During the assembly of long lattice booms, what is the maximum limitation on each group raised?

When assembling long lattice booms, the limitation on each group raised being related to the maximum cantilever length is significant because it ensures safety and stability during the lifting process. The maximum cantilever length is defined as the farthest distance that a load can be safely extended beyond its support. Exceeding this limit could lead to an unstable configuration, increasing the risk of tipping or structural failure. This guideline is crucial in crane operations and rigging practices, as adhering to the maximum cantilever length prevents accidents and promotes safe working conditions.

The other options, while they may contain elements of safety, do not directly address the specific limitations of cantilevering a boom assembly. The maximum lift height and assembling in pairs are important considerations in the overall lifting process, but they do not specifically define the structural limitations of the boom’s cantilevered condition. Similarly, stating that there is no limitation disregards safety protocols and engineering principles that are in place to protect workers and equipment during such operations.
