all inspection criteria on the tag. Tags generally include the phrase, “Follow ASME B30.9 standards for proper use and inspection of the sling.” And that phrase is used for all types of slings because B30.9 is all-inclusive so far. But there is a need for some sort of regulatory standard anyone can get and have on the shelf.

Wire rope (Sections 1926.1413 and 1926.1414)

Mike Parnell is the president of Industrial Training International, Inc., Woodland, Wash. ITI provides crane and rigging training/consulting for U.S. and global clients. He is the ASME B30 Main Committee Vice-Chair, a member of fi ve B30 Subcommittees, CIC Rigging Certification Committee Chair, and is a charter member of the Association of Crane & Rigging Professionals.

Where wire rope is concerned, the new OSHA regulation includes a substantial enhancement. The old location was 1926.550(a)(7) , and it was fairly limited. There are now three categories, and the new designation points are 1926.1413 and 1414.

Category I deals with physical abuse related to wire rope, such as crushing, kinks, corrosion, and other things that can detrimentally affect the rope. It calls out for each shift to have a visual inspection but they don’t have to boom down to do that. Then it requires a monthly and an annual inspection, both of which are documented. The new regulation is more helpful and specific than the old requirements.

Category II has to do with broken wires and reduction of rope diameter of six-stranded, rotation-resistant, and pendant lines. A big difference in the regulation is the rule on the reduction of rope diameter of more than 5 percent from nominal diameter. An adjustment will be made across the B30 volumes with this rule. Previously, the regulation provided imperial measurements. Now, 5 percent is deemed sensible because it allows for a comparison regardless of whether the rope is imperial or metric. Almost all tower cranes use metric rope, so no imperial values would correspond to the published reference size.

Category III is for special issues related to core failure, power-line contact, or a broken strand. It’s a catch-all, and if these issues exist, you stop the use of the rope and see if it can be salvaged.

Another major change in the wire rope sections state that if these deficiencies are identified or located, it is possible to cut the rope to remove that bad section. You can’t rejoin the rope by splicing it. The whip line may get banged around and the rope chafed or some wires cut on the outside 10 feet from the headache ball. You can cut back 20 feet and reconnect the headache ball if you still have enough rope length to run the crane. A qualified person should determine if that rope is suitable to operate the crane. You should document how much rope was removed from the end, so new inspectors and the operator realize what is left for the rope length. This was done in practice, but nothing in print ever allowed it to be done before.

Other items point the inspector in the right direction, such as change of layer points or reverse bends where the rope bends 180° one way and 180° another way through the sheave system. The regulation also includes a whole new section on rope selection and installation criteria. Some of the items were already implemented in B30.5 documents, based on what application the rope is going
