10、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
11、 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.The procedures used to develop thi
12、s document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Di
13、rectives, Part 2 (see www.iso.org/directives).Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights.

22、7:2016Industrial trucks Verification of stability Part 7: Bidirectional and multidirectional trucks1 ScopeThis part of ISO 22915 specifies the tests for verifying the stability of bidirectional and multidirectional trucks with tilting or non-tilting mast or fork arms.It is also applicable to trucks
23、operating under the same conditions when equipped with load-handling attachments.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

27、tioned on the tilt table so that its drive/steer axle, BB, and outrigger (load/steer) axle, CC, are parallel to the tilt axis, XY, of the tilt table. See Table 1.4.2.3 Tests 6 to 9The truck shall be positioned on the tilt table with the line, MN, or the outrigger (load/steer) axle, CC, parallel to t
28、he tilt axis, XY, of the tilt table. See Table 1.Point M is defined as follows.a) For trucks with a sprung castor wheel: point M shall be the vertical projection onto the tilt table of the point of intersection between the centreline of the drive/steer axle and the centreline of the drive wheel widt
29、h.b) For trucks with drive/steer wheels in an articulated frame: point M shall be the vertical projection onto the tilt table of the point of intersection between the articulated frame axle and the lateral axis of the articulated frame.c) For trucks with a single drive/steer wheel: point M shall be
30、the vertical projection onto the tilt table of the point of intersection between the centreline of the drive/steer axle and the centreline 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 load wheel nea
31、rest to the tilt axis, XY, of the tilt table.4.3 Datum point positions4.3.1 GeneralTest 1 may be conducted with the horizontal position of the load datum point, E, unchanged when elevated from its lowered position as shown in Figure 2.With the prescribed test load, set the mast vertical and then ele
32、vate to approximately 300 mm above the tilt table. With the shank of the front face of the fork arm set vertical, establish point E, as shown in Figure 2 a) and b), on the fork arms or fork carrier having a fixed relationship to the centre of gravity of 2 ISO 2016 All rights reservedBS ISO 22915-7:2
33、016ISO 22915-7:2016(E)the test load. Point E shall be used to provide a reference datum point, F, on the tilt table. When the mast is elevated, a new point, F1, on the tilt table might occur, as shown in Figure 2 c) and d). This new point may be returned to the original location of F, as shown in Fi
34、gure 2 e) and f).For trucks with tilting masts, changes in the location of F1 may be corrected by varying the tilt of the mast within the limits provided by the design of the truck. See Figure 2 a), c) and e).For trucks with non-tilting masts, the location of F1is subject to regional requirements (s
35、ee 4.3.2).4.3.2 Regional requirements for trucks with non-tilting masts4.3.2.1 North AmericaThe location of F1shall not be corrected. Only correction by varying the mast tilt is permissible.4.3.2.2 All other regionsAdjustments in the fork arms or fork carrier tilt, fork carrier retraction (where pro
36、vided) or retraction of the mast may be used to correct for changes in the location of point F1, within the limits provided by the design of the truck. See Figure 2 b), d) and f).4.4 Lift height for tests simulating travelFor tests simulating travel (Tests 5, 6 and 7), the upper face of the fork arm
37、s, measured at the heel of the fork arm, shall be positioned 300 mm above the tilt table for trucks with a rated capacity less than or equal to 10 t, and 500 mm for trucks with a rated capacity of greater than 10 t.
