Abstract:
Scissor jacks are simple mechanisms used to drive large loads for short distances. The power screw design of common scissor jack reduces the amount of force required by the user to drive the mechanism. Most scissor jacks are similar in design, consisting of four main members driven by a power screw. In this report, a unique design of a scissor jack is proposed which is very easy to manufacture. Each member, including the power screw sleeves, is made of the common c-shape. This eliminates the need for machined power screw sleeves, which connect the four members and the power screw together. The manufacturability of the proposed scissor jack lowers the cost of production. Scissor jacks allow to raise heavy loads using only a fraction of the force ordinarily needed. In this project the effort was to design an efficient Electric scissor Jack to be operated by Electric Power of carsâ„¢ own battery & capable of raising a 1600 lbs load.
