ABSTRACT:
The invention relates to a scaffold with vertical supports arranged spaced apart next to one another and/or behind one another, with horizontal carriers arranged between adjacent vertical supports and with scaffold decks which releasably lie at their end regions on oppositely disposed horizontal carriers another and preferably extending parallel to one another, preferably by means of hooks,. The invention consists of the fact that the scaffold decks have at least one laterally projecting guide stop close to at least one end which can be slidingly placed on a horizontal carrier extending perpendicular to the horizontal carriers carrying the end regions of the relevant plate and arranged at the same height such that the scaffold deck held by an operator at the end remote from the guide stop can be displaced by sliding the guide stop on the associated horizontal carrier to the opposite horizontal carrier and can be pushed by tilting—preferably taking place after lowering of the end—about the side carrying the guide stop, at its end region, in particular the hooks, over the opposite horizontal carrier and can be placed into the position of use onto the associated opposite horizontal carriers by tilting back and lowering into the horizontal position.
