23、O 22915-2:2015-11Industrial trucks Verification of stability Part 2: Counterbalanced trucks with mast Introduction An important step forward in work on the ISO 22915 series was the agreement to put in place a new structure. The stability tests are presented in the form of a basic part describing and
24、 defining stability tests in general, together with separate parts that each give specific stability test criteria and requirements for a different truck type. From the very beginning, the task of the Working Group involved was to establish the new structure and revise existing standards to create a
25、 series of International Standards complying with the major legislative regulations in the world such as those in force in the EU, USA, Japan and Australia. For several problem areas compromises were needed and will be needed in the future. In order to ensure that these International Standards are a
26、ctively used in the ISO member countries worldwide, it will be necessary that they replace existing national standards. Only in this way will there will be the guarantee that products in accordance with these International Standards can be shipped worldwide, freely and without any technical barriers
27、 to trade. 5DIN ISO 22915-2:2015-111 Scope This part of ISO 22915 specifies the tests for verifying the stability of counterbalanced trucks with masts, equipped with fork arms or with load handling attachments. It is not applicable to those trucks designed for handling freight containers, dealt with

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
32、Table 1, the steered wheel nearest to the tilt axis shall be parallel to XY. 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
33、axle. b) For trucks steered by a single wheel: 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
34、tilt axis, XY, of the tilt table and the tilt-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 intersect
35、ion of the longitudinal centre-plane of the truck, 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. 7DIN
