The invention concerns a device in scaffolds comprising a row of brackets (1) which are fixedly mounted in spaced-apart relationship. The brackets (1) consist of a vertical stanchion (2) and of an outrigger arm (5) projecting from said stanchion beyond a side wall (4). Each outrigger arm (5) supports a wheel unit (6) depending from the lower face of the outrigger arm (5). A profile rail (7) is suspended from said wheel units (6), said rail gripping the wheel units and resting on the upper face of the pair of wheels of said unit. The profile rail (7) has a lower rail section (11) arranged to support travelling crabs (14). From the latter is suspended a working gondola (15) which is movable along the side of the wall (4) by means of said crabs (14). |
