AS ISO 22915.14:2015 pdf download – Industrial trucks – Verification of stability
1 Scope
This part of ISO 2291 5 specifies tests for verifying the stability of rough-terrain variable-reach trucks, equipped with fork arms or with load carrying or non-load carrying attachments. It is not applicable to those trucks designed for handling freight containers or for lifting people or suspended loads.

ISO 2291 5-1 , Industrial trucks — Verification of stability — Part 1: General
3 Terms and definitions
For the purposes of this document, the terms and definitions given in ISO 2291 5-1 apply.
4 Test conditions
4.1 General
See ISO 2291 5-1 .
4.2 Position of truck on the tilt table
4.2.1 Load and steer axles
The load axle and the steer axle are defined by Figure 1 .
4.2.2 Tests 1 and 2
The truck shall be positioned on the tilt table so that its load axle, C–C, is parallel to the tilt axis, X–Y, of the tilt
table. See Table 1 .
4.2.3 Tests 3, 4 and 5
The truck shall be positioned on the tilt table in a turning position with the line, M–N, parallel to the tilt axis,X–Y, of the tilt table. See Table 1 .
For trucks with an articulating steer axle, the wheel on the steer axle nearest to the tilt axis, X–Y, shall be parallel to X–Y. See Table 1 .
Point M is defined as follows:
a) For trucks with an articulating steer axle: point M shall be the projection onto the tilt table of the intersection of the longitudinal centre plane, A–A, of the truck with the axis of the steer axle (see Table 1 ).
b) For trucks with an articulating chassis: point M shall be the projection onto the tilt table of the intersection of the longitudinal centre plane, J–J, of the rear chassis module and the axis of the rear axle (see Table 1 ) when fully articulated.
c) For trucks with axle locking: point M shall be the centre point of the area of contact between the tilt table and the rear wheel nearest to the tilt axis of the tilt table (see Table 1 ).
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 (or stabilizer pad, if fitted) closest to the tilt axis, X–Y, of the tilt table.
4.3 Test load
Tests 1 and 3 shall be conducted with the test load in the least stable combination of lift and reach, with the fork arms parallel with the tilt table, and this shall remain unchanged during the tests.
The centre of gravity of the test load shall be positioned, according to ISO 2291 5-1 , on the longitudinal centre plane of the truck, except where a lateral slope correction device is used, which is the case for Test 3. See Table 1 .
