Abstract

A scraper-chain conveyor channel section comprises a pair of side walls and a floor plate extending between the side walls and connecting the side walls together. Each of the side walls has upper, lower and intermediate inwardly-extending flanges. The floor plate is connected to the intermediate flanges of the two side walls. Each of the side walls is constituted by an upper profiled bar and a lower profiled bar, each of the profiled bars being a generally U-shaped rolled section. Each of the lower profiled bars has a bottom flange and a top flange parallel to the bottom flange. The top flange of each lower profiled bar forms a support surface for the associated upper profiled bar, and constitutes part of the intermediate flange of the associated side wall. Each of the side walls is provided with a connecting bar for laterally supporting the associated upper profiled bar. Each of the connecting bars is secured to the exterior of the associated lower profiled bar, and projects upwardly beyond the top flange of that lower profiled bar.
