ABSTRACT:
A mobile conveyor installation is composed of a carrier frame composed of channels joined end-to-end on which a scraper-chain conveyor is mounted. Drive stations are provided at the ends of the conveyor and the frame and one or both of these have driven tracks for moving the installation. The conveyor and carrier frame can adopt a curved profile. A guide beam composed of articulated plates which can be braced and locked or released serves to guide the carrier frame and the conveyor. The guide beam is connected with rams to the conveyor or the carrier frame to effect relative longitudinal movement therebetween. The guide beam is raisable and lowerable from contact with the floor either directly or via the carrier frame. The plates of the beam are coupled to a traction chain which can be tensioned or slackened with a hydraulic unit to cause the plates of guide beam to become rigid for guidance or released for movement.
