Rao, Pratap M.
This MQP presents a solution to the time consuming and expensive process of snow removal. Eleven initial designs were generated and analyzed in terms of forces, weight, cost, safety, energy efficiency, storage/installation and internal forces. Finally a cable guided shovel design was selected for further analysis, design refinement and prototyping. The final design consists of a shovel that is driven along taut cables fixed parallel to the path to be cleared. The cables pass through either side of the shovel and through a motor- pulley assembly mounted to the shovel. Opposing frictional forces on the shovel blade and cable were determined to size the motors and cable. A prototype device was assembled to test its performance using mulch as the substitute for snow.
