1. A conveyor system for handling a heavy object which must be transported along a path between spaced positions and which may necessarily be oriented angularly relative to said path on approach to or departure from at least one of said positions, comprising:

  • a platform on which the object is supported bodily for transportation along said path;

    a pair of spaced parallel tracks along said path between said positions under said platform;

    a respective member to run along each of said tracks;

    means for selectively driving said members along the respective tracks;

    means swivelly connecting one of said members to the underside of said platform;

    guide track means carried by the underside of said platform operatively aligned with said swivelly connecting means and extending transversely relative to said pair of tracks; and

    a runner block running along said track means and swivelly connected to the other of said members;

    whereby the platform can be moved along said parallel tracks by operating the driving means for both of said members in unison, and the platform can be swivelly moved by selectively operating the driving means for either of said members, the platform swiveling about said swivelly connecting means and said runner riding along said track means to compensate for changes in angularity of the track means relative to the tracks during the swivelling movements of the platform.
