Special Notes
1. The electrical power unit is of S3 duty, which may only be worked intermittently,i.e. 1minute on and 9 minutes off.
2. Clean all the hydraulic elements concerned ahead of set up of the energy unit.
3. Viscosity in the hydraulic oil shoud be 15~46 cst, which really should also be clean and absolutely free of impurities, N46 hydraulic oil is suggested .
4. Check the oil degree within the tank right after the first operation in the electrical power unit.
5. Oil changing is required following the first a hundred operation hrs, afterwards when every single 3000 hrs.
Energy UNITS FOR DOCK LEVELER 4
General Description
This power unit is deigned for all those dock levellers which need floating ramps with an emergency halt perform. The ramp will rise when the pump is running.The lip will expend immediately when the ramp cylinder finishes its stroke. The ramp cylinder will retract when the pump stops operating. An emergency end will probably be realized while the solenoid valve is energized. The lowering pace of the two the ramp as well as lip is adjusted from the needle valves during the program.
Energy UNITS FOR DOCK LEVELER 3
Standard Description
This Dock leveler electrical power unit simply raised the ramp once 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 whilst the descent. Each 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 each perform. The 2nd relief valve ensures the key platform to get floating below load when the dock leveler is being used for loading and unloading the items, consequently safeguarding the dock leveler proficiently.
