36、erly 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 ASME.Meetings and discussion
37、s 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 changed to American Standards
38、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 approved the ASME Safety Code
39、Correlating 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 organization of this Secti
40、onal Committee was sent out October 2,1926, and the committee organized on November 4, 1926, with 57 members representing29 national organizations. The Safety Code for Cranes, Derricks, and Hoists, ASA B30.2-1943,was created from the eight-page document referred to in the first paragraph. This docum
41、ent wasreaffirmed in 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.S. Department of th
42、e 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 volumes (each complete as toconstruction and installation; inspection, testing, and maintenance;
43、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 Standard presents a coor
44、dinated 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 advisory provisions; c
45、ompliance 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 or methods, but only wh
46、en 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 Section IX, before renderin
47、g decisions on disputed points.Operation and maintenance instructions in this safety Standard are intended for generalapplications.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
48、 changing environmentaland industry needs. Revisions do not imply that previous editions were inadequate. The 2010edition of this Volume contains minor revisions throughout.Following approval by the B30 Standards Committee and the ASME Board, ASME B30.9-2010was approved as an American National Stand
