18、(ANSI, formerly the United States of America Standards Institute).This Standard had its beginning in December 1916 when an eight-page Code of Safety Standardsfor Cranes, prepared by an American Society of Mechanical Engineers (ASME) Committee onthe Protection of Industrial Workers, was presented at
19、the annual meeting of ASME.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 Standa
20、rdsCommittee later changed to American Standards Association (ASA), and subsequently to theUSA Standards 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 Engine
21、ering Standards Committee approved 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 aSecti
22、onal Committee. The call for organization of this Sectional Committee was sent outOctober 2, 1926, 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 doc
23、ument referred to in the first paragraph. This document 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
24、FacilitiesEngineering Command, U.S. Department of the 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
25、installation; inspection, testing, and maintenance; and operation) will cover thedifferent 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 ANSI.This Standard
26、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 advisor
27、y 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 or metho
28、ds, 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 Section IX o
29、f the B30 Standard Introduction, before renderingdecisions on disputed points.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
30、do not imply that previous editions were inadequate.The 2012 edition of this Standard includes a major revision to Chapter 16-2 and the additionof Chapter 16-4. The sections on maintenance of hoist components in Chapter 16-2 have beenmoved to Chapter 16-4, along with other updates to the Standard. T
31、his Volume of the Standard,which was approved by the B30 Standards Committee and by ASME, was approved by ANSIand designated as an American National Standard on September 5, 2012.ivASME B30 COMMITTEESafety Standard for Cableways, Cranes, Derricks, Hoists,Hooks, Jacks, and Slings(The following is the
