A conveyor system includes an elongate track or rail and a number of trolleys used to store and/or convey various items along the track or rail. In cross-section, the rail is generally crescent shaped with a hollow interior, having an upwardly convex upper surface and an upwardly concave lower surface. The trolleys consist of an elongated trolley bar or support suspended on one or more trolley pendants which movably engage and travel along the rail. The trolley pendants are generally U-shaped having a central bight or body to which the trolley bar is coupled, and two spaced apart arms which project from the bight. The arms of the trolley pendant are spaced from each other by a distance selected greater than the lateral width of the rail. The arms of the trolley pendant define a throat portion between the arms. A bearing member is spaced towards the end of each arm, projecting inwardly towards each other part way into the throat. The bearing members are spaced from each other by a minimum distance which is selected less than the lateral extent of the rail, but greater than the maximum spacing in between the upper and lower rail surfaces.
