ABSTRACT:
The present invention relates to a crane boom for transport as container freight which can be assembled from a plurality of boom parts which each have coupling pieces at the front face end for the putting together of the boom parts, wherein the boom parts each have at least one bottom chord and can be placed next to one another such that the bottom chords of the boom parts together form a continuous runway free of offset and faults for a crab. The invention further relates to a transport apparatus for the transport of boom parts of a crane boom of this type as container freight. In accordance with the invention, the boom parts of the crane boom, despite the identical bottom chord track dimensions which provide a runway for a normal crab on the bottom chords largely free of offset and faults, have different cross-sections such that the boom parts can be pushed into one another for the purpose of transport, whereby the space in the boom parts is also utilized.
