one. The power unit is of S3 duty, which might only be worked intermittently,i.e. 1minute on and 9 minutes off.
2. Clean each of the hydraulic parts concerned just before set up of the energy unit.
three. Viscosity on the hydraulic oil shoud be 15~46 cst, which should also be clean and absolutely free of impurities, N46 hydraulic oil is proposed .
4. Check the oil degree in the tank right after the original operation of your electrical power unit.
5. Oil modifying is required after the initial a hundred operation hrs, afterwards as soon as each 3000 hours.
Power UNITS FOR DOCK LEVELER four
This electrical power unit is deigned for those dock levellers which will need floating ramps with an emergency end perform. 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 running. An emergency prevent will likely be recognized although the solenoid valve is energized. The lowering speed of the two the ramp and also the lip is adjusted by the needle valves during the method.
Electrical power UNITS FOR DOCK LEVELER 3
This Dock leveler electrical power unit merely 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 even though the descent. Both the ramp and lip f of each functions are controlled by a needle valve. The needle valves are adjustable to realize the wanted descent velocity of each perform. The 2nd relief valve assures the key platform to get floating under load when the dock leveler is getting used for loading and unloading the items, consequently guarding the dock leveler effectively.
