The jacks are divided into two types: Mechanical jacks and hydraulic jacks. 

The principles are different. In principle, the hydraulic jack is based on the Pascal principle, that is, the pressure across the liquid is uniform, so that in a balanced system, the pressure exerted on the smaller piston is smaller, while the larger piston is on the larger piston. The applied pressure is also relatively large, which keeps the liquid stationary. Therefore, by the transfer of the liquid, different pressures at different ends can be obtained, so that a transformation can be achieved. The hydraulic jacks we often use are using this principle to achieve force transmission.

The mechanical jack adopts the mechanical principle to reciprocate the handle, and the claw pulls the ratchet gap to rotate. The small bevel gear drives the large bevel gear to rotate the lifting screw, so that the lifting sleeve can be lifted or lowered to reach the lifting force. Features. But not as simple as a hydraulic jack._MG_8037
