ABSTRACT: In this hydraulic jack, load or pressure applied at one end leads to lifting of load at the other end. Load can be applied in two ways, one is by applying load on one 10ml Syringe and keeping other syringe at rest or closed due to which when a specific load is applied at one end specific load is lifted at other end. Another way is by continously pumping the 10ml syringe dipped in mug of water, due to which any load within range will be lifted.

INTRODUCTION: Hydraulic Jack: Hydraulic Jack is a device which is used to lift heavy vehicles by using hydraulic pressure. In 1838 William Joseph Curtis filed a British patent for a hydraulic jack. In 1851, inventor Richard Dudgeon was granted a patent for a "portable hydraulic press" - the hydraulic jack, a jack which proved to be vastly superior to the screw jacks in use at the time. Hydraulic jacks are typically used for shop work, rather than as an emergency jack to be carried with the vehicle. Use of jacks not designed for a specific vehicle requires more than the usual care in selecting ground conditions, the jacking point on a vehicle, and to ensure stability when the jack is extended. Hydraulic jacks are often used to lift elevators in low and medium rise buildings. A hydraulic jack uses a liquid, which is incompressible, that is forced into a cylinder by a pump plunger. Oil is

11

used since it is self lubricating and stable. When the plunger pulls back, it draws oil out of the reservoir through a suction check valve into the pump chamber. When the plunger moves forward, it pushes the oil through a discharge check valve into the cylinder. The suction valve ball is within the chamber and opens with each draw of the plunger. The discharge valve ball is outside the chamber and opens when the oil is pushed into the cylinder. At this point the suction ball within the chamber is forced shut and oil pressure builds in the cylinder. In a floor jack (aka 'trolley jack') a horizontal piston pushes on the short end of a bellcrank, with the long arm providing the vertical motion to a lifting pad, kept horizontal with a horizontal linkage. Floor jacks usually include castors and wheels, allowing compensation for the arc taken by the lifting pad. This mechanism provides a low profile when collapsed, for easy maneuvering underneath the vehicle, while allowing considerable extension.

CONCLUSION: From the above project we conclude that property of the fluid like pressure can be made use for lifting of heavy loads where conventional machines are inconvenient compared to hydraulic jack.
