Abstract: Apparataus for butt joining hanging conveyor supports having a C-shaped rail section in which conveying hangers can travel back and forth along the rail section. The supports each have a hollow section above the rail section and trolley wires running along at least one vertical side of the supports. Connecting parts are disposed between ends of adjacent supports, the hollow section having at least one profiled section in the shape of a square standing on a point. A square tube connects the ends and bridges the connecting parts and are inserted into the profiled sections at the ends of adjacent supports. Tie rods connect the ends of the adjacent supoorts. At least one L-shaped angle iron is disposed on each of the top sides of the ends of adjacent supports. The angle irons are connected to one another via at least one screw bolt and act, on both vertical sides of the ends of adjacent supports, on the tie rods which connect the ends together.

Abstract: A rail for a track for a wheeled vehicle is generally elongated and has a substantially "I" transverse cross section providing an upper rail head and a lower rail foot joined by a web. The rail head is provided with at least one and preferably two laterally spaced apart longitudinally extending apertures, which are adapted to receive alignment pins so that when the rails are coupled to each other substantially end on end, the pins extend between abutting ends of the rails to maintain the rails in an abutting and substantially aligned relationship. A track is also provided including spaced apart rails with a plurality of spacers extending between the spaced apart rails to maintain the rails in a predetermined spaced apart relationship. The spacers can be pivotally mounted on the rails, so that the rails are able to move and pivot relative to each other such as for the adjustment of gauge, packaging, and transport.
