NCCCO Lattice Boom Practice Test 2025 – Complete Exam Prep

The cantilever of a lattice boom crane refers to the boom that extends beyond the support or pendant connections without any additional support underneath it. This definition is crucial for understanding how the boom operates when lifting loads, as the cantilevered section experiences different forces and moments compared to the supported sections. The effective length of the cantilever can significantly influence the crane's stability and load capacity, especially when it comes to calculating the crane's load chart and ensuring safe operations.

In lattice boom cranes, the design allows for a significant portion of the boom to extend out, which is critical during certain types of lifts. The boom's structural integrity and the distribution of weight play essential roles in ensuring that the crane operates safely when extending loads. Understanding the cantilever aspect is vital for operators in making informed decisions about lifting loads and adhering to safe practices.
