Exclusive Notes
1. The power unit is of S3 duty, which might only be worked intermittently,i.e. 1minute on and 9 minutes off.
2. Clean all the hydraulic elements concerned ahead of installation of the power unit.
3. Viscosity of the hydraulic oil shoud be 15~46 cst, which need to also be clean and absolutely free of impurities, N46 hydraulic oil is proposed .
four. Check the oil degree inside the tank just after the preliminary operation on the power unit.
5. Oil changing is required right after the original one hundred operation hrs, afterwards the moment every single 3000 hours.

General Description
This power unit is deigned for those dock levellers which want floating ramps with an emergency cease perform. The ramp will rise when 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 halt are going to be recognized when the solenoid valve is energized. The decreasing pace of each the ramp along with the lip is adjusted by the needle valves inside the program.

Basic Description
This Dock leveler energy unit simply raised the ramp when the motor is activated, when the ramp has reached full extension the sequence shifts to extend the lip. The ramp and lip are lowered by separate solenoid valves although the descent. Both the ramp and lip f of every functions are controlled by a needle valve. The needle valves are adjustable to realize the wanted descent speed of each perform. The 2nd relief valve ensures the key platform to be floating beneath load once the dock leveler is being used for loading and unloading the products, therefore protecting the dock leveler efficiently.
