How does weather impact crane operations?

• A. Wind, rain, ice, and lightning can affect stability, visibility, and electrical hazards; operations should be paused if conditions are unsafe.
• B. Weather has no effect on crane operations.
• C. Only wind affects stability.
• D. Sunny weather is required for all lifts.

Answer: (A)

Weather affects crane operations by introducing safety risks in stability, visibility, and electrical hazards. Wind creates dynamic lateral loads on the crane and any lifted load, and gusts can push equipment beyond its rated capacity or cause sway that endangers personnel and nearby structures. Rain and ice change surface conditions, making decking and ground surfaces slick and reducing friction for movement, while ice adds extra weight and can bind mechanical components. Lightning presents a direct electrical hazard, especially when operating near power lines or using suspended electrical equipment. Reduced visibility from rain, fog, or snow can hide hazards and delay signal communication, and wet, unstable ground can compromise crane stability. Because of these factors, lifting should be paused or halted when conditions are unsafe. The other choices miss important weather effects or imply weather is never a factor or always suitable, which isn’t accurate.
