Which device shall be provided for outdoor stored bridge cranes?

• A. Mechanical brake
• B. Wind indicators
• C. De-ice boots
• D. Cab insulation

Answer: (B)

Outdoor storage exposes cranes to wind, so knowing the wind conditions at the site is essential for safe operation. A wind indicator gives a simple, visible indication of wind speed right at the crane, allowing the operator to decide whether it’s safe to move or lift or to secure the crane if wind is too strong. This directly supports safe handling when the crane isn’t in use. The other devices don’t address wind-related safety: a mechanical brake is for stopping motion, not monitoring wind; de-ice boots are for icing (not typical crane concerns); cab insulation protects the operator’s comfort, not wind safety.
