Design of stair climbing cart mechanism for heavy load lifting

Abstract

This study presents the design of a stair climbing cart to address the problem of lifting the heavy goods up to the stairs conveniently. A detailed design, mechanism and its analysis are presented. Design may be cost effective and affordable compared to human efforts for lifting the objects up to the stairs particularly for heavy loads. It works for a range of steps with step size range of less than 16 cm in height. Our proposed design and its characterisation ensure its functioning in any environmental conditions (such as dusty surface, etc.) and also on tiles/frictionless surface.
