Abstract

A conveyor channel section or pan is composed of upper and lower components each having U-shaped rolled side walls with inwardly-directed flanges and floor plates. Additional side plates fixed to the exteriors of the side walls of the lower component project upwardly alongside the side walls of the upper component. Recesses in the side plates mate with fittings on the side walls of the upper component and upstanding nuts and bolts secure the fittings in the recesses. The end regions of the pan can be provided with inclined deep pockets formed within welded-in shaped joining pieces which receive toggle-like coupling pieces used to connact adjacent pans together.
