1. Labour-facilitating apparatus for the conveyance of building material from a higher position to a lower position or vice versa in the vicinity of the place at which the material is used, such as conveyance of shaped bricks for the construction of internal walls, in particular for the lining of converters, metallurgical furnaces, holding furnaces and suchlike, with a supporting structure consisting of a stand (7) for a continuous chain conveyor (10), which is able to be withdrawn partially away from the stand, in order to form, with its part which has been withdrawn away from the stand (7) over the curved part of a guide (21), a vertical conveyor section for the said conveyance from a higher position into a lower position or vice versa, characterized in that the continuous chain conveyor (10) is movable in a flexible channel (11) consisting of channel sections (11a, 11b, 11c) articulated to each other, which channel is supported by the stand (7) and together with the chain conveyor (10) is able to be withdrawn in relation to the stand (7) in order to form a protective channel along the vertical conveying section of the chain conveyor, which at least partially surrounds this vertical conveying section, in order to hold material on this part, and that the flexible channel has circularly curved guide flanges (20) on the sides facing each other toward the interior, which flanges support the chain conveyor (10) for transfer to the said vertical section. |
