Abstract— An Automatic jack can be easily operated by using of pneumatic cylinder which is operated by compressed air cylinder. The jack assembly will be mounted on both the sides of chassis according to the weight distributions of the car. Similarly it will be installed on the other side of the car. The system operates on pneumatic drive which consists of following main parts: Pneumatic cylinder, compressed air cylinder, bell crank liver to lift the vehicle. The bell crank liver actuate separately for either side of car as per the condition. The car gets lifted and load gets distributed on pivot of bell crank liver they guide by c-sec case. The cylinder pushes the bell crank liver under guide of c-section. This jack will be very useful for all the senior citizens and especially for females (ladies) who find it extremely difficult to operate the jack manually in any breakdown condition. As the hydraulic oil is incompressible so the lifting capacity is more in comparison with the pneumatic system which operates on air which is compressible.
