Abstract
A longitudinally divisible crane boom segment includes at least a first and a second section that are easily nested together for transport. The sections each include at least one chord member, at least one bracket attached to the section, and a plurality of partial lacing elements. Each partial lacing element has a first end permanently attached to the at least one chord member and a second end. The second end of at least one of the plurality of partial lacing elements of the first section is connectable to a bracket attached to the second section to hold the sections in a nested fashion.
