Abstract
A conveyor system for moving loads, comprises including an overhead rail (11, 211) along which run motor-driven carriages (10), each carriage having a motor-driven wheel (13, 113, 213, 313, 413, 513) resting on the upper part of the rail and a frame (12, 15) ending on the lower part of the rail with a device (16) for supporting a load. The wheel (13, 113, 213, 313, 413, 513) has a rolling surface (22, 122, 222, 330) which rolls over a corresponding rolling surface (25, 129, 225) on the rail and also a gripping surface (23, 123, 223, 330) which grips a corresponding gripping surface (24, 128, 224, 324, 424, 524) of the rail. One of the gripping surfaces (23, 123, 223, 330 or 24, 128, 224, 324, 424, 524) has rigid gripping teeth (23, 123, 224, 330, 430, 530), while the other of the gripping surfaces (24, 128, 224, 324, 424, 524 or 23, 123, 223, 330) is made of elastically pliable material in order to receive an imprint of the teeth.
