| dc.description.abstract | A screw jack is a mechanical device used for lifting the heavy-duty vehicles. Screw
jack is employed by the screw threads for lifting purpose. To operate the screw the
handle is used and when the handle is operated clockwise then it lifts the work similarly
when the handle is operated in anti-clockwise then it lowers the work. In case of tire
flat or changing the tire, the screw jack is very important and useful device. The screw
jack is operated manually and when the ancient people when they want to change the
tire it is not so easy. So, to overcome the situation it can be employed automatically so
that the time is reduced and they can conveniently replace the tire. The motorized screw
jack features user-friendly controls, robust safety systems like automatic locks and
emergency shut-off functions, and is constructed from durable materials to ensure long
term reliability. It operates via a 12V power supply, typically sourced from a vehicle’s
cigarette lighter socket. The project demonstrates that the motorized screw jack can lift
a vehicle safely and efficiently, making it a valuable tool for both professional
mechanics and everyday vehicle owners. The prototype's performance in load tests
confirms its capability to handle substantial weights with improved lifting speed and
minimal manual effort. | en_US |
