What are the two main standards that cover mobile cranes?

• A. OSHA 1926.1400 and ASME B30.5
• B. OSHA 1910.180 and ASME B30.1
• C. ASME B30.5 and ISO 4305
• D. OSHA 1926.1400 and API RP 2A

Answer: (A)

Focusing on mobile crane safety, the most important pair of standards combines a regulatory framework with a specific safety guide for the equipment. In the U.S., that means OSHA’s construction standard for cranes and derricks (29 CFR 1926.1400 series) alongside the ASME Safety Standard for Mobile Cranes (ASME B30.5). The OSHA provision sets the legal requirements for on-site responsibilities, training, inspections, and safe practices during construction work. The ASME B30.5 standard provides the detailed safety criteria for how mobile cranes should be designed, operated, set up, inspected, and maintained in daily use. Together, they define what must be done and how it should be done to keep operations safe.

Other options don’t serve as the two primary standards for mobile cranes in this context. For example, general industry crane rules under OSHA 1910.180 cover overhead/gantry cranes rather than mobile cranes in construction, and ASME B30.1 addresses different crane types. ISO 4305 is an international standard, and API RP 2A relates to offshore oil and gas operations, not the core mobile crane safety framework used in most construction settings.
