Hydraulic Jack Lift – How Does It Work?

Hydraulic jack lift equipment proliferates in the stock and equipment rooms of so many industrial plants, building yards, construction sites and garages. This is because it allows for lifting of equipment that is heavy – anything from a five ton load to a 50 ton load. But how does it work?

Essentially, all hydraulic jacks work using the same principles. The main difference between the different hydraulic jacks and hydraulic lifting equipment is their size and shape. That being said, the actual utility of each of the hydraulic jacks, and their uses in certain situations, can very much vary. But these jacks generally consist of incompressible fluid being passed through two cylinders – usually a larger and a smaller one. The fluid was historically whiskey – due to its ability to persevere during harsh winter times – but these days it’s oil (to the delight of whiskey drinkers everywhere). Whatever the liquid used, it is pushed into one of the cylinders with the assistance of a piston pump. The pump can either be built internally or externally. The parts work together to fully utilise Pascal’s law – the principle of transmission of fluid-pressure (Pascal’s Principle). It states that pressure change occurring in confined incompressible fluid is transmitted through the fluid, such as oil, to enact changes everywhere within that confined environment. That pressure within the cylinder is then used to create the force to lift heavy loads. Different hydraulic jacks include bottle jacks, trolley jacks and the much-used toe jack.
