An apparatus for facilitating the conveyance of material and the erection of walls of closed circumference from bricks, such as refractory bricks, and particularly for lining converters, metallurgical furnaces, such as blast-furnaces, holding vessels etc. includes a vertical frame for supporting a working platform. The apparatus further includes a conveyer means comprising a vertical conveyance path for conveying material to the platform and a supply path for conveying material to the vertical conveyance path. The vertical conveyance path and the supply path are constituted by two runs of an endless conveyor. One of the runs is extendable by shortening of the other run and vice versa.
