Module 4: Cranes and Rigging

What is the purpose of a boom angle indicator on a crane?

• To indicate the load limits of the crane

• To measure the angle and weight of lifted objects

• To restrict the angle of the boom when it reaches its highest position

• To verify lift calculations and determine if the load is within the load rating of the crane

What is the recommended way to protect employees from the Crane's swing radius?

• Completely barricade the entire swing radius of the equipment

What should be done if access gates are present on a crane?

• Equip them with a restraining device to prevent accidents

• Install warning signs around the access gates
