Although there are many types of jacks such as scissor, hi-lift and motor cycle jacks but hydraulic jack Singapore exists in mainly two forms i.e. floor jacks and bottle jacks. In a floor jack, also known as trolley jack, a horizontal piston pushes on the short end of a bell crank with the long arm which provides vertical movement to the lifting pad.
Floor jacks are easy to maneuver as they have wheels and coasters and are operated by wheeling and sliding the jack under the car. While in bottle jack instead of a lift arm, like in trolley jack, it has a single lift rod, which acts as a piston. With simple pumping of arm of jack, the piston can be raised.
