ISO 11660-1:2008 クレーン—アクセス、ガード、拘束—パート1：一般 | ページ 2

Foreword

ISO (the International 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 established 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 standardization.

International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, 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 requires approval by at least 75 % of the member bodies casting a vote.

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 Cranes — Access, guards and restraints:

• Part 1: General
• Part 2: Mobile cranes
• Part 3: Tower cranes
• Part 5: Bridge and gantry cranes

1 Scope

This part of ISO 11660 establishes the general requirements for access to control stations and other areas of cranes as defined in ISO 4306-1, during normal operations, maintenance, inspection, erection, dismantling and emergency. It also deals with guards and restraints in general, concerning the protection of persons on or near the crane with regard to moving parts, falling objects or live parts.

The particular requirements relating to access, guards and restraints for the various types of cranes and lifting appliances are given in ISO 11660-2, ISO 11660-3 and ISO 11660-5.

In some cases, the particular requirements may not comply with the general requirements. Different dimensions can be permitted provided an equivalent degree of protection is achieved.
