Abstract: A flexible track (10) is held captive in an armoured face conveyor and comprises a plurality of blocks (14) arranged in longitudinally spaced relation with a pair of links (15) at opposed transverse sides of each adjacent two blocks interconnecting said blocks and forming apertures (18) between adjacent blocks. The blocks (14) have side projections (16) and the links (15) have corresponding apertures which are of slightly greater dimensions longitudinally to permit a small amount of longitudinal movement (end-float) of each block (14) relative to its two pairs of links (15). Each block has a vertical aperture (22) through its body, the apertures (22, 18) in the blocks and between the end faces (20, 21) of adjacent blocks being adapted to receive a tooth (25) of a toothed wheel (26) mounted on a machine movable along the conveyor.

Abstract: A pinless haulage drive chain formed of a series of rack-form link components each having complementary shaped parts at opposite ends, one end of which has a projection of T-shaped in plan view and the other end having a recess of T-shape in plan view to receive as a clearance fit the projection of an adjoining link component. Each link component also has a central spine of upstanding rack formation and integral therewith on either side thereof two walls forming a saddle having a wall of lesser depth to be used as a trapping means for a mineral mining machine on its traverse along a conveyor, and a deeper wall to be encompassed by trapping means for the link itself via a shoulder extending from this wall. The chain may be used in a scraper chain conveyor comprising conveyor line pans having a range of movement therebetween.
