What is the maximum wind speed at which a tower crane should not be operated?

The maximum wind speed at which a tower crane should not be operated is often advised to be around 20 mph (9 m/s). Operating a crane in high winds can lead to dangerous conditions, affecting both the stability of the crane and the safety of the site personnel. Wind can cause the crane to sway or even lose its load, posing risks not only to the operators but also to those working nearby.

Many safety standards and manufacturer guidelines suggest that operations should cease at this wind speed to maintain safe working conditions. Therefore, recognizing 20 mph as the threshold reflects adherence to safety protocols which prioritize employee and public safety. Understanding these limits is crucial for tower crane operators, as they have to make decisions that ensure the integrity of the machinery and safety of the site.
