21、mittees. ThisStandard had its beginning in June 1979 when the Jack Institute addressed the B30 Committeeon Cableways, Cranes, Derricks, Hoists, Hooks, Jacks, and Slings. The Jack Institute requestedthe B30 Committee either to develop a standard for automotive jacks or to include this equipmentas par
22、t of the revision of B30.1, Jacks. The B30 Committee declined this request.As a result, the Jack Institute petitioned ANSI in July 1979 for the formation of a committeeto promulgate safety and/or performance standards for portable automotive lifting devices,requesting the designation of ASME as spon
23、sor of the project.In September 1979, ASMEs Policy Board, Codes and Standards, approved sponsorship of thecommittee to operate under the procedures developed by ASME and accredited by ANSI. Anominating committee was appointed to recommend a proposed membership to the ASME SafetyCodes and Standards C
24、ommittee for approval. The membership was approved at the beginningof May 1980.The inaugural meeting of the ASME Committee on Portable Automotive Lifting Devices (PALD)was held in July 1980. The committee determined that the format of this Standard would be suchthat separate volumes, each complete a
25、s to design, marking, identification, testing, operation,inspection, and maintenance, would cover the different types of equipment included in the PALDscope. In the 1993 edition the various volumes were combined into one Standard with commonrequirements in one place and the information that is speci
26、fic to a particular type of equipmentset out in succeeding Parts. This allowed for greater consistency in requirements and eliminatedredundancy.The 1997 edition was a further revision and consolidation of the 1993 edition and includes aPart covering automotive ramps.The 2003 edition is a revision of
27、 the 1997 edition, and includes a Part covering forklift jacks.This Standard presents a coordinated set of rules that may serve as a guide to manufacturers,to government and other regulatory bodies, to municipal authorities, and to commercial usersresponsible for the inspection, maintenance, and ins
28、truction in the use of the equipment fallingwithin its scope.This edition of the Standard, which was approved by the ASME Committee on PortableAutomotive Lifting Devices and by ASME, was approved by ANSI and designated as an AmericanNational Standard on September 19, 2005.Safety codes and standards
29、are intended to enhance public health and safety. Revisions resultfrom committee consideration of factors such as technological advances, new data, and changingenvironmental and industry needs. Revisions do not imply that previous editions were inadequate.v(05)Copyright ASME International Provided b
