A conveyor system is composed of a trolley and an elongated inverted U-shaped or C-shaped track which is formed without any machining involving removal of material by simple deformation of a sheet-metal blank. The track has a horizontal or vertical web, two vertical or horizontal legs extending from the marginal portions of the web, and two horizontal or vertical ledges which constitute the inwardly bent end portions of the legs. One of the ledges has a V-shaped cross-sectional outline and the other ledge has an inturned carrier for a toothed rack in mesh with a pinion driven by a motor on the trolley. The trolley has a first pair of rollers whose conical peripheral surfaces engage the opposite sides of the V-shaped ledge, and a second pair of rollers whose cylindrical peripheral surfaces engage the opposite sides of the other ledge. One roller of each pair is adjustable to ensure that both rollers of each pair engage the corresponding ledge with negligible clearance. The V-shaped portion of the one ledge can receive a steel rod which reinforces the track and is engaged by one roller of the respective pair of rollers.
In a conveyor system, the combination of a straight, elongated track having a substantially U-shaped or C-shaped cross-sectional outline and consisting at least in part of sheet metal, said track including a substantially V-shaped portion extending lengthwise of said track and a second portion spaced apart from and parallel to said V-shaped portion, and each of said portions having a first side and a second side, said track further including reinforcing means extending in parallelism with said V-shaped portion, and said track also including a pair of spaced-apart legs and a web between said legs, one of said legs comprising a ledge extending toward the other of said legs and including said V-shaped portion;
In a conveyor system, the combination of a straight, elongated track having a substantially U-shaped or C-shaped cross-sectional outline and consisting at least in part of sheet metal, said track including a substantially V-shaped portion extending lengthwise of said track, and said track also including a web and spaced-apart first and second legs flanking said web, one of said legs comprising a ledge extending toward the other of said legs and including said V-shaped portion, and said track further comprising reinforcing means extending in parallelism with said V-shaped portion, said reinforcing means including first and second profiled portions forming part of said track and disposed between said web and the respective legs;
In a conveyor system, the combination of a straight, elongated track having a substantially U-shaped or C-shaped cross-sectional outline and consisting at least in part of sheet metal, said track including a substantially V-shaped portion extending lengthwise of said track, and siad track also including a pair of spaced-apart legs and a web between said legs, one of said legs comprising a ledge extending toward the other of said legs and including said V-shaped portion, and said track further comprising reinforcing means extending in parallelism with said V-shaped portion, said reinforcing means including an elongated stiffening member extending into said V-shaped portion;
