History of Hydraulic Jacks

Hydraulic jacks are widely used all across the globe. They have a lot of relevance in the present era, as they have made an incredible contribution in making our life much more comfortable than it was before. These jacks have outweighed conventional screw jacks that were in use at some point of time. They consist of two cylinders joined together. It works on the principle of Pascal’s law which suggests that when there is an increase in pressure at any point in a container of fluid, there is an equal increase in pressure at every other point in the container.


The origin of hydraulic jacks can be dated several years ago when Richard Dudgeon, the owner and inventor of hydraulic jacks, started a machine shop. In the year 1851, he was granted a patent for his hydraulic jack. In the year 1855, he literally amazed onlookers in New York when he drove from his abode to his place of work in a steam carriage. It produced a very weird noise that disturbed the horses and so its usage was limited to a single street. Richard made a claim that his invention had the power to carry near about 10 people on a single barrel of anthracite coal at a speed of 14 m.p.h. Dudgeon deserves a special credit for his innumerable inventions including the roller boiler tube expanders, filter press jacks, pulling jacks, heavy plate hydraulic hole punches and various kinds of lifting jacks.
