ABSTRACT:
Described in a suspension conveyor system suitable for the use of conveyance units having two travelling rollers interconnected by an open yoke. The suspension conveyor system is universally applicable and capable of optimum adaptation to operating and space conditions in a given plant. To this purpose the system comprises changeover means selectively operable to tilt a conveyance unit to a left or right laterally suspended position or a center-suspended position to thereby permit for instance the radii of curved rail sections to be considerably shortened and particularly achieve a less complicated construction of required switches. In a preferred embodiment the switch is formed as an integral shaped member, so that the continuity of the rail circuit has not to be interrupted for guiding a conveyance unit onto selected branch rails.
