Abstract
A pneumatic lifting device includes a base, a first mast attached to the base, and a second mast attached to the base opposite the first mast. The first mast has a first rail extending therealong, and the second mast has a second rail extending therealong. A lift platform is operatively coupled to the base. The platform includes a first pair and a second pair of bearings coupled thereto so as to move in conjunction with the lift platform. The first pair of bearings is operatively coupled to the first rail so as to enable the first pair of bearings to move with respect to the first rail. The second pair of bearings is operatively coupled to the second rail so as to enable the second pair of bearings to move with respect to the second rail.
