Abstract
Mining machines such as continuous miners and chain haulage units may include chain conveyors that are capable of deflecting laterally in order to travel through lateral turns. The chain conveyors may include flight members for pushing or urging material along a pan. The chain may be driven by one or more sprockets. In one independent aspect, a link for a chain conveyor includes a body including a first end a second end opposite the first end, a first opening proximate the first end and extending in a direction transverse to a direction of travel of the link, a second opening proximate the second end and extending in a direction transverse to the direction of travel of the link, and a relief opening extending through the link body and positioned between the first end and the second end.
