31、andard, Safety Standard for Cableways, Cranes, Derricks, Hoists, Hooks, Jacks, and Slings, has been developed under the procedures accredited by the American National Standards Institute (ANSI). This Standard had its beginning in December 1916 when an eight-page “Code of Safety Standards for Cranes,

32、 ” prepared by an ASME Committee on the Protection 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 1920 to 1925, involving the ASME Safety Code Correlating Committee, the Association of I

33、ron and Steel Electrical Engineers, the American Museum of Safety, the American Engineering Standards Committee (AESC) later changed to American Standards Association (ASA), then to the United States of America Standards Institute (USASI), and finally to ANSI, Department of Labor State of New Jersey

34、, Department of Labor and Industry State of Pennsylvania, and the Locomotive Crane Manufacturers Association. On June 11, 1925, AESC approved the ASME Safety Code Correlating Committees recommendation and authorized the project with the U.S. Department of the Navy, Bureau of Yards and Docks, and ASM

35、E as sponsors. In March 1926, invitations were issued to 50 organizations to appoint representatives to a Sectional Committee. The call for organization of this Sectional Committee was sent out October 2, 1926, and the committee organized November 4, 1926, with 57 members representing 29 national or

36、ganizations. Commencing June 1, 1927, and using the eight-page code published by ASME in 1916 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 t

37、hose drafts, the Sectional Committee decided in 1938 to make the requirements for jacks a separate code. In January 1943, ASA B30.2-1943 was published addressing a multitude of equipment types, and in August 1943, ASA B30.1-1943 was published just addressing jacks. Both documents were reaffirmed in

38、1952 and widely accepted as safety standards. Due to changes in design, advancement in techniques, and general interest of labor and industry in safety, the Sectional Committee, under the joint sponsorship of ASME and the Bureau of Yards and Docks (now the Naval Facilities Engineering Command), was

39、reorganized on January 31, 1962, with 39 members representing 27 national organizations. The new Committee changed the format of ASA B30.2-1943 so that the multitude of equipment types it addressed could be published in separate volumes that could completely cover the construction, installation, ins

40、pection, testing, main- tenance, and operation of each type of equipment that was included in the scope of ASA B30.2. This format change resulted in the initial publication 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

41、 published as totally new volumes. ASA changed its name to USASI in 1966 and to ANSI in 1969, which resulted in B30 volumes from 1943 to 1968 being designated as either “ ASA B30, ” “USAS B30, ” or “ ANSI B30” depending on their date of publication. In 1982, the Committee was reorganized as an Accre

42、dited Organization Committee, operating under procedures developed by ASME and accredited by ANSI. This Standard presents a coordinated set of rules that may serve as a guide to government and other regulatory bodies and municipal authorities responsible for the guarding and inspection of the equipm

43、ent falling within its scope. The suggestions leading to accident prevention are given both as mandatory and advisory provisions; compliance with both types may be required by employers of their employees. In case of practical difficulties, new developments, or unnecessary hardship, the administrati

44、ve or regulatory authority may grant variances from the literal requirements or permit the use of other devices or methods, but only when it is clearly evident that an equivalent degree of protection is thereby secured. To secure uniform application and interpretation of this Standard, administrativ

45、e or regulatory authorities are urged to consult the B30 Committee, in accordance with the format described in Section IX of the Introduction, before rendering decisions on disputed points. Safety codes and standards are intended to enhance public safety. Revisions result from committee consideratio

46、n of factors such as technological advances, new data, and changing environmental and industry needs. Revisions do not imply that previous editions were inadequate. The first edition of B30.25 was issued in 1998, and new editions were released in 2003 and 2007. The 2013 edition added a section in Ch

47、apter 25-0 to define personnel competence, added personnel responsibilities to Chapter 25-3, and included many additional minor revisions throughout. This edition changes some of the nomenclature to better reflect the terminology that is currently used throughout the industries that utilize this equ

48、ipment. Other minor editorial changes have been made to bring this Volume up to current standards. This Volume of the Standard, which was approved by the B30 Committee and by ASME, was approved by ANSI and designated as an American National Standard on June 8, 2018. vASME B30 COMMITTEE SafetyStandar
