|New Crane Hook Task Group to Meet in November; Participation Requested
Standards to address crane hooks will be the focus of a new task group slated to meet during the November meeting of ASTM Committee A01 on Steel, Stainless Steel and Related Alloys. In response to a request for documents that specifically focus on the materials, manufacture and testing of these forged materials, Subcommittee A01.06 on Steel Forgings and Billets will work toward two documents, one for general use and one for severe service application.
Cranes lift various items from ladles of molten steel to structural steel beams at building sites, notes Ed Nisbett, A01.06 chairman, and the loads typically are suspended by a hook. Nisbett adds that severe duty refers to hooks that are more likely to be subjected to frequent use for loads close to the rated maximum.
The activity results from a manufacturers request for a document more focused on crane hooks than the currently used standard that addresses steel forgings for general industrial use. The new documents would be more directed towards such situations as those involving low operating temperatures that could occur on docksides and northern climates or in situations such as some building sites where the exact loads might not be known.
Nisbett comments that state and federal agencies such as American Association of State Highway Transportation Officials, the Occupational Safety and Health Administration, and the U.S. Army Corps of Engineers would be particularly interested in these proposed standards. The results of such focused documents would be a benchmark for the manufacture of crane hooks.
