Usually the flatbed must be raised according to the required subframe height. Since the standard flatbed version affected here is provided with very high, u-shaped cross-members, it is possible to perform the following procedure:

The cross-members of the standard flatbed are cut out in the areas the chassis side-rails in such a way, that it is possible to fit in precisely the continuous subframes and to connect them to the cross-members by means of welding. (Position of subframes exactly above the standard side rails, see illustration below.) Dimensions of subframes and attachment of the loading tailboard to be performed according to our construction guideline.

The attachment of the standard flatbed, which is modified as described, can be performed without changing the chassis, however, appropriately longer screws are to be used. The spacing between flatbed cross-member and chassis brackets is to be levelled out with shims (bushings).
