The remote controlled screw jack is a modified form of the commonly used screw jack. It uses motor as the energy source to lift the object and the gearbox is used to control the lift of the jack. In this project, the conventional motorised cylindrical lifting jack is modified by adding an additional ring in the centre for the purpose of gripping the v belt assembly. A v belt pulley is added at the output shaft of the 12v big DC motor. The entire structure and assembly is held in position by an angle iron based assembly. The entire project is ru ....etc

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 s ....etc
