ABSTRACT:
Two mechanically identical cranes whose luffing jibs have the same maximum and minimum out-reach and which have their own slewing machinery, are mounted via respective supporting structures on a common foundation, at the same level for rotation about the same axis by bearings and an axle which provide a compact journalling of the supporting structures upon the foundation.
