Special Notes
one. The electrical power unit is of S3 duty, which can only be worked intermittently,i.e. 1minute on and 9 minutes off.
2. Clean all the hydraulic elements concerned before installation of the electrical power unit.
three. Viscosity in the hydraulic oil shoud be 15~46 cst, which must also be clean and absolutely free of impurities, N46 hydraulic oil is advisable .
4. Check the oil degree during the tank after the initial operation from the power unit.
five. Oil changing is required following the preliminary 100 operation hrs, afterwards once each and every 3000 hrs.

Energy UNITS FOR DOCK LEVELER four
Common Description
This electrical power unit is deigned for those dock levellers which need floating ramps with an emergency stop function. The ramp will rise once the pump is working.The lip will expend instantly when the ramp cylinder finishes its stroke. The ramp cylinder will retract once the pump stops working. An emergency stop will be realized though the solenoid valve is energized. The reducing velocity of each the ramp and also the lip is adjusted through the needle valves during the program.

Power UNITS FOR DOCK LEVELER 3
Standard Description
This Dock leveler electrical power unit just raised the ramp once the motor is activated, once the ramp has reached complete extension the sequence shifts to lengthen the lip. The ramp and lip are lowered by separate solenoid valves although the descent. The two the ramp and lip f of each functions are controlled by a needle valve. The needle valves are adjustable to achieve the desired descent speed of each function. The 2nd relief valve assures the primary platform for being floating underneath load once the dock leveler is getting used for loading and unloading the goods, therefore defending the dock leveler proficiently.
