The hydraulic jack is a lifting equipment used to facilitate the handling of heavy loads. It is commonly used in the automotive industry to lift vehicles.
How do hydraulic jacks work?
Hydraulic jacks are based on a simple working principle: they operate thanks to the actuation by a manual pump of a hydraulic cylinder, to lift the load. The lowering of the cylinder is ensured by the opening of a valve.
Types of hydraulic jacks
There are two main types of hydraulic jacks: bottle jacks and floor jacks.
The floor jack
The floor jack consists of a hydraulic cylinder, a rigid frame fitted with wheels and an articulated arm which provides the motion for lifting. The cylinder is actuated by a manual pumping motion via a handle.
Most floor jacks have a load capacity ranging from 2 to 5 tons, with some suitable for heavier loads and being able to lift up to 20 tons. Hydraulic floor jacks are therefore widely used in workshops.
The main advantage of this type of lifting jack lies in its ease of handling and movement thanks to its wheels. Heavy and stable, the floor jack is particularly suitable for mechanics.
The bottle jack
Bottle jacks and floor jacks are based on the same working principle. However, in the case of the bottle jack, the hydraulic cylinder is not mounted on a wheeled chassis, but on a fixed and flat support. The cylinder then performs the lifting directly, allowing much higher load capacities, up to 100 tons.
