Abstract
A single-chain conveyor comprises a chain which runs centrally on the bottom of a conveyor trough and which has pushers which are secured to the chain by over-chain brackets which are guided along the trough bottom. The underside of the chain brackets are provided with slide surfaces which are made of a plastic material to facilitate the gliding movement of the brackets over the bottom of the trough. Pusher arms are also advantageously provided with slide surfaces made of plastic which engage in angle-profiled guide surfaces of the side walls of the conveyor trough.
