Crane Wind Weather Guide: Gusts, Loads, Thunderstorms, and Stop-Work Decisions
A weather guide for crane wind risk, including gusts, suspended loads, thunderstorms, and why stop-work thresholds matter.
Quick answer: Crane wind risk rises when gusts push on the boom, load, rigging, or surrounding structures, especially during thunderstorms.
Gusts vs average wind
A steady breeze may be manageable while sudden gusts can create dangerous load movement.
Forecasts should be checked for gust speeds, not just sustained wind.
Thunderstorm outflow
Storms can send strong outflow winds ahead of rain.
A site can go from workable to unsafe within minutes if a gust front arrives.
Planning
Crews need clear stop-work thresholds, secure communication, and time to lower or secure equipment before storms reach the site.
Local rules and manufacturer guidance should always control operations.
