18、, Safety Standard for Cableways, Cranes, Derricks, Hoists,Hooks, Jacks, and Slings, has been developed under the procedures accredited by the AmericanNational Standards Institute (formerly the United States of America Standards Institute). ThisStandard had its beginning in December 1916 when an eigh
19、t-page Code of Safety Standards forCranes, prepared by an ASME Committee on the Protection of Industrial Workers, was presentedto the annual meeting of the ASME.Meetings and discussions regarding safety on cranes, derricks, and hoists were held from 1920to 1925, involving the ASME Safety Code Correl
20、ating Committee, the Association of Iron andSteel Electrical Engineers, the American Museum of Safety, the American Engineering StandardsCommittee (later changed to American Standards Association and subsequently to the USAStandards Institute), Department of Labor State of New Jersey, Department of
21、Labor andIndustry State of Pennsylvania, and the Locomotive Crane Manufacturers Association. OnJune 11, 1925, the American Engineering Standards Committee approved the ASME Safety CodeCorrelating Committees recommendation and authorized the project with the U.S. Departmentof the Navy, Bureau of Yard
22、s and Docks, and ASME as sponsors.In March 1926, invitations were issued to 50 organizations to appoint representatives to aSectional Committee. The call for organization of this Sectional Committee was sent out October2, 1926, and the committee organized November 4, 1926, with 57 members representi
23、ng 29 nationalorganizations. The Safety Code for Cranes, Derricks, and Hoists, ASA B30.2-1943, was createdfrom the eight-page document referred to in the first paragraph. This document was reaffirmedin 1952 and widely accepted as a safety standard.Due to changes in design, advancement in techniques,
24、 and general interest of labor and industryin safety, the Sectional Committee, under the joint sponsorship of ASME and the Naval FacilitiesEngineering Command, U.S. Department of the Navy, was reorganized as an American NationalStandards Committee on January 31, 1962, with 39 members representing 27
