A question posed to the Crane and Hoist Professionals group on LinkedIn asked if “Lugs” were required on underhung cranes. Most group members responded, “Yes,” because the ASME B30.11 or MH 27-1 requires it. This is not surprising because the text of many standards make them sound like they set requirements and well intended readers believe it. Let’s get technically correct:
• In the U.S., OSHA enforces the Code of Federal Regulations, for Safety and Health, with fines for non-compliance.
• In order for something to be “required” for safety and health, OSHA has to require it.
• ASME, ANSI, NFPA, NEC and other voluntary standards are only required to be followed if OSHA incorporates it.
• OSHA currently has no regulation covering underhung cranes.
• 29 CFR 1910.179 covers only top running bridge and gantry cranes.
• ASME B30.2, which is incorporated in part, covers top running cranes.
• Cranes only have to meet requirements that existed at the time of manufacture, grandfathering.
• Grandfathering and technical correctness exists until an accident.
• After an accident, OSHA can use the B30.11 lug requirement via the “general duty clause”.
• Lawyers have no rules.
• Lugs are not required on new or existing underhung cranes and employers cannot be required to install them.
• Employers must maintain a safe and healthful working environment.
• Employers can be held liable for not complying with “voluntary” standards.

Cranes have always been used to get construction personnel into hard to reach places.
Before OSHA, a worker riding the crane’s hook was common, this is still true in some places today. Until the mid-1980’s, hoisting personnel with a crane was one of the main causes of crane-related deaths. With new regulations in place, there are fewer fatalities. Lifting personnel with a crane should be a last resort, after exhausting all other safer possibilities. In fact, in an effort to discourage hoisting personnel with a crane, OSHA has made the requirements time consuming and costly.
The currently approved methods of lifting personnel are hook suspended baskets, boom tip attached baskets, boatswain (bosun’s chairs), and marine transfer units (Billy Pughs).
May 27, 2014 (Sanford, Fla.)—Crane Institute of America announces the release of the first cards in the new Ready Reference Series. The laminated, pocket-sized cards cover topics that are useful for lift directors and crane and rigging inspectors, as well as others with responsibility for overseeing crane activities on the job site.
The first three cards in the Ready Reference Series feature Wire Rope Inspection, Crane Setup, and Working Around Power Lines.
“Both ASME B30.5 and OSHA 1926 Subpart CC for Cranes and Derricks in Construction discuss the job site responsibilities for controlling entities, site supervisors, lift directors, assembly/disassembly directors, crane owners, and others. The Ready Reference Cards are designed to provide these individuals with technical and safety guidelines that are reflection of industry standards and regulations,” said Jim Headley, President and CEO of Crane Institute of America.
The Wire Rope Inspection card makes it easy for inspectors to determine when the wire rope must be removed from service. The card lists wire rope sizes from 3/8” to 1-3/4” (10 mm to 45 mm on back) and the minimum diameter allowed in both fractions and decimals – taking the math out of the inspection.
Crane Setup addresses site preparation, one of the most important aspect of crane operation and explains who is responsible for ensuring the ground will support the crane and loads lifted. Additional information is provided on positioning the crane, maintaining clearances with power lines, and avoiding potentially unstable ground.
Working Around Power Lines summarizes key information about the clearances required when working near or driving under power lines, how and when to use signalpersons. It also includes reminders about how operators and other personnel are to respond in case of contact with live lines.
Future Ready Reference cards will cover Assembly/Disassembly and other topics for individuals...
