Fabrication of Hydraulic Scissor Lift

Abstract

This report focused on force acting on the hydraulic scissor lift when it is extended and contracted. Generally, a hydraulic scissor lift is used for lifting. Material selection plays a key role in designing a machine and also influence on several factor such as durability, reliability, strength, resistance which finally leads to increase the life of scissor lift. The following project describes the fabrication of a hydraulic scissor lift. Conventionally a scissor lift is used for lifting the body to appreciable height, and many other applications also such lifts can be used for various purposes like maintenance and many material handling operations. It can be of mechanical, pneumatic or hydraulic type. The design described in the report is developed by keeping in mind that the lift can be operated by mechanical means by using pantograph shaped scissor, so that the overall cost of the scissor lift is reduced. The upward motion is achieved by the application of hydraulic cylinder which is placed vertically. In our case upward motion of the lift was to be designed in a portable manner and also which works without consuming any electric power so we decided to use a hydraulic cylinder.
