1. The electrical power unit is of S3 duty, which could only be worked intermittently,i.e. 1minute on and 9 minutes off.
two. Clean each of the hydraulic parts 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 advisable .
4. Check the oil level in the tank right after the original operation of the energy unit.
5. Oil transforming is required immediately after the first 100 operation hours, afterwards after every 3000 hrs.
Energy UNITS FOR DOCK LEVELER four
This energy unit is deigned for those dock levellers which require floating ramps with an emergency stop function. The ramp will rise when the pump is working.The lip will expend immediately once the ramp cylinder finishes its stroke. The ramp cylinder will retract once the pump stops working. An emergency stop will probably be realized when the solenoid valve is energized. The decreasing velocity of each the ramp and the lip is adjusted from the needle valves during the technique.
Energy UNITS FOR DOCK LEVELER three
This Dock leveler electrical power unit simply just raised the ramp once the motor is activated, when the ramp has reached complete extension the sequence shifts to extend the lip. The ramp and lip are lowered by separate solenoid valves although the descent. Each the ramp and lip f of every functions are managed by a needle valve. The needle valves are adjustable to accomplish the wanted descent speed of each function. The 2nd relief valve ensures the key platform for being floating under load once the dock leveler is getting used for loading and unloading the goods, therefore defending the dock leveler correctly.
