Basic Introduction to Jacks
A jack, a lightweight lifting device no more than 1 meter in height, uses a rigid lifting component as its core, easily lifting heavy objects within a specific stroke via a top support or bottom claw. It is divided into two main categories: mechanical and hydraulic. It is widely used in vehicle repair in factories, mines, transportation, and other fields, as well as in other lifting or support applications. Its structure is compact and durable, easily carried and operated by a single person.
A jack is a portable lifting device that lifts heavy objects within a specific stroke via a top support or bottom claw, primarily used for vehicle repair and other lifting applications.
Mechanical Jacks
Jacks are mainly divided into two categories: mechanical and hydraulic. Each has its own principles. Mechanical jacks are operated via a handle, utilizing mechanical principles to lift, but require multiple operations and are relatively complex. By repeatedly turning the handle, the claw pushes the ratchet to rotate. This action drives the small bevel gear, which in turn causes the large bevel gear and the lifting screw to rotate. In this way, the lifting sleeve can be raised or lowered, thereby generating lifting force.
