    (57) An arrangement in transport vehicles in order to lock to each other for the duration of transport a fixed loadbearing frame (5) and an also loadbearing structural component (3) which is pivotable to the side for the duration of loading and unload­ing, and to support during the loading and unloading this structural component pivotable to the side. The arrangement comprises a support boom (8) which is articulated to the frame of the transport vehicle and can be placed under the said structural component pivotable to the side. When turned into a position parallel to the transport vehicle, the support boom (8) serves as a latch which locks the joint (6) between the loadbearing side wall (4) of the structural component (3) pivotable to the side and the frame of the freight wagon.
