Particular Notes
1. The energy unit is of S3 duty, which may only be worked intermittently,i.e. 1minute on and 9 minutes off.
2. Clean every one of the hydraulic parts concerned prior to installation of the energy unit.
three. Viscosity of the hydraulic oil shoud be 15~46 cst, which should really also be clean and cost-free of impurities, N46 hydraulic oil is advisable .
4. Check the oil level from the tank just after the first operation from the power unit.
5. Oil changing is required just after the initial 100 operation hrs, afterwards once every 3000 hours.
Energy UNITS FOR DOCK LEVELER four
Common Description
This electrical power unit is deigned for all those dock levellers which have to have floating ramps with an emergency halt perform. The ramp will rise when the pump is working.The lip will expend immediately when the ramp cylinder finishes its stroke. The ramp cylinder will retract once the pump stops working. An emergency end is going to be realized while the solenoid valve is energized. The reducing velocity of both the ramp as well as the 
lip is adjusted by the needle valves inside the method.
Electrical power UNITS FOR DOCK LEVELER 3
Standard Description
This Dock leveler energy unit simply just raised the ramp when the motor is activated, when the ramp has reached full extension the sequence shifts to extend the lip. The ramp and lip are lowered by separate solenoid valves even though 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 pace of each function. The 2nd relief valve assures the primary platform to become floating beneath load when the dock leveler is getting used for loading and unloading the goods, thus protecting the dock leveler successfully.
