Lacing tube for Terex HC275

The lacing tube serves as a structural member within the outer boom section of the Terex HC275 crane. It functions as a diagonal or transverse connector between the main chords of the boom, establishing the reticular framework necessary for the crane boom assembly. This component is integrated into the welded structure of the 40-foot 92HI boom section, which is compatible with AC 4408 and earlier model configurations.

Lacing tubes are positioned to provide torsional and flexural rigidity to the boom structure. By connecting the main chords, these tubes distribute operational loads across the boom framework, which helps maintain the intended shape and structural integrity of the boom under various lifting conditions. Proper alignment and installation of these components are necessary to support the load-bearing capacity of the crane boom.
