12、ommittee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in acco
13、rdance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requi

20、ved 1 Cranes Requirements for mechanisms Part 3: Tower cranes 1Scope This part of ISO 10972 establishes requirements which apply specifically to the mechanisms and related components of tower cranes, in addition to the general requirements given in ISO 10972-1. These additional requirements concern
21、a)the arrangement, features and characteristics of the crane mechanisms, and b)the minimum requirements for certain mechanism components. Rules for the proof of competence calculation regarding different limit states (yield strength, fatigue, wear) are excluded from this part of ISO 10972. This part
22、 of ISO 10972 is not applicable to the climbing mechanisms and related components used on tower cranes, nor to the climbing frame. 2Normative references The following referenced documents are indispensable for the application of this document.
