1 Scope

GB/T 12932-2010 is the Chinese national standard on shipbuilding-jib cranes, in the field of shipbuilding and marine structures. The /T suffix marks it as a recommended standard: it is not compulsory by itself, but it becomes binding as soon as a contract, a tender or a customer specification calls it up - which in practice is how most foreign buyers meet it. It was issued on 9 August 2010 by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China; Standardization Administration of China, and has been in force since 1 December 2010. Classification: ICS 47.020.40, CCS U22. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This standard specifies the marine crane jib (hereinafter referred to as "Crane") requirements, inspection rules, classification and labels. This standard applies to driven by an electric or hydraulic loading and unloading with a crane arm frame (or the job in Port of offshore wind is not more than Pu S 2 waters) design acceptance. This standard does not apply to electromagnetic and grab cranes, offshore cranes and groceries platform, davits and other auxiliary working crane design acceptance.
