Special Notes
1. The power unit is of S3 duty, which can only be worked intermittently,i.e. 1minute on and 9 minutes off.
two. Clean the many hydraulic parts concerned prior to installation of the power unit.
3. Viscosity of the hydraulic oil shoud be 15~46 cst, which should also be clean and free of charge of impurities, N46 hydraulic oil is advisable .
four. Check the oil level during the tank immediately after the initial operation with the energy unit.
5. Oil transforming is required just after the original one hundred operation hrs, afterwards once every 3000 hours.
Energy UNITS FOR DOCK LEVELER four
Basic Description
This electrical power unit is deigned for anyone dock levellers which will need floating ramps with an emergency stop function. The ramp will rise once the pump is working.The lip will expend instantly once the ramp cylinder finishes its stroke. The ramp cylinder will retract when the pump stops operating. An emergency prevent are going to be recognized when the solenoid valve is energized. The lowering speed of both the ramp along with the lip is adjusted from the needle valves while in the 
technique.
Power UNITS FOR DOCK LEVELER three
Common Description
This Dock leveler electrical power unit simply just raised the ramp once 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. Both the ramp and lip f of every functions are managed by a needle valve. The needle valves are adjustable to achieve the sought after descent velocity of each function. The 2nd relief valve assures the principle platform for being floating below load once the dock leveler is being used for loading and unloading the items, so defending the dock leveler correctly.
