New product
ASME B30.9-2014 Slings
standard by ASME International, 02/06/2015
Full Description
ASME has been defining crane safety since 1916.Volume B30.9 includes provisions that apply to slings used for load handling purposes, used in conjunction with equipment described in other volumes of the B30 Standard, except as restricted in B30.12 and B30.23. Slings fabricated from alloy steel chain, wire rope, metal mesh, polyester fiber rope, synthetic webbing, and synthetic fiber yarns in a protective cover(s) are addressed.
This safety standard offers comprehensive solutions applying to the fabrication, attachment, use, inspection, testing and maintenance of this equipment used for lifting purposes.
B30.9 is to be used in conjunction with equipment described in other volumes of the ASME B30 series of safety standards.
Careful application of B30 safety standards will help users to comply with applicable regulations within their jurisdictions, while achieving the operational and safety benefits to be gained from the many industry best-practices detailed in these volumes.
Intended for manufacturers, owners, employers, users and others concerned with the specification, buying, maintenance, training and safe use of slings and hooks with B30 equipment, plus all potential governing entities.

FOREWORD
This American National Standard, 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, prepared by the ASME Committee on the Protection of Industrial Workers, was presented to 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 Iron and Steel Electrical Engineers, the American Museu
