20、d 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 present

21、ed 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 Engineer

22、ing 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 Manufact

23、urers 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 organizations to appoint representat

24、ives 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 published by ASME in 1916 as aba

25、sis, 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 requirementsfor jacks a separate code. In

26、 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, advancement in techniques, and gener

27、al 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 change

28、d 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 included in the scope of the ASA B

29、30.2. 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 ANSI in 1969, which resulted in B3

30、0 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 the American National StandardsIns

31、titute.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 accident prevention aregiven both as

32、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 requirements or permit the use ofo

33、ther 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, in accordancewith the format des

34、cribed 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 environmentaland industry needs. R

35、evisions 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 1975, 1984, 1990, 1996, 2004, and 20

36、09, 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 added in that edition. The 2012 editi

37、on was a complete rewrite of the2009 edition and included many new subjects and requirements updated to reflect the changingwork environment in which tower cranes operate. Major changes were made to the scope ofwork for erecting, dismantling, and climbing and takes into account wind zone regions acr

38、ossthe United States. Strength and stability requirements were modified to align with the newEuropean standard EN 14439. This 2016 Edition includes minor revisions throughout the book,including the addition of personnel competence.The edition of the B30.3 Volume was approved by the B30 Committee and

39、 by ASME, and wasapproved by ANSI and designated as an American National Standard on February 3, 2016.viASME 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

46、3-0.1: SCOPE OF B30.3Within the general scope of the B30 Standard, asdefined in Section I of the B30 Standard Introduction,the B30.3 Volume applies to “construction tower cranes”and “permanently mounted tower cranes” that are pow-ered by electric motors or internal combustion enginesand that adjust

47、their operating radius by means of aluffing boom mechanism, a trolley traversing a hori-zontal jib, or a combination of the two. The cranes maybe mounted on “fixed bases” or “traveling bases” andmay have tower and supporting structure arrangementsthat permit the crane to climb in a structure being b

48、uiltor that permits increasing the cranes tower height asthe structure rises. Variations of the above physical char-acteristics that provide the same fundamental operatingcharacteristics are included in the scope of this Volume;however, the requirements of this Volume are only appli-cable to the cra

49、nes within this scope when they areused in lifting operations. Mobile cranes configured withtower attachments (refer to ASME B30.5) andself-erecting tower cranes (refer to ASME B30.29) arenot within the scope of this Volume.SECTION 3-0.2: DEFINITIONS3-0.2.1 Types of Cranes3-0.2.1.1 By Type of Applicationconstruction tower crane: a hammerhead, luffing, or othertype of tower crane that is regularly assembled anddisassembled for use at various sites. It is usually charac-terized by provisions to facilitate erection and disman-tling and may include features to permit climbing or
