Which documented source provides information on the number of cantilevered sections of lattice boom that can be fitted before installing pendants?

The boom sequence diagram is the documented source that provides detailed information about the configuration and assembly of the lattice boom, including the number of cantilevered sections that can be safely fitted before the installation of pendants. This diagram is critical for understanding the structural integrity and load distribution as various sections of the boom are added.

Using this diagram, riggers can visualize the sequence of assembly, ensuring that they adhere to the required safety protocols while preventing excessive cantilevering that could lead to instability. It serves as a key reference during rigging operations, helping to maintain safety standards and proper lifting procedures.

Other sources, such as the safety manual or job safety analysis, focus more on safety practices and risk assessments rather than specific technical configurations of equipment. The project schedule primarily outlines timelines and does not provide the necessary technical detail on boom assembly or pendant installation. Therefore, the boom sequence diagram is the most relevant and accurate document for understanding how many cantilevered sections of lattice boom are permissible before pendants are installed.
