Distinctive Notes
1. The electrical power unit is of S3 duty, which could only be worked intermittently,i.e. 1minute on and 9 minutes off.
2. Clean all the hydraulic parts concerned before set up of the energy unit.
3. Viscosity from the hydraulic oil shoud be 15~46 cst, which need to also be clean and free of impurities, N46 hydraulic oil is advised .
4. Check the oil degree during the tank right after the original operation of the electrical power unit.
5. Oil transforming is required after the preliminary one hundred operation hours, afterwards when just about every 3000 hours.

Standard Description
This power unit is deigned for anyone dock levellers which need to have floating ramps with an emergency halt function. The ramp will rise once the pump is working.The lip will expend automatically once the ramp cylinder finishes its stroke. The ramp cylinder will retract when the pump stops operating. An emergency cease will likely be realized whilst the solenoid valve is energized. The lowering speed of the two the ramp and also the lip is adjusted by the needle valves within the program.

Basic Description
This Dock leveler energy unit simply raised the ramp once the motor is activated, once the ramp has reached total extension the sequence shifts to extend the lip. The ramp and lip are lowered by separate solenoid valves even though the descent. The two the ramp and lip f of every functions are controlled by a needle valve. The needle valves are adjustable to accomplish the desired descent speed of every function. The 2nd relief valve assures the primary platform for being floating under load once the dock leveler is getting used for loading and unloading the items, so safeguarding the dock leveler efficiently.
