The crane associated with the white truck belongs to which category?

• A. Category 2
• B. Category 4
• C. Category 3
• D. Category 1

Answer: (B)

Think about how the crane is mounted and used. The category used in this practice is tied to the crane’s installation and how it operates on site, which changes the rules for lifting and safety. A crane that’s built into a truck—a mobile unit that travels on roads and is set up with outriggers when lifting—belongs to the category that covers truck-mounted mobile cranes. The white truck with the crane shown is exactly that kind of setup: a crane integrated with a vehicle chassis, not a standalone or stationary crane. That alignment with a truck-mounted configuration makes the category for truck-mounted mobile cranes the best fit. The other categories describe different crane configurations that don’t match this image, so they wouldn’t apply here.
