18、o Load and Boom orMast Lowered 37ivFOREWORDThis 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 Standard
19、s 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 discussions regarding safety on cranes, derricks, an
20、d 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 Association and subsequently to the USASta
21、ndards 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 CodeCorrelating Committees recommendation and
22、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 Sectional Committee was sent outOctober 2, 1926
23、, and the committee organized 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 document wasreaffirmed in 1952 and widely accepted
24、 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 the Navy, was reorganized as an American Nation
25、alStandards 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, testing, and maintenance; and operation) will cover thedifferent type
26、s of equipment included 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
27、 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 with both types may be require
28、dby 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 clearly evident that an equival
29、ent 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 on disputed points.This Volu
30、me of the Standard contains revisions to all chapters. The most notable changesinclude the addition of responsibilities, hand signals, and more comprehensive information onoperation near electric power lines.This Volume was approved by the B30 Committee and by ASME, and was approved by ANSIand desig
31、nated as an American National Standard on September 20, 2010.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 changing environmentaland industry needs. Revisions do not imply that
32、 previous editions were inadequate.vASME B30 COMMITTEESafety Standard for Cableways, Cranes, Derricks, Hoists,Hooks, Jacks, and Slings(The following is the roster of the Committee at the time of approval of this Standard.)STANDARDS COMMITTEE OFFICERSP.
