Lacing for American Crane CC3113 MOD. 9260

The lacing tube, identified by part number 815988-2, serves as a structural member within the lattice boom assembly of the crane. It functions as a cross-bracing component that provides necessary rigidity and support to the boom structure, helping to distribute mechanical loads and stresses across the framework during lifting operations. By maintaining the geometry of the lattice, this component ensures the overall stability and structural integrity of the boom system.

This component is manufactured by American Crane and is specifically engineered for the American Crane CC3113 MOD. 9260 crane model. The part measures 92 inches in length, with an outside diameter of 2 1/4 inches and a wall thickness of 0.095 inches. These precise dimensions are required for proper fitment and alignment within the existing boom lattice structure.

In lattice boom cranes, lacing members act as the diagonal or horizontal struts that connect the main chords of the boom. These tubes are welded into the assembly to prevent buckling and to manage the compressive and tensile forces generated during heavy lifting tasks. Maintaining the correct dimensions and material properties of these members is necessary to support the rated load capacity of the crane boom.
