Abstract
A mining installation has a scraper-chain conveyor for transferring material and which is constructed in known manner from a series of channel sections joined end-to-end. A shifting apparatus serves to bodily displace the conveyor in a longitudinal direction and the connveyor is reinforced by means of L-shaped stiffening members attached to the exteriors of the side walls of the channel sections. These stiffening members or plates are interconnected by means of coupling plates which permit pivotal movement in a vertical plane as well as some free horizontal movement. The upper sides of the stiffening plates extend over the side walls of the channel sections and are provided or formed with webs or the like for the reception and connection of further barrier plates and their supports for example.
