In many cases when wind speed exceeds ______ mph it is advisable to stop operations

• A. 20 mph
• B. 25 mph
• C. 30 mph
• D. 35 mph

Answer: (C)

Wind safety in crane operations centers on how wind adds unpredictable, external forces to the crane and any suspended load. As wind strengthens, gusts can suddenly push the boom, jib, or load off balance, causing violent sway or drift. Those rapid movements increase the risk of losing control of the load, tipping the crane, or damaging outriggers and the supporting surface, especially if ground conditions are not firm. Because the danger rises quickly with stronger winds, many sites adopt a stop-point: when wind reaches that level, continuing work isn’t safe and operations are paused to protect people and equipment. The exact limit is defined by the crane’s design, weight and configuration, ground conditions, and the site’s safety plan or manufacturer guidance, so workers rely on those rules to determine when to halt activity. Wind readings should be taken at the job site and monitored by a competent person to decide whether to continue or stop.
