16、onal Standards Institute (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 ASME Committee on the Protection of Industrial Workers, waspresented at the annual meetin
17、g 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 StandardsCommittee (lat
18、er changed to American Standards Association 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 Engineering Standards Commit
19、tee 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 aSectional Committee. The ca
20、ll 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 document referred to in t
21、he 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 FacilitiesEngineering
22、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 installation; inspecti
23、on, testing, 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 ANSI.This Standard presents a coordinate
24、d 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 as both mandatory and advisory provisions; complia
25、nce 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 when it
26、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 of the B30 Standard In
27、troduction, 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 do not imply that pre
28、vious editions were inadequate.ivThe first edition of B30.7, entitled Base-Mounted Drum Hoists, was published in 1971. Neweditions were published in 1977, 1984, 1989, 1994, 2001, and 2006. In 2011, the Volume wascompletely rewritten, and the title was changed to Winches. This 2016 Edition includes c
29、hangesto update the Volume to clarify that capstans are not part of the B30.7 scope, be more consistentwith other B30 volumes, and add personnel competence requirements and responsibilities.This Volume of the Standard, which was approved by the B30 Committee and by ASME, wasapproved by ANSI and desi
30、gnated an American National Standard on August 3, 2016.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 OFFICERSB.
