Special Notes
one. The electrical power unit is of S3 duty, which could only be worked intermittently,i.e. 1minute on and 9 minutes off.
two. Clean all the hydraulic elements concerned prior to installation of the energy unit.
3. Viscosity of the hydraulic oil shoud be 15~46 cst, which should also be clean and absolutely free of impurities, N46 hydraulic oil is proposed .
four. Check the oil level inside the tank right after the initial operation with the power unit.
five. Oil modifying is required following the first 100 operation hours, afterwards when every single 3000 hours.

Electrical power UNITS FOR DOCK LEVELER 4
General Description
This electrical power unit is deigned for anyone dock levellers which need floating ramps with an emergency halt function. The ramp will rise once the pump is running.The lip will expend immediately once the ramp cylinder finishes its stroke. The ramp cylinder will retract when the pump stops working. An emergency end are going to be recognized while the solenoid valve is energized. The decreasing velocity of both the ramp as well as lip is adjusted by the needle valves while in the process.

Energy UNITS FOR DOCK LEVELER 3
Common Description
This Dock leveler power unit merely raised the ramp once the motor is activated, once the ramp has reached complete extension the sequence shifts to extend the lip. The ramp and lip are lowered by separate solenoid valves while the descent. Both the ramp and lip f of each functions are controlled by a needle valve. The needle valves are adjustable to accomplish the wanted descent velocity of each perform. The 2nd relief valve guarantees the principle platform to be floating under load once the dock leveler is being used for loading and unloading the products, as a result protecting the dock leveler effectively.
