Description of a lift enabling people who use a wheelchair to access objects at ground level. Developed at the Mechanical and Aerospace Engineering Department of The State University of New York at Buffalo, the device utilizes a scissor mechanism to raise and lower the lift. The scissors allow for a fully collapsible lift, so that at the lowest height the users will be able to slide themselves onto the floor. The frame is made up of steel square tubing. The tracks supporting the movement of the scissor arms are standard steel angle irons. The arms are powered by a threaded rod which is turned by manually cranking a ratchet attached on one end. A plastic chair is mounted on top of the lift. Plastic casters are mounted onto the side of the base to allow for easy transport. The handle of the ratchet is extendable to lower the force needed to turn the threaded rod. The maximum operable height of the lift is 25 inches; the lowest is 7 inches. Total weight of the lift is circa 55 pounds. Production cost was $253.
