Working principle of construction lift:

The hydraulic oil forms a certain pressure by the vane pump and passes through the oil filter , explosion-proof electromagnetic reversing valve, throttle valve, hydraulic control check valve and balance valve enter the lower end of the liquid cylinder, causing the piston of the liquid cylinder to move upward to lift heavy objects, and the oil returned to the upper end of the liquid cylinder is reversed by the explosion-proof electromagnetic The valve returns to the tank, its rated pressure is adjusted through the relief valve, and the pressure gauge reading is observed through the pressure gauge.

The piston of the hydraulic cylinder moves downward (that is, the weight drops). The hydraulic oil enters the upper end of the hydraulic cylinder through the explosion-proof electromagnetic reversing valve, and the return oil from the lower end of the liquid cylinder returns to the tank through the balance valve, hydraulic control check valve, throttle valve, and explosion-proof electromagnetic reversing valve. In order to make the heavy objects fall smoothly and the braking to be safe and reliable, a balance valve is installed on the oil return line to balance the circuit and maintain the pressure so that the descending speed is not changed by the heavy objects. The throttle valve regulates the flow and controls the lifting speed. In order to make the brake safe and reliable and prevent accidents, a hydraulically controlled one-way valve, that is, a hydraulic lock, is added to ensure that it can lock itself safely when the hydraulic pipeline bursts unexpectedly. An overload acoustic alarm is installed to distinguish overloading or equipment failure.

The electrical control system uses explosion-proof buttons SB1-SB6 to control the rotation of the motor and the reversal of the explosion-proof electromagnetic reversing valve to keep the load rising or falling, and adjust the time delay through the "LOGO" program , to avoid frequent starting of the motor and affecting its service life.
