Abstract (en)
[origin: EP0373617A2] A shiftable scaffold movable in sections on a wall has support shoes (11), which can be attached to the wall (12) at certain intervals in the direction of forward movement, and has at least two bearing rails (13) arranged spaced apart and extending along the wall (12) between at least two support shoes (11) in each case, and having at least one shiftable bracket (14) arranged so as to be shiftable and securable in the direction of forward movement on at least two bearing rails (13) arranged adjacently, the bearing rails (13) and the shiftable bracket (14) being shifted upwards alternately. Assigned to each bearing rail (13) is a linear drive (15) which advances the shiftable bracket (14) in the region of the assigned bearing rail in such small steps (S) in comparison to the length (L) of one section that uneven shifts of adjacent linear drives (15) by one step (S) are still absorbed by the elasticity of the interacting construction elements, and that all the linear drives (15) are jointly driven and controlled by a common drive and control device (22) in such a way that a further operating step is only initiated when all the linear drives (15) have completed the preceding operating step. <IMAGE>
