Abstract

A channel section for a scraper-chain conveyor is reinforced on one or both of its side walls by means of an assembly which may be a one-piece component with elongate members mounted one above another and secured to the associated side wall to lie flush with the upper and lower surfaces of the latter. The members are connected by means of transverse brackets provided with slotted recesses which are shaped to receive the heads of bolts and the members themselves are also provided with recesses for receiving the heads of bolts or attachments. The bolts can secure attachments such as plates or guides to the channel section. Connectors which enable the channel section to be connected to other channel sections are provided at the ends thereof. These connectors and the brackets engage within a V-shaped longitudinal groove at the outside of the side wall.
