Exclusive Notes
1. The electrical power unit is of S3 duty, which can only be worked intermittently,i.e. 1minute on and 9 minutes off.
two. Clean all the hydraulic components concerned before installation of the energy unit.
three. Viscosity of the hydraulic oil shoud be 15~46 cst, which should also be clean and totally free of impurities, N46 hydraulic oil is encouraged .
four. Check the oil level within the tank just after the original operation in the energy unit.
5. Oil transforming is needed immediately after the original a hundred operation hrs, afterwards after just about every 3000 hours.

General Description
This power unit is deigned for those dock levellers which need floating ramps with an emergency cease function. The ramp will rise once the pump is operating.The lip will expend automatically when the ramp cylinder finishes its stroke. The ramp cylinder will retract when the pump stops running. An emergency stop will probably be recognized whilst the solenoid valve is energized. The lowering velocity of the two the ramp and also the lip is adjusted from the needle valves during the system.

Electrical power UNITS FOR DOCK LEVELER 3
Common Description
This Dock leveler energy unit only raised the ramp once the motor is activated, when the ramp has reached complete extension the sequence shifts to lengthen the lip. The ramp and lip are lowered by separate solenoid valves when the descent. The two the ramp and lip f of every functions are controlled by a needle valve. The needle valves are adjustable to realize the desired descent velocity of every function. The 2nd relief valve ensures the principle platform to get floating beneath load once the dock leveler is being used for loading and unloading the goods, so defending the dock leveler proficiently.
