Abstract
Abstract Automated installation for the laying for masonry on a wall, especially of a converter, comprising an operating station with a work plateform movable vertically inside the enclosure and capable of rotating about the vertical axis of the latter, areas for the simultaneous storage of two pallets of bricks on the platform, a robot for handling and laying the bricks, a monitoring and control station, retractable props for stabilizing the operating station and a device for raising and lowering pallets of bricks. The entire operating station is supported by a telescopic mast mounted on a turntable of a movable floor which is located outside the enclosure and with which the operating station forms a retractable self-propelled or towable unit.
