Product description

A jack is a light lifting device that uses a steel lifting member as a working device to lift a heavy object in the stroke through a top bracket or a bottom bracket.

A tool used to support blanks or irregular workpieces for scribing, usually in groups of three.

There are several kinds of jacks, such as mechanical jacks and hydraulic jacks. The principle is different. In principle, the basic principle based on hydraulic transmission is the Pascal principle. That is to say, the pressure of the liquid is consistent, so that the system is balanced. In the middle, the pressure exerted on the relatively small piston is relatively small, and the pressure exerted on the large piston is relatively large, so that the liquid can be kept 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 principle of the screw jack is to reciprocate the handle, the claw is to push the ratchet gap to rotate, the small bevel gear drives the large bevel gear, and the lifting screw rotates, so that the lifting sleeve can be lifted or lowered to achieve the lifting force. . But not as simple as a hydraulic jack.
