Special Notes
1. The energy unit is of S3 duty, which could only be worked intermittently,i.e. 1minute on and 9 minutes off.
two. Clean all of the hydraulic components concerned in advance of installation of the energy unit.
three. Viscosity in the hydraulic oil shoud be 15~46 cst, which should really also be clean and no cost of impurities, N46 hydraulic oil 
is proposed .
four. Check the oil degree from the tank immediately after the original operation from the electrical power unit.
five. Oil changing is needed just after the original 100 operation hrs, afterwards when each 3000 hours.
Power UNITS FOR DOCK LEVELER four
Common Description
This power unit is deigned for all those dock levellers which need to have floating ramps with an emergency quit function. The ramp will rise when the pump is working.The lip will expend automatically once the ramp cylinder finishes its stroke. The ramp cylinder will retract once the pump stops running. An emergency prevent will probably be recognized while the solenoid valve is energized. The reducing speed of both the ramp and the lip is adjusted from the needle valves inside the procedure.
Power UNITS FOR DOCK LEVELER 3
Basic Description
This Dock leveler power unit simply just raised the ramp when the motor is activated, when the ramp has reached complete extension the sequence shifts to lengthen the lip. The ramp and lip are lowered by separate solenoid valves though the descent. Each the ramp and lip f of each functions are controlled by a needle valve. The needle valves are adjustable to attain the desired descent velocity of every perform. The 2nd relief valve assures the principle platform to become floating below load once the dock leveler is being used for loading and unloading the items, hence safeguarding the dock leveler correctly.
