The document describes the initial design of a portable automotive hoist called the MI'TY LIFTS by a group of students. It aims to create a hoist that can safely lift vehicles up to 6000 lbs to a maximum height of 48 inches for home mechanics. The design process included dividing design tasks among group members, considering different design options, and planning for future improvements.
