Jacks are portable devices used for raising heavy objects by means of force applied with a lever or screw. The hydraulic jacks are compact and lightweight units that are used for lifting capacities. They offer easy operation and are fast acting components. The hydraulic jacks come with inbuilt release pedal for rapid lowering and lugs that make it easy to mount. The heavy duty chassis prevents the jack from twisting or bending and foot pump provides fast lift to the load. It also has a safety overload valve that prevents overloading beyond rated capacity.

Features of Hydraulic Jacks

The hydraulic jack is designed with a super low-clearance combined with the unique total lift offering range that one needs ever. Together with the quick-lift pedal, the hydraulic jacks are suited for heavy duty intensive and commercial use. Hydraulic jack manufacturers are producing jacks with extra wide stance for extra stability, complete air operation for low maintenance and long life.

The jacks have a longer wear life due to internally machined oil passages, smooth bearing surfaces and close tolerances. The cold headed extension screw and release valve eliminate parts and reduce the chances of breakage and excessive wear.

Types of Hydraulic Jacks

There are two main types of hydraulic jacks. Bottle Jack: The bottle jack in which the piston is vertical. It is suitable only for vehicles.

Floor Jack: There is the floor hydraulic jack, having a horizontal piston. This type is helpful for easy maneuvering underneath the vehicle, while offering considerable extension.

Working of Hydraulic Jacks

A hydraulic jack operates using a fluid, that is forced into a cylinder by a pump plunger. Oil is used because of its self lubricating nature. When the plunger is pulled back, oil is drawn out of the reservoir with the help of a suction check valve into the pump chamber. When the plunger moves forward, oil is pushed into the cylinder. The suction valve ball which is located inside the chamber and opens when the plunger is drawn. On the other hand, the discharge valve ball is outside the chamber and this opens when the oil enters into the cylinder. At this point the suction ball is forced shut and oil pressure builds in the cylinder.
