Quantitative Design Analysis of an Electric Scissor Lift

Abstract

In the industry, as a lifting system, the electrical scissor lift system is commonly used. this system is mainly preferred to do Load lifting and lowering activities, cleaning services, and maintenance-repair activities. In this paper, quantitative design analysis of several principal components of an electric scissor lift will be undertaken. A brushless dc geared-motor will be used to drive the rear wheels of the vehicle within an industrial area with front-wheel steering. The scissor lift will be operated via a motor-ballscrew arrangement. A systematic and detailed evaluation of the design will be carried out with paying particular attention to several aspects such as actuator selection for wheel drive unit and lift motion, quantitative design of the wheel drive gearbox, gearbox bearing selection, qualitative design of scissor lift and ballscrew unit selection, stress analysis of scissor pin joints and ballscrew connections, and vehicle power requirements and the motor control.
