Whose guidance should be consulted for wind-related operating conditions?

• A. Crane manufacturers
• B. Weather service
• C. Local regulations
• D. Company policy

Answer: (A)

Wind-related operating limits come from the crane’s own design and the exact specifications provided by the manufacturer. The manual for each crane model includes the maximum wind speed at which lifting is considered safe, along with how factors like load, boom angle, radius, and outriggers affect stability. Because these limits are specific to the crane’s configuration, the manufacturer is the most reliable source for determining safe operating conditions in wind.

While weather service information is essential for planning and detecting hazardous conditions, it does not define the crane’s allowable wind limits. Local regulations and company policy may enforce procedures or thresholds, but they must align with the manufacturer’s ratings. So, consulting the crane manufacturer ensures you have the correct, model-specific wind limits for safe operation.
