11、 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
12、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 acc
13、ordance 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 voting. Publication as an International Standard requ
14、ires 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 patent rights. ISO 22915-21 was prepared by Tech
15、nical Committee ISO/TC 110, Industrial trucks, Subcommittee SC 2, Safety of powered industrial trucks.

21、ies the tests for verifying the stability of order-picking trucks with an elevating operator position, as defined in ISO 5053, where the operators position can be raised to an elevation above 1 200 mm. It is applicable to industrial trucks fitted with fork arms, platforms and/or integrated attachmen
22、ts under normal operating conditions. It is not applicable to trucks fitted with a load carrier that can be shifted laterally or pivoted out of the trucks longitudinal centre plane. 2 Normative references The following referenced documents are indispensable for the application of this document.

27、 travel direction 3.4 unrestricted steering steering mode controlled by the operator with no limitation of the steering angle 4 Test conditions 4.1 General See ISO 22915-1. 4.2 Position of truck on tilt table 4.2.1 Load and drive/steer axles The load axle and the drive/steer axle are defined by Figu
28、re 1. Key AA longitudinal centre plane of truck BB drive/steer axle CC load axle Figure 1 Load and drive/steer axles 4.2.2 Test 1 The truck shall be positioned on the tilt table so that its drive/steer axle, BB, and load axle, CC, are parallel to the tilt axis, XY, of the tilt table. See Table 1. 4.
29、2.3 Tests 2, 3, 4 and 5 The truck shall be positioned on the tilt table with the line, MN, parallel to the tilt axis, XY, of the tilt table. See Table 1. Point M is defined as follows. a) For trucks with a single drive (steer) wheel: point M shall be the vertical projection onto the tilt table of th
30、e point of intersection between the centreline of the drive/steer axle and the centreline of the drive wheel width. b) 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 table of the point o
31、f intersection between the lateral axis of the articulating frame and the centre plane, AA, of the truck. BS ISO 22915-21:2009ISO 22915-21:2009(E) ISO 2009 All rights reserved 3c) For trucks with dual drive (steer) wheels: point M shall be the vertical projection onto the tilt table of the point of
32、intersection between the centreline of the drive/steer axle and the centre plane, AA, of the truck. d) For trucks with non-articulated, non-sprung castors: point M shall be the vertical projection onto the tilt table of the point of intersection between the centreline of the castor wheel width, with
33、 the non-sprung castor positioned with the centreline of the castor wheel axle nearer to the centre plane of the truck. e) For trucks with non-articulated, non-sprung castors or wheels and a non-articulated drive wheel: 1) for the non-sprung castor or wheel, point M shall be the vertical projection
34、onto the tilt table of the point of intersection between the centreline of the castor or wheel axle and the centreline of the castor wheel or drive wheel width, with the non-sprung castor or wheel being positioned with the centreline of the castor wheel axle nearer to the centre plane of the truck;
35、2) for the non-articulated drive wheel, point M shall be the vertical projection onto the tilt table of the point of intersection between the centreline of the drive wheel axle and the centre line of the drive wheel width. f) For trucks with a sprung castor or wheel point: point M shall be the verti
36、cal projection onto the tilt table of the point of intersection between the centre line of the drive wheel axle and the centre line of the drive wheel width. As shown in Table 1, point N is defined as the centre point of the area of contact between the tilt table surface and the front load wheel clo
37、sest to the tilt axis, XY, of the tilt table. 4.3 Lift height Lift heights for tests shall be measured from the tilt table to the upper-most point of the load-carrying surface. 5 Verification of stability The stability shall be verified in accordance with Table 1.
