An overhead track assembly for an amusement-park ride has a plurality of bases adapted to rest on the ground and each supporting an upright post having an upper end forming a support surface and having a pin projecting upwardly from this support surface. A plurality of track sections each include a central hollow beam having one end formed with an upper eye and another end formed with a lower eye, a pair of generally parallel rails flanking the beam and adapted to guide a car longitudinally along the beam, and transverse members interconnecting these rails and the beam rigidly. The track sections are secured to the upper ends of the posts with the pins at these upper ends extending upwardly through the lower eye of one respective beam and through the upper eye of another respective beam. Flat fence panels engage between the posts and bases to hold these posts and bases in place during assembly of the track, and each of the track sections is provided with a zig-zag chain having a ring located directly above the center of gravity of the respective section for easy assembly of the track with a crane. |
