19、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 presented at the annual
20、 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 Engineering StandardsCom
21、mittee (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 theLocomotiveCraneManufacturersAssociation.O
22、nJune11,1925,AESCapprovedtheASMESafetyCode 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 representatives to aSectional Committ
23、ee. 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 1916 as a basis, the Sectional Commit
24、tee 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 code. In January 1943, ASA B30.2-1
25、943 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.Duetochangesindesign,advancementintechniques,andgeneralinterestoflaborandindustryin safety,
26、 the Sectional Committee, under the joint sponsorship of ASME and the Bureau of YardsandDocks(nowtheNavalFacilitiesEngineeringCommand),wasreorganizedonJanuary31,1962,with 39 members representing 27 national organizations. The new committee changed the formatof ASA B30.2-1943 so that the multitude of
27、 equipment types it addressed could be published inseparate volumes that could completely cover the construction, installation, inspection, testing,maintenance,andoperationofeachtypeofequipmentthatwasincludedinthescopeofASAB30.2.This format change resulted in the initial publication of B30.3, B30.5,
28、 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 volumes from 1943 to 1968 being designated as either ASA B30, USAS B30, orANS
29、I 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-nated set of rules that may serve as a guide to government and other regul
30、atory 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 andadvisoryprovisions;compliancewithbothtypesmayberequiredbyemployersoftheiremployees.In case of prac
31、tical difficulties, new developments, or unnecessary hardship, the administrativeor regulatory authority may grant variances from the literal requirements or permit the use ofotherdevicesormethodsbutonlywhenitisclearlyevidentthatanequivalentdegreeofprotectionis thereby secured. To secure uniform app
32、lication and interpretation of this Standard, administra-tive or regulatory authorities are urged to consult the B30 Committee, in accordance with theformat described in Section IX of the Introduction, before rendering decisions on disputed points.vSafetycodesandstandardsareintendedtoenhancepublicsa

Revisions do not imply that previous editions were inadequate.B30.4 has been in existence since 1943. New editions were published in 1973 and 1981 underthe title Po

For the 2010 Edition, B30.4 removed all referencesto tower cranes and revised the title to Portal and Pedestal Cranes. All requirements for towercranes were incorporate
35、d into B30.3-2009. This 2015 Edition contains technical and editorialrevisions, including the addition of responsibilities of personnel, personnel competence, andtranslations.This Volume of the Standard, which was approved by the B30 Committee and by ASME, wasapproved by ANSI and designated as an Am
