Abstract:
A conveyor system comprising:a longitudinally elongated rail and a pendant-type trolley member for movement along the rail, the rail being generally tubular and having an upwardly convex upper surface extending to an uppermost crest, and an upwardly concave lower surface spaced a distance from said upper surface, the trolley member comprising a body and a pair of spaced apart arm members extending upwardly from said body for placement along each side of said rail, each arm member including a bearing member for engaging said upper surface on opposite sides of the said crest to movably support the trolley member on said rail, wherein the trolley member is supported on the rail for movement longitudinally along the rail with the body below the rail, each arm member extending upwardly to above the track on a respective side of the rail and each bearing member engaging the upper surface of the rail with the trolley member substantially encircling the rail but for an open gap separating the bearing members by a minimum distance greater than a maximum distance the lower surface is spaced from the upper surface, wherein with the trolley member orientated so that one bearing member is adjacent the upper surface and the other bearing member is adjacent the lower surface, the rail passes through the gap to remove the trolley member from the rail or apply the trolley member to the rail.
