12、 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
13、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 matter
14、s of electrotechnical standardization. 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 circulat
15、ed to the member bodies for voting. 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
16、 for identifying any or all such patent rights. ISO 22915-3 was prepared by Technical Committee ISO/TC 110, Industrial trucks, Subcommittee SC 2, Safety of powered industrial trucks. This first edition of ISO 22915-3 cancels and replaces ISO 3184:1998, of which it constitutes a technical revision. I
17、t also incorporates the Technical Corrigendum ISO 3184:1998/Cor.1:2000.

23、08(E) ISO 2008 All rights reserved 1 Industrial trucks Verification of stability Part 3: Reach and straddle trucks 1 Scope This part of ISO 22915 specifies the tests for verifying the stability of reach trucks (with retractable mast or fork) and straddle trucks, equipped with tilting or non-tilting
24、masts or fork arms and having a rated capacity up to and including 5 000 kg. It is also applicable to such trucks operating under the same conditions when equipped with load-handling attachments. 2 Normative references The following referenced documents are indispensable for the application of this

32、 tilt table of the point of intersection between the centreline of the drive/steer axle and the centreline of the drive wheel width. c) For trucks with a drive/steer axle in an articulating frame articulated in the centre plane of the truck: point M shall be the vertical projection onto the tilt tab
33、le of the point of the intersection between the lateral axis of the articulating frame and the centre plane, AA, of the truck. d) For trucks with a sprung castor wheel and a single non-sprung drive (steer) wheel: point M shall be the vertical projection onto the tilt table of the point of intersecti
34、on between the centreline of the drive wheel axle and the centreline of the drive wheel width, with the axle of the drive wheel positioned at right angles to the tilt axis.
