Special Notes
one. The electrical power unit is of S3 duty, which might only be worked intermittently,i.e. 1minute on and 9 minutes off.
2. Clean the many hydraulic elements concerned in advance of installation of the energy unit.
3. Viscosity on the hydraulic oil shoud be 15~46 cst, which need to also be clean and no cost of impurities, N46 hydraulic oil is suggested .
4. Check the oil degree from the tank soon after the initial operation in the electrical power unit.
5. Oil shifting is needed following the original 100 operation hours, afterwards once every 3000 hrs.

Power UNITS FOR DOCK LEVELER 4
Standard Description
This power unit is deigned for those dock levellers which require floating ramps with an emergency cease function. The ramp will rise when the pump is working.The lip will expend automatically once the ramp cylinder finishes its stroke. The ramp cylinder will retract once the pump stops running. An emergency quit might be realized although the solenoid valve is energized. The reducing pace of both the ramp as well as the lip is adjusted through the needle valves during the program.

Electrical power UNITS FOR DOCK LEVELER 3
Basic Description
This Dock leveler electrical power unit basically raised the ramp when the motor is activated, when the ramp has reached total extension the sequence shifts to lengthen the lip. The ramp and lip are lowered by separate solenoid valves while the descent. The two the ramp and lip f of every functions are controlled by a needle valve. The needle valves are adjustable to achieve the preferred descent pace of every function. The 2nd relief valve ensures the main platform for being floating below load once the dock leveler is being used for loading and unloading the products, so guarding the dock leveler efficiently.
