FABRICATION & ANALYSIS OF MECHANICALLY OPERATED ROTATIONAL SCISSORS LIF

Abstract

This project describes the information about fabrication of a simple mechanical rotational scissor lift. Conventionally
a scissor lift or jack is used for lifting heavy loads with less effort mainly in industries or any other fields where loads
are lifted. It can be of mechanical, pneumatic or hydraulic type. The matter described in the paper is developed
keeping in mind that the lift can be operated by mechanical means so that effort required to operate is less for lifting
more weight. Also such design can make the lift more compact and much suitable for medium scale work. In our
project we added a feature of rotating the Scissor lift top table. This paper also gives information on how scissor lift
works with different means (ex-mechanical, pneumatic and hydraulic), basic information about worm, rack and
pinion, types of lifts, advantages of the scissor lift, different types of gears, gear nomenclature ,threads and scissor
arms.
