Abstract
A track assembly comprises an inner channel member and an outer channel member, the outer channel member having opposing flanges with a conduit for receiving an air line for operating the assembly. An inflatable air bag is between the inner and outer channel members for raising and lowering the air bag. Rollers attached to the inner channel member are raised and lowered as the air bag raises and lowers the inner channel member. The air line, which is flexible and compressible, for operating the air bag, is releasably attached externally the channel members in and protected by the conduit by opposing spaced ribs. The air line is squeezed between the ribs during insertion into the conduit.
