Question: A crane operator is setting up a mobile crane to lift a 2,500 kg load. The crane's load chart indicates a maximum capacity of 3,000 kg at the planned radius and boom angle for this specific lift. Which of the following is the most important factor for the operator to consider before proceeding with the lift according to CSA Z150?

Answer options: ✅ The ground conditions and stability under the outriggers.

• The colour of the load's rigging slings.
• The crane's annual inspection date.
• The operator's personal protective equipment (PPE) for the day.

Correct answer: The ground conditions and stability under the outriggers.

Explanation: According to CSA Z150, ensuring proper ground conditions and stability for the outriggers is paramount to prevent crane overturning, even if the load is within the crane's rated capacity. While other factors like annual inspection and PPE are important, stability is directly related to the safety of the lift itself.
