Final Report

Problem Statement

This project was designed to safely move heavy objects up and down stairs with very little hassle. We used a sled-type system with a hand cranking winch to safely move the weight up and down the stairs. The winch was rated for 500 pounds and we calculated that it could potentially pull up to 300 pounds at a maintained minimum safety factor of 2. The main goals of this project were to make sure that someone could safely load the heavy object onto the sled, ensure that they would be out of the danger zone before lowering it, portable, making sure that it operated correctly and worked, as well as that it was green and did not use any electricity and was human powered.
