Red Seal Mobile Crane Operator Practice Exam

Question: 1 / 400

What is the typical maximum allowable wind speed for crane operations?

10-15 km/h

20-30 km/h

In crane operations, ensuring safety during high winds is crucial for both the equipment and personnel on site. The typical maximum allowable wind speed for crane operations is generally in the range of 20-30 km/h. At this speed, cranes can generally maintain their stability and operational effectiveness, reducing the risk of tipping or losing control of the load being lifted.

Exceeding this wind speed can lead to dangerous conditions, as wind can exert significant lateral forces on the boom and load, destabilizing the crane and posing risks to operators and bystanders. Many manufacturers and safety guidelines specify this range because it balances operational efficiency and safety. Hence, knowing this threshold is vital for making informed decisions regarding when to halt operations or implement safety measures.
