18、ional 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 had its beginning in December 191

19、6 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 1920to 1925, involving the ASME Safe

20、ty 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 USAStandards Institute). Department of Labor State of New Jersey,

21、Department of 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,

22、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 organization of this Sectional Committee was sent out Octo-ber 2, 1926, and the committee organized November 4, 1926, with 57 me

23、mbers representing 29national organizations. The Safety Code for Cranes, Derricks, and Hoists, ASA B30.2-1943, wascreated from the eight-page document referred to in the first paragraph. This document wasreaffirmed in 1952 and widely accepted as a safety standard.Duetochangesindesign,advancementinte

24、chniques,andgeneralinterestoflaborandindustryin 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

25、27 nationalorganizations.The format of the previous code was changed so that separate standards (each complete as toconstruction and installation; inspection, testing, and maintenance; and operation) will cover thedifferent types of equipment included in the scope of B30.In 1982, the Committee was r

26、eorganized 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 governmentandotherregulatorybodiesandmunicipalauthoritiesrespo

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 developments

28、, 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 application and interp

29、retation 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 on disputed points.In the 2010 edition of this Volume, Chapters 2 and 3 were revised and Maintenance was movedto
