Specific Notes
1. The power unit is of S3 duty, which might only be worked intermittently,i.e. 1minute on and 9 minutes off.
2. Clean all of the hydraulic elements concerned prior to set up of the power unit.
3. Viscosity of your hydraulic oil shoud be 15~46 cst, which need to also be clean and cost-free of impurities, N46 hydraulic oil is advised .
four. Check the oil degree within the tank soon after the initial operation from the power unit.
5. Oil modifying is needed after the initial 100 operation hrs, afterwards when just about every 3000 hours.
Electrical power UNITS FOR DOCK LEVELER 4
Common Description
This energy unit is deigned for all those dock levellers which need floating ramps with an emergency quit function. The ramp will rise when the pump is running.The lip will expend instantly once the ramp cylinder finishes its stroke. The ramp cylinder will retract once the pump stops operating. An emergency halt might be realized whilst the solenoid valve is energized. The lowering speed of each the ramp as well as lip is adjusted through the needle valves inside the system.
Energy UNITS FOR DOCK LEVELER three
Common Description
This Dock leveler power unit simply raised the ramp when the motor is activated, once the ramp has reached total extension the sequence shifts to lengthen the lip. The ramp and lip are lowered by separate solenoid valves even though the descent. The two the ramp and lip f of every functions are managed by a needle valve. The needle valves are adjustable to 
attain the wanted descent speed of each function. The 2nd relief valve guarantees the primary platform to get floating beneath load once the dock leveler is getting used for loading and unloading the products, thus guarding the dock leveler efficiently.
