20、cks, and Slings, has been developed under the procedures accredited by the AmericanNational Standards Institute (ANSI). This Standard had its beginning in December 1916 whenan eight-page Code of Safety Standards for Cranes, prepared by an ASME Committee on theProtection of Industrial Workers, was pr

21、esented at the annual meeting of the 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 Eng

22、ineering StandardsCommittee (AESC) (later changed to American Standards Association (ASA), then to the UnitedStates of America Standards Institute (USASI), and finally to ANSI), Department of Labor State of New Jersey, Department of Labor and Industry State of Pennsylvania, and theLocomotive Crane M

23、anufacturers Association. On June 11, 1925, AESC approved the ASMESafety Code Correlating Committees recommendation and authorized the project with theU.S. Department of the Navy, Bureau of Yards and Docks, and ASME as sponsors.In March 1926, invitations were issued to 50 organizations to appoint re

24、presentatives 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 members representing29 national organizations. Commencing June 1, 1927, and using the eight-page code publishedby ASME in 19

25、16 as a basis, the Sectional Committee developed the Safety Code for Cranes,Derricks, and Hoists. The early drafts of this safety code included requirements for Jacks, but,due to inputs and comments on those drafts, the Sectional Committee decided in 1938 to makethe requirements for Jacks a separate

26、 code. In January 1943, ASA B30.2-1943 was publishedaddressing a multitude of equipment types and in August 1943, ASA B30.1-1943 was publishedjust addressing Jacks. Both documents were reaffirmed in 1952 and widely accepted as safetystandards.Due to changes in design, advancement in techniques, and

27、general interest of labor and industryin safety, the Sectional Committee, under the joint sponsorship of ASME and the Bureau of Yardsand Docks (now the Naval Facilities Engineering Command) was reorganized on January 31, 1962,with 39 members representing 27 national organizations. The new committee

28、changed the formatof ASA B30.2-1943 so that the multitude of equipment types it addressed could be published inseparate volumes that could completely cover the construction, installation, inspection, testing,maintenance, and operation of each type of equipment that was included in the scope of ASA B

29、30.2.This format change resulted in the initial publication of B30.3, B30.5, B30.6, B30.11 and B30.16being designated as Revisions of B30.2 with the remainder of the B30 volumes being publishedas totally new volumes. ASA changed its name to USASI in 1966 and to ANSI in 1969, whichresulted in B30 vol

30、umes from 1943 to 1968 being designated as either ASA B30, USAS B30, orANSI B30, depending on their date of publication.In 1982, the Committee was reorganized as an Accredited Organization Committee, operatingunder procedures developed by ASME and accredited by ANSI. This Standard presents a coordi-

31、nated set of rules that may serve as a guide to government and other regulatory bodies andmunicipal authorities responsible for the guarding and inspection of the equipment falling withinits scope. The suggestions leading to accident prevention are given both as mandatory andadvisory provisions; com

32、pliance with both types may be required by 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 whe

33、n 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 of the Introducti

34、on, before rendering decisions on disputedpoints.vSafety 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 ed

35、itions were inadequate.B30.20, Below the Hook Lifting Devices was first published in 1985, new editions were publishedin 1993, 1999, 2003, and 2006. In the 2010 edition, maintenance was made mandatory, definitionswere revised and other changes were made to improve clarity. This 2013 revision adds re

36、quirementsfor personnel competence, operating controls marking and inspection, translation of non-Englishdocumentation into English and updates to the definition of Duty Cycle to align with revisionsmade to BTH-1. In addition, responsibilities for Owners and Operators are defined for each pieceof eq
