Load bearing material handling system having pneumatic and electrical delivery capabilities

摘要

A load bearing material handling system including a rail having a hanger portion, a body portion defining a conduit extending for at least a portion of the length of the rail and a flange portion adapted to movably support a trolley thereupon. A splice connector may be disposed between adjacent, sequential ones of a plurality of rail segments which are coupled together to define the rail. The rail supports a pneumatic trolley having a pair of opposed frame members and a housing extending therebetween and which is adapted to supply air to a pneumatically actuated tool which is movably supported by the trolley along the rail. The rail may also support a load bearing trolley. Both the pneumatic and load bearing trolleys include opposed frame members having at least one trolley wheel adapted for rolling contact with a runway surface on the rail and at least one safety lug which projects over the plane of the runway surface of the rail so as to prevent the trolley from being inadvertently removed from the rail.
