Screw Jack

A screw jack, also known as a mechanical jack or a worm gear jack, is a mechanical device used for lifting heavy loads or applying controlled pressure. It operates based on the principle of a screw mechanism and is commonly used in various applications, including automotive repairs, construction, and industrial settings.The screw jack consists of a threaded screw mechanism enclosed within a housing. It typically has a handle or a lever for turning the screw. As the screw is rotated, it moves linearly, exerting force to raise or lower the load supported by the jack.Screw jacks are available in different designs and load capacities to suit various requirements. They can be manual or electrically powered, with manual screw jacks being operated by hand, while electric versions utilize an electric motor for automated lifting.The advantage of a screw jack is its ability to provide precise and controlled vertical movement or pressure application. The pitch of the screw thread determines the lifting speed and the load capacity of the jack. Screw jacks find applications in scenarios where heavy objects need to be lifted, supported, or positioned accurately. They offer a reliable and efficient solution for tasks that require controlled vertical movement or pressure application, making them widely used in various industries.
