Hydraulic press

A hydraulic press is a mechanical machine used for lifting or compressing large items. The force is generated through the use of hydraulics to increase the power of a standard mechanical level. This type of machine is typically found in a manufacturing environment. 

Invented in 1795 by Joseph Braham, the hydraulic press is also known as the Braham press. He used his knowledge of fluid mechanics and motion to develop this device. This invention significantly increased the compression power. By applying hydraulics to a press, an entire class of machines was invented. 

There is a wide range of different hydraulic press machines, ranging from small table top units for hobbyists to huge machines used to create metal parts. 

The primary concept used to provide power to the hydraulic press is that the level of pressure in a closed system is constant. This type of press has pistons with a fluid inside that is displaced by the pistons' inward movement. The fluid forces its way back into the space by moving the piston outward. The additional power is created through the movement of the fluid, which is confined to the system.
