16、ense with ASME Not for ResaleNo reproduction or networking permitted without license from IHS-,-,-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 Stan
17、dards Institute (ANSI) (formerly the United States of America Standards Institute).This Standard had its beginning in December 1916, when an eight-page Code of Safety Standardsfor Cranes, prepared by an ASME Committee on the Protection of Industrial Workers, waspresented to the annual meeting of ASM
18、E.Meetings and discussions regarding safety on cranes, derricks, and hoists were held from 1920to 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 chang
19、ed to American Standards Association and subsequently to the USAStandards Institute), Department of Labor State of New Jersey, Department of Labor andIndustry State of Pennsylvania, and the Locomotive Crane Manufacturers Association. OnJune 11, 1925, the American Engineering Standards Committee appr
20、oved the ASME Safety CodeCorrelating Committees recommendation and authorized the project, with the U.S. Departmentof the Navy, Bureau of Yards and Docks, and ASME as sponsors.In March 1926, invitations were issued to 50 organizations to appoint representatives to aSectional Committee. The call for
21、organization of this Sectional Committee was sent out October2, 1926, and the committee organized 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 firs
22、t paragraph. This document was reaffirmedin 1952 and widely accepted as a safety standard.Due to changes in design, advancement in techniques, and general interest of labor and industryin safety, the Sectional Committee, under the joint sponsorship of ASME and the Naval FacilitiesEngineering Command
23、, U.S. Department of the Navy, was reorganized as an American NationalStandards Committee on January 31, 1962, with 39 members representing 27 nationalorganizations.The format of the previous code was changed so that separate standards (each complete as toconstruction and installation; inspection, t
24、esting, and maintenance; and operation) will cover thedifferent types of equipment included in the scope of B30.In 1982, the Committee was reorganized as an Accredited Organization Committee, operatingunder procedures developed by ASME and accredited by ANSI.This Standard presents a coordinated set
25、of rules that may serve as a guide to governmentand other regulatory bodies and municipal authorities 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 wi
26、th both types may be requiredby employers of their employees.In case of practical difficulties, new 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 cle
27、arly evident that an equivalent degree ofprotection is thereby secured. To secure uniform application and interpretation of this Standard,administrative or regulatory authorities are urged to consult the B30 Committee, in accordancewith the format described in Section IX, before rendering decisions
28、on disputed points.This Volume of the Standard, which was approved by the B30 Committee and by ASME, wasapproved by ANSI and designated as an American National Standard on January 25, 2008.Safety codes and standards are intended to enhance public safety. Revisions result from commit-tee consideratio
29、n of factors such as technological advances, new data, and changing environmentaland 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 lice
