AS ISO 22915.21:2021 pdf download.Industrial trucks — Verification of stability
1 Scope
This document specifies the tests for verifying the stability of order picking trucks with an elevating operator position, as defined in ISO 5053-1, where the operator’s position can be raised to an elevation above 1 200 mm.
It is applicable to industrial trucks fitted with fork arms, platforms and/or integrated attachments under normal operating conditions.
It is not applicable to trucks fitted with a load carrier that can be shifted laterally or pivoted out of the truck’s longitudinal centre plane.

3.1 normal operating conditions
operating conditions corresponding to the truck travelling indoors on smooth, level floors of sufficient strength such as those of concrete
Note 1 to entry: This definition is different from the one given for normal operating conditions in ISO 22915-1.
3.2 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
3.3 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 Test conditions
4.1 General
See ISO 22915-1.
4.2 Position of the truck on the tilt table
4.2.1 Load and drive/steer axles
The load axle and the drive/steer axle are defined by Figure 1.
4.2.2 Tests 1
The truck shall be positioned on the tilt table so that its drive/steer axle, B–B, and load axle, C–C, are parallel to the tilt axis, X–Y, of the tilt table. See Table 1.
4.2.3 Tests 2, 3, 4 and 5
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. See Table 1.
