Abstract

A scraper-chain conveyor has channel-sections or pans arranged end-to-end along which a scraper-chain assembly is circulated. Each pan is composed of rolled side walls with a floor plate welded therebetween. The side walls are reinforced by upper and lower elongate bars welded to their exteriors. These bars have shaped apertures designed to accept and locate the heads and shanks of bolts used to fix attachments to the side walls. The side walls are recessed behind the apertures and these recesses define with the apertures, pockets for receiving the heads of the bolts.
