What is jackscrew?

A jackscrew is a mechanical device used to lift heavy loads or apply large forces. It consists of a screw mechanism that is turned to raise or lower a platform or object. The screw is typically attached to a handle or crank for easy turning.

Jackscrews are commonly used in automotive and construction industries, where they are used to raise cars, buildings, or other heavy objects. They are also used in mechanical engineering for precise positioning and alignment of components.

There are different types of jackscrews, including bottle jacks, scissor jacks, and screw jacks, each designed for specific applications. Bottle jacks are small and portable, while screw jacks are larger and used for heavier loads.

Overall, jackscrews are a simple yet effective tool for lifting and moving heavy objects with precision and control.
