7、 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 est
8、ablished 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 standardiz
9、ation. 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 voti
10、ng. 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 such
11、 patent rights. ISO 2328 was prepared by Technical Committee ISO/TC 110, Industrial trucks, Subcommittee SC 2, Safety of powered industrial trucks. This third edition cancels and replaces the second edition (ISO 2328:1993), which has been technically revised. -,-,- INTERNATIONAL STANDARD ISO 2328:20

15、he terms and definitions given in ISO 2331 and ISO 3691 and the following apply. 4 Requirements 4.1 Dimensions The mounting dimensions of the fork arms and fork carrier for type A (short drop) and type B (long drop) fork arms (the position of the bottom hook determining the type of fork) shall be in
16、 accordance with Figures 1, 2 and 3 and Tables 1 and 2. Fork arm location slots to the dimensions specified in Table 2 shall be provided at a suitable spacing on the fork arm carriage. In order to locate attachments, one slot shall be situated on the top edge of the carrier plate centreline. However
17、, when an offset lower slot is provided to avoid unintentional disengagement, then the top central slot shall be offset by dimension w (see Figure 1); this slot shall be 3 mm deeper, to facilitate the attachment and fork arm mounting.

If these stops are not permanent, i.e. welded, then the instruction handbook shall contain warnin
19、gs that the truck is not to be used if the stops are not correctly in place. 4.3 Slot on the lower carriage If a fork arm removal/mounting slot is provided in the lower edge of a carriage, it shall be positioned as shown in Figure 3, that shown in the detailed view X being optional. If the positioni
