Vertical hydraulic jack is commonly used in the production of a lifting tool. Its simple structure, convenient operation, repair cars, tractors and other commonly used it from the top body, easy to repair. Hydraulic jacks are based on the principle of Pascal's law work. It consists of the fuel tank, two pressure cylinders of different sizes, joystick, and close the needle valve and several other components. Work, the mention of a small suction pressure of the oil piston cylinder when the piston when the hydraulic pressure into the small large pressure tank. Controlled by two valves, a small piston on the oil pressure is passed to the large piston, the top weight up. Small piston moves back and forth constantly, you can put the top weight to a certain height. Work is completed, close the valve open, so that large pressure tanks and tank connected. At this time, as long as the pressure a little on the large piston large piston to fall, the oil back to tank. QYL vertical hydraulic jack is a new series of national stereotypes. It is compact, small size, light weight, portable, widely used in factories in warehouses, bridges, terminals, transportation and construction sectors such as lifting. This product can only be used upright, its working temperature of -20 degrees Celsius to +45 degrees Celsius, pH and corrosive gases should not be in use. 
 Vertical hydraulic jack compact, small size, light weight, easy to carry, vertical hydraulic jacks are widely used in factories, warehouses, bridges, docks, transportation and construction sectors such as lifting.
