20、 Derricks, Hoists,Hooks, Jacks, 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
21、of Industrial Workers, was presented 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 Museu
22、m of Safety, the American Engineering 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
23、, and theLocomotive Crane Manufacturers Association. On June 11, 1925, AESC approved the ASME SafetyCode Correlating Committees recommendation and authorized the project with the U.S.Department of the Navy Bureau of Yards and Docks and ASME as sponsors.In March 1926, invitations were issued to 50 or
24、ganizations to appoint representatives 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 cod
25、e published by ASME in 1916 as abasis, 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 andcomments on those drafts, the Sectional Committee decided in 1938 to make the require
26、mentsfor jacks a separate code. In January 1943, ASA B30.2-1943 was published, addressing a multitudeof equipment types, and in August 1943, ASA B30.1-1943 was published, just addressing jacks.Both documents were reaffirmed in 1952 and widely accepted as safety standards.Due to changes in design, ad
27、vancement in techniques, and 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 orga
28、nizations.The new Committee changed the format of ASA B30.2-1943 so that the multitude of equipmenttypes it addressed could be published in separate volumes that could completely cover theconstruction, installation, inspection, testing, maintenance, and operation of each type of equip-ment that was
29、included in the scope of the ASA B30.2. This format change resulted in the initialpublication of B30.3, B30.5, B30.6, B30.11, and B30.16 being designated as “Revisions” of B30.2,with the remainder of the B30 volumes being published as totally new volumes. ASA changedits name to USASI in 1966 and to
30、ANSI in 1969, which resulted in B30 volumes from 1943 to1968 being designated as either ASA B30, USAS B30, or ANSI B30, depending on their date ofpublication.In 1982, the Committee was reorganized as an Accredited Organization Committee, operatingunder procedures developed by ASME and accredited by
31、the American National StandardsInstitute.This 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 acc
32、ident prevention aregiven both as mandatory and advisory 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
33、requirements or permit the use ofother devices or methods, but only when it is clearly evident that an equivalent degree ofprotection is thereby secured. To secure uniform application and interpretation of this Standard,vadministrative or regulatory authorities are urged to consult the B30 Committee
34、, in accordancewith the format described in Section IX of the Introduction, before rendering decisions on disputedpoints.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
35、environmentaland industry needs. Revisions do not imply that previous editions were inadequate.The first edition of B30.3 Construction Tower Cranes was published in 1975 as a “partialrevision” to B30.2-1943 (R1952) and was the first volume dedicated to tower cranes. New editionswere published, in 19
36、75, 1984, 1990, 1996, 2004, and 2009, with the 2009 edition revising the titleof B30.3 to Tower Cranes and reflecting the revised scope that now included both construction andpermanently mounted tower cranes (formerly addressed in B30.4). Responsibilities for members ofthe lifting team were also add
37、ed in that edition. This 2012 edition includes major changes andadditions to the scope of work for erecting, dismantling, and climbing, and takes into accountwind zone regions across the United States. Strength and stability requirements have also beenmodified to align with the new European standard
38、 EN 14439. The inspection section now includesrequirements for “Major Inspections” that are to be conducted at 60-month intervals. This editionis a complete rewrite of the 2009 edition and includes many new subjects and requirementsupdated to reflect the changing work environment in which tower cran
39、es operate.The edition of the B30.3 Volume was approved by the B30 Committee and by ASME, and wasapproved by ANSI and designated as an American National Standard on December 21, 2012.viASME B30 COMMITTEESafety Standard for Cableways, Cranes, Derricks, Hoists,Hooks, Jacks, and Slings(The following is
