Case Study on Design & Analysis of Scissor Lift


The scissors lift is an elevator with a system of levers and hydraulic cylinders on which the metal platform is capable of moving in the vertical plane. This is achieved by using linked, folding supports in a criss-cross “X” pattern, called scissor mechanism.

The need for the utilization of elevators is incredibly wide and it runs across workshops, factories, labs, fixing of billboards, residential/commercial buildings to repair street lights, etc.
