ABSTRACT:
The arrangement is especially intended for mining equipment for driving a winning machine 20 along a face conveyor 11, on which the machine rides. The conveyor sections carry corresponding rack sections 30 having formations 40 each comprising two laterally spaced teeth 40a,40b, defining a channel 41 therebetween. The pinion has a disc-shaped body 43 having apertures 45 loosely mounting bands 44 of the type provided in a round-link chain. The bands engage with the teeth and the loose-mounting allows slight vertical and horizontal articulation of the bands. This reduces wear, especially at the joints between rack sections.
