The work of preparing Internatio
11、nal 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 committee. International organizations, governmental and non-governmental, in liaison with ISO
12、, 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 accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical com
13、mittees 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 requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the
14、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 22915-2 was prepared by Technical Committee ISO/TC 110, Industrial trucks, Subcommittee SC 2, Safety of powered industrial
15、trucks. This first edition of ISO 22915-2 cancels and replaces ISO 1074:1991, of which it constitutes a technical revision. ISO 22915 consists of the following parts, under the general title Industrial trucks Verification of stability: Part 1: General Part 2: Counterbalanced trucks with mast Part 3:

See Table 1. 4.2.3 Tests 3 and 4 The truck shall be positioned on the tilt table in a turning position with the line, MN, parallel to the tilt axis, XY, of the tilt table. As shown in Table 1, the steered wheel nearest to the til

Point M is defined as follows. a) For trucks having an articulating steer axle: point M shall be the projection on the tilt table of the intersection of the longitudinal centre-plane, AA, of the truck with the axis of this axle. b) For trucks steered by a single wheel
27、: point M shall be the centre point of the tread contact area between the steered wheel and the tilt table surface. c) For trucks steered by twin wheels: point M shall be the centre point of the tread contact area between the steered wheel closest to the tilt axis, XY, of the tilt table and the tilt
28、-table surface. d) For trucks having wheels for steering not connected by a common axle, but that are arranged to articulate approximately about the longitudinal centre-plane of the truck: point M shall be the projection on the tilt table of the intersection of the longitudinal centre-plane of the t
29、ruck, AA, with the steer axle BB connecting the vertical turning axis of the steer wheels. 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 nearest to the tilt axis.

With the shank of the front face of the fork arm set vertical, establish point E, as shown in Figure 2 a), on the fork arms or fork carrier having a fixed relationship to the centre of gravity of the test load. E shall be used to provide a reference datum point, F
