Which of the following is one of the seven required safety devices under 29 CFR 1926 Subpart CC?

• A. Crane level indicator
• B. Boom stops
• C. Jib stops
• D. Brake locking feature

Answer: (A)

Having a crane level indicator is essential because it directly supports safe setup and operation by showing when the crane is level. In overhead and gantry crane operations, being level is crucial; a tilt can cause the load to swing, bind, or tip the crane, even if the rest of the system seems fine. The level indicator provides a clear, immediate signal to the operator to stop and correct the setup before lifting, helping prevent tipping and load instability.

Under 29 CFR 1926 Subpart CC, there are seven safety devices required on these cranes, and the crane level indicator is one of them. The other options—boom stops, jib stops, and brake locking features—are not listed as one of the seven required safety devices in this regulation. They may be present for other safety reasons or on specific crane configurations, but they are not the mandated device described in this question.
