one. The power unit is of S3 duty, which could 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 ought to also be clean and free of impurities, N46 hydraulic oil is advisable .
four. Check the oil level from the tank immediately after the original operation with the energy unit.
five. Oil modifying is needed soon after the initial 100 operation hours, afterwards the moment every 3000 hours.
Electrical power UNITS FOR DOCK LEVELER four
This energy unit is deigned for anyone dock levellers which need to have 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 once the pump stops working. An emergency stop might be recognized although the solenoid valve is energized. The reducing velocity of both the ramp as well as the lip is adjusted through the needle valves within the procedure.
Electrical power UNITS FOR DOCK LEVELER three
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 realize the wanted descent velocity of every function. The 2nd relief valve guarantees the main platform to become floating underneath load once the dock leveler is being used for loading and unloading the goods, therefore protecting the dock leveler successfully.
