Abstract
A ceiling mounted lift (200), of the type having a support frame (210) housing a drive mechanism (240) that operates to raise and lower a lifting platen (22) using a fabric drive roller (244), has a stabilizer (230), and is small enough to fit between standard ceiling joists. Preferred stabilizers have free movement in substantially only one plane and such arrangement is aided by the use of a bearing and hardened washers. Lifts according to the present invention can safely have a travel distance of up to 50 feet, and can manage payloads up to 1000 pounds.
