Design and Fabrication of Mechanical Scissors Lifter

Lift is a simple mechanical device used to raise element or object from ground level to a certain height to perform a specific work with maximum load and minimum efforts. This project describes the design as well as analysis of a mechanical scissor lift which works on the principle of screw jack. The design will be developed keeping in mind that the lift can be operated by mechanical means so that the overall cost of the scissor lift is reduced. Also such design can make the lift more compact and much suitable for medium scale work. Conventionally a scissor lift or jack is used for lifting a vehicle to change a tire, to gain access to go to the underside of the vehicle, to lift the body to appreciableheight, and many other applications. But in this case along with lifting a vehicle we are also going to make an effort to move the vehicle to a short distance by incorporating roller mechanism. Finally, the analysis will be carried out in order to check the compatibility of the design values
