A bottle jack is a mechanical lifting device used to lift and support heavy objects in industrial and commercial settings. It consists of a large cylindrical body, a piston, a handle, and a platform on which items can be placed. The handle is used to pump the piston, which raises the platform and its contents.
Bottle jacks are commonly used for lifting and supporting automotive vehicles, machinery components, and other heavy objects. They are often used in repair shops and industrial workshops, as well as for home improvement tasks.
