A tower crane operator observes the anemometer displaying a sustained wind speed of 65 km/h (40 mph). The crane's operational wind speed limit, as per the manufacturer's chart and site-specific wind plan, is 60 km/h (37 mph). What is the most appropriate action the operator should take?

Question: A tower crane operator observes the anemometer displaying a sustained wind speed of 65 km/h (40 mph). The crane's operational wind speed limit, as per the manufacturer's chart and site-specific wind plan, is 60 km/h (37 mph). What is the most appropriate action the operator should take?

Answer options:

• Continue operations cautiously, as the difference is minor and temporary. ✅ Immediately cease lifting operations and secure the crane in accordance with the site wind plan.
• Reduce the load weight and hoist speed, then continue operations.
• Inform the signal person and wait for their instruction before proceeding.

Correct answer: Immediately cease lifting operations and secure the crane in accordance with the site wind plan.

Explanation: Exceeding the manufacturer's specified operational wind speed limit, or the more restrictive site-specific limit, requires immediate cessation of lifting operations and securing the crane to prevent overturning or damage. Continuing to operate under such conditions is a significant safety hazard.
