Question: A site's Weather Limits policy for crane operations specifies a maximum sustained wind speed of 48 km/h. If the forecast indicates sustained winds of 40 km/h with gusts up to 55 km/h, what is the appropriate action?
Answer options: ✅ Suspend the lift until wind speeds are consistently below 48 km/h, including gusts.
- Proceed with caution, as sustained winds are below the limit.
- Monitor the wind speed actively and proceed if gusts are infrequent.
- Temporarily reduce the load capacity rating by 10% and proceed.
Correct answer: Suspend the lift until wind speeds are consistently below 48 km/h, including gusts.
Explanation: Crane operations must typically cease when sustained winds or gusts exceed the manufacturer's or site's specified limits, as gusts pose a significant risk to load stability and crane control. Safety always prioritizes the higher wind reading.
