An overhead trolley conveyor system comprising an overhead track and a plurality of trolleys, adjacent trolleys being connected by a flexible, inextensible member, said track comprising a pair of longitudinally extending, parallel angle irons and a plurality of longitudinally spaced strap members each of said angle irons having an inwardly extending flange and an upwardly extending wall, each of said strap members having a channel-shaped cross section with a pair of downwardly extending legs, each of said legs having a laterally inwardly facing surface canted from the vertical such that the lower portion thereof lies laterally outwardly from the upper portion thereof, said surface of one of said legs being fixedly attached to a portion of the laterally outer side of one of said walls, and said surface of the other of said legs being attached to a portion of the laterally outer side of the other of said walls, and each of said trolleys comprising a pair of tapered wheels interconnected by an axle and having a hanger attached thereto, each of said wheels being adapted to roll longitudinally along the upper surface of one said flange, each of said pair of angle irons being spaced a distance from the other sufficient to allow free extension of said hanger therebetween but insufficient to allow one of said pair of tapered wheels to extend therebetween before the other of said pair of tapered wheels contacts the inwardly facing surface of one of said vertically extending walls of one of said angle irons.
