ABSTRACT:
According to the invention, the maintenance scaffold (10) is assembled as follows: in a first step, an illuminated ceiling, which lies below the collapsed maintenance scaffold (10), is taken down. Suspension members (17) are then brought into a vertical position. The platform (12) and flap (13) are lowered vertically until they reach the bearings (19) of the suspension members (17). Before mounting the platform (12), the maintenance personnel must unfold the ladder (18) and open the flap (13) upwards. Once the personnel has mounted the platform (12), the flap is closed (13) by means of a handle, in such a way that the entire platform can be used as a working scaffold. With the maintenance scaffold (10) in the working position, the height for a regulatory passage (U) is maintained, as determined by the distance between the cabin ceiling (14) and the platform (12).
