Exclusive Notes
one. The energy unit is of S3 duty, which can only be worked intermittently,i.e. 1minute on and 9 minutes off.
2. Clean all of the hydraulic parts concerned ahead of set up of the power unit.
three. Viscosity with the hydraulic oil shoud be 15~46 cst, which should really also be clean and free of impurities, N46 hydraulic oil is advisable .
four. Check the oil degree within the tank immediately after the preliminary operation from the electrical power unit.
5. Oil shifting is required soon after the initial one hundred operation hrs, afterwards after every 3000 hrs.
Energy UNITS FOR DOCK LEVELER 4
Common Description
This energy unit is deigned for all those dock levellers which need to have floating ramps with an emergency prevent function. The ramp will rise when the pump is operating.The lip will expend immediately when the ramp cylinder finishes its stroke. The ramp cylinder will retract once the pump stops operating. An emergency end will be realized even though the solenoid valve is energized. The decreasing pace of both the ramp and the lip is adjusted by the needle valves in the method.
Power UNITS FOR DOCK LEVELER 3
Common Description
This Dock leveler energy unit just raised the ramp when 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 even though the descent. Each the ramp and lip f of each functions are managed by a needle valve. The needle valves are adjustable to realize 
the preferred descent pace of every function. The 2nd relief valve guarantees the main platform to get floating beneath load once the dock leveler is being used for loading and unloading the items, thus guarding the dock leveler effectively.
