric motor, the directional valve in the hydraulic circuit switches(0.5s~1s) the pilot oil when the hydraulic pump generates the hydraulic pressure, which is pressurized the hydraulic cylinder to lift the heavy load. The lift table will not fall down if the electric motor stops since the check valve is isolated the returned oil, keeping the heavy load in the level for certain period and will slowly fall down if adjusting the pressure relief valve and the speed of drop down is available to be adjusted by oil return throttle valve.
Unloading pressure valve in power pack dock leveler will be able to use when the motor off, by manually to release the pressure and to achieve a downward movement; unscrew manual discharging oil valve nut, manually screw counterclockwise rotation of 30 degrees can be decreased the pressure and load. After the fall, tighten the screws, and manually install nut tightly.
