Particular Notes
one. The power unit is of S3 duty, which might only be worked intermittently,i.e. 1minute on and 
9 minutes off.
two. Clean each of the hydraulic parts concerned before installation of the electrical power unit.
three. Viscosity with the hydraulic oil shoud be 15~46 cst, which should also be clean and free of impurities, N46 hydraulic oil is advisable .
four. Check the oil level while in the tank immediately after the original operation with the power unit.
five. Oil modifying is required soon after the initial 100 operation hours, afterwards the moment every 3000 hours.
Electrical power UNITS FOR DOCK LEVELER four
Basic Description
This energy unit is deigned for anyone dock levellers which want floating ramps with an emergency stop function. The ramp will rise once the pump is operating.The lip will expend instantly once the ramp cylinder finishes its stroke. The ramp cylinder will retract when the pump stops working. An emergency prevent is going to be recognized although the solenoid valve is energized. The reducing velocity of both the ramp and also the lip is adjusted through the needle valves within the process.
Electrical power UNITS FOR DOCK LEVELER three
General Description
This Dock leveler power unit basically raised the ramp once the motor is activated, when the ramp has reached complete extension the sequence shifts to extend the lip. The ramp and lip are lowered by separate solenoid valves when the descent. The two the ramp and lip f of each functions are controlled by a needle valve. The needle valves are adjustable to attain the wanted descent velocity of every function. The 2nd relief valve guarantees the principle platform to become floating beneath load once the dock leveler is being used for loading and unloading the goods, therefore protecting the dock leveler effectively.
