Unique Notes
1. The electrical power unit is of S3 duty, which may only be worked intermittently,i.e. 1minute on and 9 minutes off.
2. Clean each of the hydraulic components concerned in advance of installation of the power unit.
3. Viscosity from the hydraulic oil shoud be 15~46 cst, which need to also be clean and absolutely free of impurities, N46 hydraulic oil is proposed .
4. Check the oil degree from the tank after the initial operation of the electrical power unit.
5. Oil shifting is needed following the original 100 operation hours, afterwards the moment every 3000 hours.

General Description
This electrical power unit is deigned for anyone dock levellers which want floating ramps with an emergency end perform. The ramp will rise when the pump is working.The lip will expend immediately once the ramp cylinder finishes its stroke. The ramp cylinder will retract when the pump stops operating. An emergency quit will probably be realized although the solenoid valve is energized. The reducing velocity of each the ramp plus the lip is adjusted through the needle valves from the procedure.

Common Description
This Dock leveler electrical power unit merely raised the ramp once the motor is activated, once the ramp has reached full extension the sequence shifts to extend the lip. The ramp and lip are lowered by separate solenoid valves while the descent. Each the ramp and lip f of every functions are managed by a needle valve. The needle valves are adjustable to accomplish the sought after descent pace of each perform. The 2nd relief valve ensures the primary platform to become floating beneath load once the dock leveler is getting used for loading and unloading the products, thus guarding the dock leveler successfully.
