Screw Jack Manufacturer
A screw jack is a mechanical device used to lift or lower heavy loads or to apply force in a linear motion using the principle of a screw thread. It typically consists of a threaded rod or screw, a supporting base, and a lifting mechanism such as a handle or motor. The threaded rod is inserted into a threaded nut, and when the rod is rotated, it moves through the nut, causing linear displacement of the load or applying force in a desired direction. Screw jacks are commonly used in various industrial and automotive applications, such as lifting vehicles, supporting structures, adjusting work tables or platforms, and providing linear actuation in machinery and equipment. They are known for their ability to provide mechanical advantage, precise positioning, and the capacity to handle heavy loads.

Screw Jack Working Principle
The working principle of a screw jack is based on the mechanical advantage gained from the rotation of a screw thread. The screw jack consists of three main components: a threaded screw, a threaded nut, and a handle or motor for applying the rotational force. Here’s a breakdown of how the screw jack works:
Threaded Screw
The screw jack features a long, threaded rod or screw with a helical thread running along its length. The thread profile can vary, with common options being square, trapezoidal, or acme threads. The screw is typically fixed to a stationary base or framework.
Threaded Nut
The threaded nut is a component that engages with the screw threads. It is usually a cylindrical or rectangular housing with internal threads that match the threads on the screw. The nut can move along the length of the screw when the screw is rotated.
Rotational Force
To operate the screw jack, a handle is typically attached to the screw or a motor is used to apply rotational force. When the handle or motor is turned, it rotates the screw, causing it to move through the stationary nut.
Linear Motion
As the screw rotates, the nut moves along the length of the screw in a linear direction. The pitch of the thread determines the distance the nut moves with each revolution of the screw. The direction of the linear motion depends on the direction of rotation of the screw.
