Product Description

Hydraulic Power Unit for Dock Leveler

This type of power unit is specially designed for fixed and mobile dock levelers. Under the control of a series of hydraulic valves, the main and auxiliary cylinders support the sequential action of the main board and the backrest of the loading bridge, forming a stable inclined bridge between the platform and the loading vehicle to meet the needs of loading and unloading goods for the entire vehicle.

FAQ - Troubleshooting

What should I do if the motor does not rotate?
Check the accuracy of the connection lines and ensure the power supply is properly connected. Also, verify if the start switch or AC contactor is burned out.
Why is the oil cylinder not rising or rising unsteadily?
This could be due to low oil levels, incorrect oil viscosity, a clogged suction filter, or air leaks in the suction pipe. Ensure the solenoid valve is closed and the motor is not rotating in reverse.
What causes the relief cylinder to fail to descend during unloading?
Common causes include solenoid valve power failure, incorrect input voltage, clogged valve filter screens, or a blocked throttle/pressure compensation valve.
How to solve pressure maintenance failure or cylinder dropping?
Check if the check valve, solenoid valve, or manual valve oil seals are properly sealed. If the valves are clean and sealed, the issue may lie with the actuator (cylinder) itself.
What should I do if the system noise is too loud?
Remove air from the system by working the unit back and forth. Check if the coupling is worn or improperly installed, and ensure the unit is not operating under extreme pressure for extended periods.
What causes oil leakage between the tank and valve block?
Usually, this is caused by a worn or broken O-ring. Inspect the O-ring and replace it if necessary. If leakage occurs at high-pressure parts, professional inspection may be required.
