What is the maximum permitted wind speed when climbing a tower crane?

The maximum permitted wind speed when climbing a tower crane is 20 mph. This limit is established to ensure the safety and stability of the crane during the climbing process, which involves the crane being elevated to a higher position. Excessive wind can affect the crane's ability to maintain its balance and could lead to operational hazards, including the risk of tipping or uncontrollable movements.

Climbing operations require that the crane is stable and securely anchored. The 20 mph limit is set based on operational safety guidelines and regulations, and staying within this threshold helps prevent accidents, ensuring that cranes can be safely climbed without compromising their structural integrity. When wind speeds exceed this limit, it is prudent to halt climbing operations until conditions improve.
