17 are designed such in their bend that a partial embracing or enclosing of a crosspiece 4 is possible fig1 shows an arrangement of the ladder platform of the invention in which it serves as a stepping platform the plate 1 points thereby upwardly while the edge 2 is arranged downwardly the suspension link 5 is attached to the upper crosspiece 4 in such a manner that it at least partially embraces said upper crosspiece from above furthermore the recess 23 of the edge 2 is form lockingly engaged with the lower crosspiece 4 the two mounting plates 8 of the mounting element are moved over the lower crosspiece 4 and embrace said lower crosspiece form lockingly such that the elastic element 16 causes an abutment of the first leg 11 of the locking projection 13 and of the base area 15 against the respective sides of the lower crosspiece 4 fig2 shows an arrangement of the inventive ladder platform in which same serves as a storage platform the plate 1 is arranged such for this purpose that the edge 2 projects upwardly the suspension link 5 embraces an upper crosspiece 4 of the ladder while the mounting plates 8 of the mounting element are in turn mounted on a lower crosspiece 4 the elastic element 16 also in this case causes an abutment of the first leg 11 of the locking projection 13 and of the base area 15 against the respective sides of the crosspiece 4 fig3 is a top view of the web 9 and of the two mounting.
