AS ISO 22915.22:2015 pdf download – Industrial trucks – Verification of stability
1 Scope
This part of ISO 22915 specifies the tests to verify the stability of lateral- and front-stacking trucks, as defined in ISO 5053-1, with and without elevating operator position. It applies to trucks fitted with fork arms, shuttle forks, and/or integrated attachments under normal operating conditions.
It applies to trucks ftted with a load carrier that can be shifted laterally or pivoted out of the longitudinal centre plane of the truck. .

3 Terms and definitions
For the purpose of this document, the terms and definitions given in ISO 22915-1 and the fllowing apply
3.1 normal operating condition
operating condition corresponding to the truck travelling indoors on smooth, level floors of sufficient strength such as those of concrete
guided steering steering mode, either mechanical (e.g. guidance rails) or non-mechanical (e.g. inductive guidance, laser sensor or infrared) not controlled directly by the operator, used to steer the truck on a predetermined straight path while travelling restricted steering operation under which the truck’s steering is controlled by the operator and the steering angle is limited to not more than +10° from the forward or reverse travel direction
3.4. unrestricted steering
steering mode controlled by the operator with no limitation of the steering angle
4.2.2 Tests 1, 2 and 3
The truck shall be positioned on the tilt table with the drive (steer) axle B-B and the load axle C-C parallel to the tilt axis X-Y, of the tilt table. See Table 1.
4.2.3 Test 4
The truck shall be positioned on the tilt table with the longitudinal centre plane of truck A-A parallel to the tilt axis X-Y, of the tilt table. See Table 1. 4.2.4 Tests 5, 6 and 7 The truck shall be positioned on the tilt table with the line M-N parallel to the tilt axis X-Y, of the tilt table. Point M is defined as follows:
a) For trucks with dual drive (steer) wheels, point M is the vertical projection onto the tilt table of the point of intersection between the centre line of the drive axle and the centre plane of A-A of the truck.
b) For trucks with a single drive (steer) wheel, point M is the vertical projection onto the tilt table of the point of intersection between the centre line of the drive (steer) axle and the centre line of the drive wheel width.
c)For trucks with a sprung castor or wheel, point M is the vertical projection onto the tilt table of the point of intersection between the centre line of the drive wheel axle and the centre line of drive wheel width.
d) For trucks with a drive (steer axle in an articulated frame), point M is the vertical projection onto the tilt table of the point of intersection between the lateral axis of the articulating frame and the point of articulation.
