32、al Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been e
33、stablished has the right to be represented on that committee. 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 standard
34、ization. International Standards are drafted in accordance 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 vo
35、ting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all su
36、ch patent rights. ISO 11660-1 was prepared by Technical Committee ISO/TC 96, Cranes, Subcommittee SC 7, Tower cranes. This second edition cancels and replaces the first edition (ISO 11660-1:1999), which has been technically revised. ISO 11660 consists of the following parts, under the general title

The particular requirements relating to access, guards and restraints
40、for the various types of cranes and lifting appliances are given in the other parts of ISO 11660. In some cases, the particular requirements may not comply with the general requirements.
