What is screw jack?

A screw jack, also known as a jackscrew, is a type of jack that is operated by turning a leadscrew. It is commonly used to lift moderately and heavy weights, such as vehicles; to raise and lower the horizontal stabilizers of aircraft; and as adjustable supports for heavy loads, such as the foundations of houses.

A screw jack consists of a heavy-duty vertical screw with a load table mounted on its top, which screws into a threaded hole in a stationary support frame with a wide base resting on the ground. A rotating collar on the head of the screw has holes into which the handle, a metal bar, fits. When the handle is turned clockwise, the screw moves further out of the base, lifting the load resting on the load table. To support large load forces, the screw is usually formed with Acme threads.

Screw jacks are available in a variety of sizes and capacities. The size of the jack is determined by the load that it is designed to lift. The power of the jack is determined by the amount of force that it can exert.

Screw jacks are a versatile and reliable tool that can be used for various lifting applications. They are easy to use and maintain, and they are available at a variety of price points.
