<p>A load bearing material handling system including a rail (44, 46, 48) having a hanger portion (70), a body portion (74) defining a conduit (98) extending for at least a portion of the length of the rail and a flange portion (72) adapted to movably support a trolley (200, 400) thereupon. The flange portion includes at least one runway surface (86) and at least one kick up surface (90) disposed in spaced relationship with respect to the runway surface so as to define a mounting surface (87) disposed therebetween and which is adapted to support an electrical bus (304) along at least a portion of the length of the rail. The rail supports a pneumatic trolley (200, 400) having a pair of opposed frame members (202) and a housing (204) extending therebetween and which is adapted to supply air to a pneumatically actuated tool (236) which is movably supported by the trolley along the rail. The rail may also support a load bearing trolley (600) as shown in the Figure.</p> |
