ABSTRACT:
A modular pan assembly for a longwall mine face conveyor includes an elongated deck plate flanked by a pair of parallel, elongated side rails to define the conveyor system feed path. Beveled longitudinal edges of the deck plate mesh into corresponding channels along inside surfaces of the side rails. Apertures penetrate side rails from outside surfaces into the floor of respective channels. The assembly is secured by welds between the side rails and the deck plate within the apertures and along a lower side rail channel wall.
