Vertical hydraulic Jack, Jack hydraulic, Jack

Product Introduction: Jack is a lifting tool commonly used in production. QYL type vertical oil Jack is a new series of national finalized products. It has simple structure, convenient operation, small volume, light weight and easy repair. It is widely applicable to the lifting operations of the annual warehouse, Bridge, wharf, transportation construction engineering and other departments of the factory. This product can only be used upright, and its working environment temperature is-20 celsius degree to+45 celsius degree, not suitable for use in acid and alkali and corrosive gases.

Working principle:

Oil Jack works according to the principle of Pasca's law. It consists of oil tank, two pressure cylinders of different sizes, rocker and closing pin valve. When working, lift the small piston to suck the oil into the small pressure cylinder, and when pressing down the small piston, press the oil into the large pressure cylinder. Through the control of the two valves, the pressure of the small piston to the oil is transmitted to the large piston to lift the heavy objects. The small piston keeps reciprocating and moving, and the weight can be lifted to a certain height. After the work is finished, open and close the pin valve to connect the large pressure oil cylinder with the oil tank. At this time, as long as there is a little pressure on the big piston, the big piston can fall and the oil will return to the fuel tank.
