Design and analysis of power screw for manhole cover lifter

Abstract

The importance of manhole in the sewerage system is to get the underground pipelines and alternative systems area unit in good shape. A manhole cover is a detachable plate setting the roof above the manhole opening, to prevent anything from dropping in, and to stay away from unauthorized persons and matter to fall in it. Manhole covers are usually manufactured of cast iron, concrete or combine both. This creates them economical, powerful, and dense, generally weighing more than 50 kg. The weight supports to maintain them in position when transportation moves across them and makes it complicated for an unauthorized person not having proper tools to remove them. The traditional method of removing the manhole with the assistance of the hook. So, to safely remove the manhole cover, many innovative and automated techniques are designed and used for analysis. In this paper, the finite element analysis of a power screw operated manhole cover is analyzed with the help of ANSYS R14.5.
