What is the correct NCCCO-style exam answer for a question about stability vs structural capacity?
Structural capacity is the crane's maximum lifting ability, while stability determines if the crane will tip over during operation.
On NCCCO exams, questions about stability versus structural capacity test your understanding of two critical crane limitations. Structural capacity refers to the maximum weight a crane can lift based on its boom length and configuration, as shown in the load chart. This is determined by the strength of steel components like the boom, cables, and hook block.
Remember: "STRUCTURE lifts, STABILITY tips" - Structure = max weight, Stability = tipping point
