Product Introduction: A jack is a commonly used lifting tool in production. The QYL type vertical hydraulic jack is a national standardized new series product. Its structure is simple, operation is convenient, and it is small and light, making it convenient for maintenance. It is widely used in lifting operations in various departments such as factories, warehouses, bridges, piers, and transportation construction projects. This product can only be used vertically, and its working environment temperature is -20°C to +45°C. It is not suitable for use in acidic and alkaline environments or corrosive gases.

Working Principle:

The hydraulic jack operates based on the principles of the Pascal's law. It consists of several parts including a tank, two pressure oil cylinders of different sizes, a rocking arm, and a closing needle valve. When working, the small piston sucks oil into the small pressure oil cylinder, and when pressing down on the small piston, the oil is pressed into the large pressure oil cylinder. The pressure of the oil on the small piston is transmitted to the large piston, allowing the heavy object to be lifted. The small piston continuously recursively acts, allowing the heavy object to be lifted to a certain height. After the work is completed, the closing needle valve is opened to connect the large pressure oil cylinder and the tank. At this time, as long as a slight pressure is applied to the large piston, it can fall, and the oil returns to the tank.
