When working, the small piston is lifted to suck the oil into the small pressure oil cylinder, and the oil pressure is pressed into the large pressure cylinder when the small piston is pressed. Through the control of the two valves, the small piston to the oil pressure to the large piston, the top of the heavy. The small piston can move back and forth to a certain height. After work, turn off the valve, high pressure cylinder communicated with the fuel tank. At this time, as long as a little pressure on the big piston, big piston can drop, oil back to the tank to go.
