Abstract
An L-shaped device constituting a side or barrier plate for attachment to the side wall of the channel section or pan of a longwall scraper-chain conveyor has connectors at the end regions of a main plate-like body beneath a welded-on upper flange. The connectors have an interengageable projection and recess and possess bores extending parallel to the main plate for receiving fixing bolts. A row of non-circular shaped apertures is provided in the main body and is aligned with the connectors. The row of apertures receive bolts used to secure the device to the channel section or pan. A pair of upstanding webs is fixed to the main body beneath the flange and serve to receive a mounting pin for mounting a guide or shifting ram for example.
