First, the hydraulic power unit is fixed in an appropriate position.
Second, with fittings connecting thread for the main valve plate: M16 * 1.5. Plus a few links are coupled two cylinder port rise and fall of oil port, using a high pressure hose coupled thereto.
Third, the fuel tank is filled with hydraulic oils (summer 46 #, 23 # in winter).
Fourth, the power coupling. Motor 380V, three-way solenoid valve 24V.
 
Course of action
 
First, the rising or before acting as
Start the motor, the three-way solenoid valve solenoid coil is energized to control the rise side, until the desired increase in height. Motors, solenoid valves de-energized, the fuel tank in a raised position, was packing state.
 
Second, the decline or back action
Off the motor is energized, the other end of the three-way solenoid valve is energized, the fuel tank to achieve fall, until the desired position. Motors, solenoid valve power, the action is completed.
 
Third, the traveling speed adjustment
Under the three-way solenoid valve is a two-way flow control valve, for adjusting the speed, rotating handle, positive spin to slow down. On the contrary, accelerated.
