Which statement about crane categories is true?

• A. The yellow truck crane is category 3
• B. The white truck crane is category 4
• C. The white truck crane is category 2
• D. The yellow truck crane is category 1

Answer: (B)

Crane categories define the class and capacity of a crane, which in turn dictates the safety procedures, setup requirements, and operator qualifications needed. In the material this question draws from, a category 4 designation is reserved for larger, more capable mobile cranes, such as a truck-mounted crane with higher lifting capacity and more complex setup considerations. The white truck crane fits this description, so it is categorized as category 4. The other statements would place the same crane in lower categories or assign a category that doesn’t align with how the manual maps crane types to categories, which is why they aren’t true.
