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. The summation of the clearances between projections and recesses in the set of successive link components is at least equal to the total movement obtainable between any pair of conveyor pans.
