Particular Notes
one. The electrical power unit is of S3 duty, which can only be worked intermittently,i.e. 1minute on and 9 minutes off.
two. Clean all the hydraulic parts concerned before set up of the electrical power unit.
3. Viscosity from the hydraulic oil shoud be 15~46 cst, which should also be clean and absolutely free of impurities, N46 hydraulic oil is advisable .
four. Check the oil degree from the tank right after the preliminary operation in the power unit.
five. Oil altering is needed soon after the first one hundred operation hours, afterwards when every 3000 hrs.
Electrical power UNITS FOR DOCK LEVELER four
Common Description
This electrical power unit is deigned for anyone dock levellers which need floating ramps with an emergency cease perform. The ramp will rise when the pump is working.The lip will expend immediately when the ramp cylinder finishes its stroke. The ramp cylinder will retract when the pump stops operating. An emergency prevent is going to be recognized when the solenoid valve is energized. The decreasing speed of the two the ramp as well as lip is adjusted through the needle valves within the method.
Energy UNITS FOR DOCK LEVELER three
General Description
This 
Dock leveler energy unit basically raised the ramp once the motor is activated, once the ramp has reached full extension the sequence shifts to extend the lip. The ramp and lip are lowered by separate solenoid valves when the descent. The two the ramp and lip f of each functions are controlled by a needle valve. The needle valves are adjustable to accomplish the desired descent velocity of each function. The 2nd relief valve guarantees the primary platform to become floating under load when the dock leveler is being used for loading and unloading the products, therefore protecting the dock leveler properly.
