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.
Cette invention concerne un tronçon de flèche de grue formé d'au moins une première et une seconde sections séparables longitudinalement et faciles à gerber pour le transport. Les sections comprennent chacune au moins un longeron, au moins un moyen d'attache et une pluralité d'éléments partiels de triangulation. Chacun des éléments partiels de triangulation ci-dessus est solidaire par un de ses bouts du longeron susmentionné. Le second bout des éléments partiels de triangulation du premier longeron se raccorde au moyen d'attache dont est équipée la seconde section. Cette opération a pour but maintenir les sections imbriquées les unes dans les autres.
