Limitations of Mechanical jack:

In spite of many advantages we came up with few drawbacks due to which we have switched out topic to 

other type of jacking system. They are as follows:

Ø  Major modification involved

Ø  Higher cost

Ø  Lack of idea among common people

Ø  Maintenance is more

Ø  Parts are not available easily

Working of Mechanical jack.

This jack will employ two levers which will be used to lift the car. Jack will be mounted just ahead to the tires

at a lower portion of the car where maximum lift can be expected. It will take the power from the drive shaft

through a set of worm gear. When the car is stuck, worm gear will come in operating condition through the

use of two levers and this gear will then transfer the movement to the jack which will lift the car.

Mechanical jack:

This is not a simple traditional jack as we get in a car kit but our group has together tried to invent a new 

idea. Cars are very prone to get stuck in the deserts and to overcome it we need some new technology. This 

jack will take the power from drive shaft and will lift the car in the deserts without wasting human energy. It 

will be operated through a dashboard by a driver. It will be user friendly and effective method to recover 

cars from the deserts.
