Question: A crane is configured with a 35-metre boom. The load chart provides capacities at 10-metre and 12-metre radii. What impact does extending the boom to 40 metres, while maintaining the same radius, typically have on the crane's lifting capacity?
Answer options: ✅ The lifting capacity will decrease.
- The lifting capacity will increase.
- The lifting capacity will remain the same.
- The lifting capacity will only change if the counterweight is adjusted.
Correct answer: The lifting capacity will decrease.
Explanation: Generally, for a given radius, increasing the boom length decreases the crane's lifting capacity, especially due to structural limitations and increased leverage on the crane structure. More boom means less capacity at the same radius. The load chart would have separate entries or columns for the 35m and 40m boom lengths, showing reduced capacities for the longer boom.
