The hydraulic systems use the energy of the liquid fluid to do a simple job, operated by the use of hydraulic systems, where a liquid is the means of feeding. Heavy equipment is a common example. In this type of machine, the hydraulic fluid is transmitted through the machine to several hydraulic motors and hydraulic cylinders and is pressurized according to the present resistance.

Hydraulic systems, like pneumatic systems, are based on Pascal's law that states that any pressure applied to a fluid within a closed system will transmit that pressure equally everywhere and in all directions. A hydraulic system uses an incompressible liquid as its fluid, instead of a compressible gas.

Joseph Bramah patented the hydraulic press in 1795. While working at the Bramah store, Henry Maudslay suggested a leather package for the cup. Because it produced superior results, the hydraulic press eventually displaced the steam hammer from the metal forge.


Hydraulic systems of the central station were developed to provide small-scale power that was not practical for individual steam engines. Hydraulic power was used to operate cranes and other machines in British ports and elsewhere in Europe. 

The largest hydraulic system was in London. Hydraulic power was widely used in the production of Bessemer steel. Hydraulic power was also used for elevators, to operate channel locks and rotating sections of bridges. Some of these systems remained in use until well into the 20th century.
