Whenever the tyre failure is occurred in the vehicle then to lifting the vehicle from ground surface is the very difficult thing for human being. And also huge human effort required and more time taking process. Though, this inbuilt hydraulic jack system helps to lift the vehicle from the ground level automatically instead of conventional mechanical jack, and saves the time and excess effort. It is fitted on the vehicle chassis. This inbuilt hydraulic technique can be quickly operated by automatic function buttons on the board panel of the vehicle. The arrangement of this technique are as follows, the hydraulic jack will be mounted near the suspension system of the vehicle. This jack will be very useful for all senior citizens, physically challenged persons and especially for females who find it extremely difficult to operate the jack manually in any breakdown condition.

Hydraulic cylinder, incompressible Hydraulic Oil, Pascal Law, Directional Control Valve.
