28、S-,-,-FOREWORDThis American National Standard, 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 ha
29、d its beginning in December 1916 when an eight-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 1920t
30、o 1925, involving the ASME Safety Code Correlating 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 USA Stan-dards Institute), Departme
31、nt of Labor State of New Jersey, Department of Labor and Industry State of Pennsylvania, and the Locomotive Crane Manufacturers Association. On June 11, 1925,the American Engineering Standards Committee approved the ASME Safety Code CorrelatingCommittees recommendation and authorized the project wit
32、h the U.S. Department of the Navy,Bureau of Yards and Docks, and ASME as sponsors.In March 1926, invitations were issued to 50 organizations to appoint representatives to a Sec-tional Committee. The call for organization of this Sectional Committee was sent out October 2,1926, and the committee orga
33、nized November 4, 1926, with 57 members representing 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.Du
34、e to changes in design, advancement in techniques, and general interest of labor and in-dustry in safety, the Sectional Committee, under the joint sponsorship of ASME and the NavalFacilities Engineering Command, U.S. Department of the Navy, was reorganized as an Ameri-can National Standards Committe
35、e on January 31, 1962, with 39 members representing 27 na-tional organizations.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 in
36、cluded in the scope of B30.In 1982, the Committee was 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 governm
37、ent andother regulatory bodies and municipal authorities responsible for the guarding and inspection ofthe equipment falling within its scope. The suggestions leading to accident prevention are givenboth as mandatory and advisory provisions; compliance with both types may be required by em-ployers o
38、f their employees.In case of practical difficulties, new developments, or unnecessary hardship, the administra-tive or regulatory authority may grant variances from the literal requirements or permit the useof other devices or methods, but only when it is clearly evident that an equivalent degree of
39、 pro-tection is thereby secured. To secure uniform application and interpretation of this Standard, ad-ministrative or regulatory authorities are urged to consult the B30 Committee, in accordance withthe format described in Section III, before rendering decisions on disputed points.This volume of th
40、e Standard, which was approved by the B30 Committee and by ASME, wasapproved by ANSI and designated as an American National Standard on August 29, 2005.Safety codes and standards are intended to enhance public safety. Revisions result from com-mittee consideration of factors such as technological ad
41、vances, new data, and changing environ-mental and industry needs. Revisions do not imply that previous editions were inadequate.ivCopyright ASME International Provided by IHS under license with ASME Not for ResaleNo reproduction or networking permitted without license from IHS-,-,-ASME B30 STANDARDS
