Particular Notes
1. The electrical power unit is of S3 duty, which could only be worked intermittently,i.e. 1minute on and 9 minutes off.
two. Clean all of the hydraulic components concerned prior to installation of the energy unit.
3. Viscosity from the hydraulic oil shoud be 15~46 cst, which must also be clean and absolutely free of impurities, N46 hydraulic oil is suggested .
4. Check the oil level within the tank right after the initial operation with the power unit.
five. Oil shifting is required following the first one hundred operation hours, afterwards when every single 3000 hours.
Electrical power UNITS FOR DOCK LEVELER 4
General Description
This electrical power unit is deigned for those dock levellers which want floating ramps with an emergency end function. The ramp will rise once the pump is operating.The lip will expend immediately once the ramp cylinder finishes its stroke. The ramp cylinder will retract once the pump stops operating. An emergency end are going to be recognized whilst the solenoid valve is energized. The decreasing speed of both the ramp and also the lip is adjusted from the needle valves inside the process.
Electrical power UNITS FOR DOCK LEVELER 3
Common Description
This Dock leveler power unit just raised the ramp once the motor is activated, once the ramp has reached complete extension the sequence shifts to extend the lip. The ramp and lip are lowered by separate solenoid valves whilst the descent. Both the ramp and lip f of each functions are controlled by a needle valve. The needle valves are adjustable to accomplish the sought after descent speed of every perform. The 2nd relief valve assures the main platform to be floating below load when 
the dock leveler is getting used for loading and unloading the products, consequently guarding the dock leveler effectively.
