Abstract
Improvements in the construction of rotating tower cranes to facilitate their assembly, essentially characterized by the fact that the single jib fixing cable is replaced by a second mounting cable associated with a set of rigging coupled by a set of pulleys and linked to a maneuvering winch that causes, depending on the case, a tension or a relaxation of said second mounting cable, so that the tower being made up of two sections articulated one to the other, with the lower element articulated on the rotating platform of the With the crane and the articulated upper element at the corresponding end of the boom, a locking member is provided for said articulation.
