establishment of the rationalization of the transfer of materials of materials for for

摘要

The device serves for rationalising the laying of bricks for erecting a masonry structure. It consists of a platform (1) which is able to move with the aid of wheels (2) and has a vertical supporting column (3) rotatable about its longitudinal axis. A plurality of jibs (6) angularly offset with respect to one another are arranged on said supporting column and a hoisting rope (9) runs over each jib (6). Each hoisting rope (9) is assigned a rope drum (10) and a drive motor (11). Four jibs (6), each offset by 90 DEG with respect to one another, are advantageously provided on the supporting column (3), and the hoisting ropes (9) carry grippers (13). Separate motors are provided for driving the wheels (2) and for rotating the supporting column (3). Furthermore, a vertically adjustable working platform (16) is arranged on the platform (1) and/or on the supporting column (3). The length and width of the working platform (16) are so dimensioned that they lie within the enveloping circle of the ends of the hoisting ropes (9) hanging from the jibs (6). IMAGE
