Lifting capacity: Hydraulic ram jacks are available in various lifting capacities, ranging from a few tons to several tons. They are capable of lifting and supporting heavy loads safely and efficiently.

Hydraulic pressure: Hydraulic ram jacks utilize hydraulic fluid, typically oil, to generate lifting force. When pressure is applied to the hydraulic fluid, it transfers the force to a piston, which extends and raises the load. The hydraulic system allows for smooth and controlled lifting operations.

Compact and portable: Hydraulic ram jacks are designed to be compact and portable. They are often shaped like a bottle, hence the name "bottle jack." This design makes them easy to transport and store, and they can be used in various locations.
