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 each of the hydraulic components concerned prior to set up of the power unit.
3. Viscosity on the hydraulic oil shoud be 15~46 cst, which really should also be clean and totally free of impurities, N46 hydraulic oil is advised .
4. Check the oil degree inside the tank just after the original operation in the power unit.
5. Oil changing is required immediately after the initial one hundred operation hours, afterwards after each and every 3000 hours.
Electrical power UNITS FOR DOCK LEVELER four
This electrical power unit is deigned for those dock levellers which need to have floating ramps with an emergency prevent perform. The ramp will rise when 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 running. An emergency halt are going to be realized although the solenoid valve is energized. The lowering velocity of the two the ramp plus the lip is adjusted through the needle valves from the technique.
