Hydraulic Jack Types & Their Applications

Hydraulic jacks are mechanical devices that can lift heavy loads by applying force to the piston. Hydraulic jacks are typically employed in the automotive industry to raise vehicles off the ground. There are two kinds of hydraulic jacks: trolleys and bottle Jacks. Both types of jacks fulfil similar functions but differ in operation and design.

Pascal’s law can be used to determine the force exerted by the hydraulic jack. Two pistons within the cylinder, which are used for lifting heavy objects, are what hydraulic jacks are made of. The larger cylinder and the smaller cylinder are joined. The smaller piston can push the fluid upwards to raise the larger piston. The two ball valves function as a check valve, which permits flow to stop and stops while pumping.

Floor Jack

The shaft of the floor jack operates horizontally. If the handle is pushed downwards, it is lifted to lift the object upwards. There are two kinds of floor jacks. One is a mechanical floor jack, while the hydraulic one is a floor jack. The primary benefit of floor jacks is that they can be seated at a low level and work quickly.

  • Mechanical Floor Jack: This kind of floor jack has been designed with a screw mechanism. The screw mechanism works to raise the weight.
  • Hydraulic Floor Jack: The type described above is designed with Check valves, Cylinders, and pistons, which assist in lifting the weight.

Pancake Jack

The pancake hydraulic jack, sometimes called a low-profile hydraulic jack, is a unique hydraulic jack made with a compact and flat profile. In contrast to traditional hydraulic jacks with a higher and more cylindrical design, they are horizontally oriented and possess the lowest height relative to their lift capacity.

Bottle Jack

The name”bottle jack” derives from its appearance as an empty milk bottle. It lifts weight using an upright shaft driven through a lever. Bottle jacks are widely employed in the automotive industry to steal cars. They are secured with a frame and can be used as a freestanding piece of equipment that allows repositioning. One of the primary benefits of a bottle jack is its ability to fit into small spaces and places.

Hi-Lift Jack

Hi-Lift Jacks are often utilized for farm vehicles instead of cars or trucks. Hi-Life Jacks were developed by the Bloomfield Manufacturing Company 100+ years ago. There are two pins to climb that function differently from the Hi-Jack lift. One pin is used to hold the load while the other is released and moved to the next one as it is lifted. This kind of jack is dangerous if you need to learn how to use it properly. Please consult a professional before making use of it.

Trolley Jack

The Trolley Jack was created to raise a vehicle so that workers could access it underneath for repairs or regular maintenance. A trolley’s wheels perform small movements to compensate for the car’s weight distribution shift.

Hydraulic jacks have many applications and can be utilized in various ways, whether changing tires, lifting your vehicle up to inspect beneath for maintenance or repairs, or lifting heavy equipment to make repairs. A hydraulic jack enables users to apply immense force and power with a tiny, easy movement, simplifying your next mechanical task.
