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
25、 national organiza-tions.The format of the previous code was changed so that separate standards (each complete as toconstruction and installation; inspection, testing, and maintenance; and operation) would coverthe different types of equipment included in the scope of B30.In 1982, the Committee was
26、reorganized as an Accredited Organization Committee, operatingunder procedures developed by the ASME and accredited by the American National StandardsInstitute.This Standard presents a coordinated set of rules that may serve as a guide to governmentand other regulatory bodies and municipal authoriti
27、es responsible for the guarding and inspectionof the equipment falling within its scope. The suggestions leading to accident prevention aregiven both as mandatory and advisory provisions; compliance with both types may be requiredby employers of their employees.In case of practical difficulties, new
28、 developments, or unnecessary hardship, the administrativeor regulatory authority may grant variances from the literal requirements or permit the use ofother devices or methods, but only when it is clearly evident that an equivalent degree ofprotection is thereby secured. To secure uniform applicati
29、on and interpretation of this Standard,administrative or regulatory authorities are urged to consult the B30 Committee, in accordancewith the format described in Section III, before rendering decisions on disputed points.This volume of the Standard, which was approved by the B30 Standards Committee
30、and byASME, was approved by ANSI and designated as an American National Standard on February19, 2003.Safety codes and standards are intended to enhance public safety. Revisions result from commit-tee consideration of factors such as technological advances, new data, and changing environmentaland ind
31、ustry needs. Revisions do not imply that previous editions were inadequate.ivCopyright ASME International Provided by IHS under license with ASMENot for ResaleNo reproduction or networking permitted without license from IHS-,-ASME B30 STANDARDS COMMITTEESafety Standards for Cableways, Cranes, Derric
