6 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 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 (later changed to American Standards Association and subsequently to the USAS tandards Institute). Department of Labor State of New Jersey, Department of Labor andIndustry State of Pennsylvania, and the Locomotive crane Manufacturers Association.

7 OnJune 11, 1925, the American Engineering Standards Committee approved the ASME Safety CodeCorrelating Committee s recommendation and authorized the project with the Departmentof the Navy, Bureau of Yards and Docks, and ASME as March 1926, invitations were issued to 50 organizations to appoint representatives to aSectional Committee. The call for organization of this Sectional Committee was sent out October2, 1926, and the committee organized November 4, 1926, with 57 members representing 29 nationalorganizations. The Safety Code for Cranes , Derricks, and Hoists, ASA , was createdfrom the eight-page document referred to in the first paragraph. This document was reaffirmedin 1952 and widely accepted as a safety 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, Department of the Navy, was reorganized as an American NationalStandards Committee on January 31, 1962, with 39 members representing 27 format of the previous code was changed so that separate standards (each complete as toconstruction and installation; inspection, testing, and maintenance.)

8 And operation) will cover thedifferent types of equipment included in the scope of 1982, the Committee was reorganized as an Accredited Organization Committee, operatingunder procedures developed by the ASME and accredited by the American National 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 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 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 equivalent degree ofprotection is thereby secured.

9 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 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 previous editions were this Volume of the Standard, Chapter 2-3 has been revised and Maintenance has been movedto a new Chapter 2-4. This Standard was approved by the B30 Committee and by ASME, wasapproved by ANSI and designated as an American National Standard on May 31, B30 STANDARDS COMMITTEES afety 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.)
