The work of preparing International Standards is normally carried

8、 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

9、 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, Part 2.The main task of technical committees is to prepare International

10、 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.Attention is drawn to the possibility that some of the element

11、s of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.ISO 2328 was prepared by Technical Committee ISO/TC 110, Industrial trucks, Subcommittee SC 2, Safety of powered industrial trucks.This fourth edition cancels and r

16、he terms and definitions given in ISO 2331 and ISO 3691-1 apply.4 Requirements4.1 DimensionsThe 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 lower hook determining the type of fork arm) shall be in accordance with

17、 Figures 1, 2 and 3 and Tables 1 and 2. The fork arm removal/mounting slot on the lower fork carrier is optional and shall be in accordance with 4.3. Fork arm location slots to the dimensions specified in Table 2 shall be provided at a suitable spacing on the fork carrier. In order to locate attachm

18、ents, one slot shall be situated on the top edge of the fork carrier centreline. However, when an offset lower slot is provided to avoid unintentional disengagement, then the lower slot shall be offset from the fork carrier centreline by dimension w (see Figure 1); this slot shall be 3 mm deeper tha

19、n k2(see Figure 3), to facilitate the attachment and fork arm mounting.4.2 StopsStops shall be provided in order to prevent lateral disengagement of the fork arms from the extremities of the fork carrier. If these stops are not permanent, i.e. welded, then the instruction handbook shall contain warn

20、ings that the truck is not to be used if the stops are not correctly in place.4.3 Slot on the lower carriageIf a fork arm removal/mounting slot is provided in the lower edge of the fork carrier, it shall be positioned as shown in Figure 3, that shown in the detailed view XX being optional. If the po

21、sitioning of the slots in the upper and lower fork carrier could enable the fork arm or attachment to become inadvertently disengaged from the carrier, then other means (e.g. mechanical) shall be provided to prevent this from occurring.Where the exclusive means of preventing unintentional fork arm d

22、isengagement is by an offset lower slot, then the instruction handbook shall contain the following warning notice: ISO 2011 All rights reserved 1BS ISO 2328:2011WARNING If the fork/locking pin is not fully engaged, the fork could become unintentionally disengaged.Key1 carriage centreline2 upper hook
