What section of the crane is required to be barricaded?

• A. Swing radius of the outer most body
• B. The operator cab
• C. The boom tip
• D. The counterweight area

Answer: (A)

Barricading the area around where the crane can rotate and move its load is essential. The swing radius defines the space the crane’s outer parts and any attached load can reach as the boom turns. If someone enters that area while the crane is lifting or rotating, they can be struck by the load or by moving components, which is a major safety risk. Keeping that zone blocked off creates a clear exclusion area so workers aren’t exposed to unpredictable motion. The operator cab is the control space and is kept accessible to the operator during operation, not barricaded as a general rule. The boom tip moves within the swing radius, so it’s already covered by barricading the broader zone. The counterweight area is hazardous, but standard practice emphasizes guarding the crane’s rotating reach to prevent entry during operation.
