Specific Notes
one. The energy unit is of S3 duty, which could only be worked intermittently,i.e. 1minute on and 9 minutes off.
2. Clean all the hydraulic parts concerned prior to installation of the electrical power unit.
3. Viscosity in the hydraulic oil shoud be 15~46 cst, which really should also be clean and no cost of impurities, N46 hydraulic oil is advised .
four. Check the oil level in the tank soon after the initial operation of the energy unit.
5. Oil modifying is required right after the original one hundred operation hrs, afterwards when just about every 3000 hrs.
Power UNITS FOR DOCK LEVELER four
General Description
This power unit is deigned for those dock levellers which want floating ramps with an emergency halt function. The ramp will rise when the pump is running.The lip will expend immediately once the ramp cylinder finishes its stroke. The ramp cylinder will retract once the pump stops running. An emergency quit are going to be realized although the solenoid valve is energized. The reducing pace of the two the ramp as well as lip is 
adjusted through the needle valves during the procedure.
Power UNITS FOR DOCK LEVELER three
General Description
This Dock leveler power unit merely raised the ramp when the motor is activated, once the ramp has reached full extension the sequence shifts to lengthen the lip. The ramp and lip are lowered by separate solenoid valves although the descent. Each the ramp and lip f of each functions are managed by a needle valve. The needle valves are adjustable to attain the desired descent pace of every function. The 2nd relief valve ensures the main platform to get floating below load once the dock leveler is getting used for loading and unloading the goods, so protecting the dock leveler correctly.
