14、l Standard, Safety Standard for Cableways, Cranes, Derricks, Hoists,Hooks, Jacks, and Slings, has been developed under the procedures accredited by the AmericanNational Standards Institute (ANSI) (formerly the United States of America Standards Institute).This Standard had its beginning in December

15、1916 when an eight-page Code of Safety Standardsfor Cranes, prepared by an ASME Committee on the Protection of Industrial Workers, waspresented at the annual meeting of ASME.Meetings and discussions regarding safety on cranes, derricks, and hoists were held from 1920to 1925, involving the ASME Safet

16、y 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 theUSA Standards Institute), Department of Labor State of New Jersey, D

17、epartment 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, B

18、ureau 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, and the committee organized November 4, 1926, with 57 membe

19、rs 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 as a safety standard.Due to changes in design, advancement i

20、n 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 NationalStandards Committee on January 31, 1962, with 39 members re

21、presenting 27 nationalorganizations.The format of the previous code was changed so that separate Volumes (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 Commit

22、tee was reorganized as an Accredited Organization Committee, operatingunder procedures developed by ASME and accredited by ANSI.This Standard presents a coordinated set of rules that may serve as a guide to governmentand other regulatory bodies and municipal authorities responsible for the guarding

23、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 requiredby employers of their employees.In case of practical difficulties, new developments, or unnecessary ha

24、rdship, 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 interpretation of this St

25、andard,administrative or regulatory authorities are urged to consult the B30 Committee, in accordancewith the format described in Section IX of the B30 Standard Introduction, before renderingdecisions on disputed points.Safety codes and standards are intended to enhance public safety. Revisions resu

26、lt 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 2011 Edition of B30.7 is a complete rewrite of the Standard, and the title has changedfrom Base-Mount

27、ed Drum Hoists to Winches. Revisions were made to reflect current technology andteminology; this revision now addresses both vertical lifting and horizontal pulling applications. Inivaddition, changes have been made to update Chapters 7-2 and 7-3 to be more consistent withother B30 volumes.This Volu

28、me of the Standard, which was approved by the B30 Committee and by ASME, wasapproved by ANSI and designated an American National Standard on June 28, 2011.vASME B30 COMMITTEESafety Standard for Cableways, Cranes, Derricks, Hoists,Hooks, Jacks, and Slings(The following is the roster of the Committee
