A hydraulic bottle jack is a compact, portable lifting tool used to raise heavy objects, particularly vehicles, using hydraulic pressure. They are commonly used for tire changes, repairs, and supporting structures or machinery. 
 

Here’s a more detailed explanation:
 

The jack uses pressurized hydraulic fluid to lift the load, allowing for powerful lifting with minimal effort. 
 

Unlike floor jacks, bottle jacks are designed for vertical lifting and are ideal for situations where space is limited. 
 

Their small size makes them easy to store and transport, making them useful for both professional and DIY use. 
 

Applications:
 

Automotive Industry: Lifting vehicles for maintenance and repairs, tire changes, and accessing undercarriage components. 
 

Construction: Supporting heavy structures during construction and lifting heavy equipment. 
 

Industrial Applications: Lifting machinery, equipment, and other heavy objects in various industrial settings.
