19、 license 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
20、Standards Institute (formerly the United States of America Standards Institute). ThisStandard had 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 ASM
21、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
22、ed to American Standards Association and subsequently to the USAStandards Institute), Department of LaborState of New Jersey, Department of Labor andIndustryState of Pennsylvania, and the Locomotive Crane Manufacturers Association. On June11, 1925, the American Engineering Standards Committee approv
23、ed 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 org
24、anization 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 first p
25、aragraph. 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, U
26、.S. Department of the Navy, was reorganized as an American NationalStandards Committee on January 31, 1962, with 39 members representing 27 national organiza-tions.The format of the previous code was changed so that separate volumes (each complete as toconstruction and installation; inspection, test
27、ing, and maintenance; and operation) would coverthe different 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 the American National StandardsInstitute.This St
28、andard presents a coordinated set 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
29、advisory provisions; compliance with 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 o
30、r methods, but only when it is clearly 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 Secti
31、on IX, before rendering decisions on disputed points.The 2009 edition of this Volume revised its scope to include Construction and PermanentlyMounted Tower Cranes and added the responsibilities of other members of the lifting team.Safety codes and standards are intended to enhance public safety. Rev
32、isions result from commit-tee consideration of factors such as technological advances, new data, and changing environmentaland industry needs. Revisions do not imply that previous editions were inadequate.This Volume of the Standard, which was approved by the B30 Committee and by ASME, wasapproved b
33、y ANSI and designated as an American National Standard on July 27, 2009.vCopyright ASME International Provided by IHS under license with ASME Not for ResaleNo reproduction or networking permitted without license from IHS-,-,-ASME B30 COMMITTEESafety Standards for Cableways, Cranes, Derricks, Hoists,
