Product Features

It is made of high-strength high-quality aluminum alloy material, with the advantages of beautiful shape, small size, light weight, stable lifting, safety and reliability. It has excellent stability, flexible operation and convenient promotion. Its light appearance can exert the highest lifting capacity in a very small space. Working principle The hydraulic oil is formed by a vane pump to form a certain pressure, and enters the lower end of the hydraulic cylinder through the oil filter, flameproof electromagnetic reversing valve, throttle valve, hydraulic control check valve, and balance valve, so that the piston of the hydraulic cylinder moves upward to lift heavy objects. The return oil at the upper end of the hydraulic cylinder returns to the oil tank through the flameproof electromagnetic reversing valve. Its rated pressure is adjusted by the overflow valve, and the pressure gauge reading is observed through the pressure gauge.The piston of the hydraulic cylinder moves downward (i.e. 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 hydraulic cylinder returns to the oil tank through the balance valve, hydraulic control one-way valve, throttle valve, and explosion-proof electromagnetic reversing valve. In order to make the heavy objects descend smoothly and brake safely and reliably, a balance valve is set on the return oil line to balance the circuit and maintain the pressure so that the descending speed is not affected by the weight. The throttle valve adjusts the flow and controls the lifting speed. In order to make the braking safe and reliable and prevent accidents, a hydraulic control one-way valve, i.e. a hydraulic lock, is added to ensure that it can be safely self-locked when the hydraulic pipeline bu.
