AS ISO 22915.21:2021 pdf free download – lndustrial trucks -Verification of stability Part 21: Order-picking trucks with operator position elevating above 1 200 mm.
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 ito entry: This delinition is different from the one given tor normal operating conditions in ISO 22915-1.
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 whit-h 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
d) For trucks with a single or dual non-sprung castor wheel: point M shall be the vertical profection onto the tilt table of the point of intersection between the centreline of the castor wheel axle and the centreline of the castor wheel width.
e) For trucks with non-articulated, non-sprung castors or wheels and a non-articulated drive wheel;
I) for the non-sprung castor or wheel, point M shall be the vertical projection onto the tilt table of the point of intersection between the centreline of the castor or wheel axle and the centreline of the castor or drive wheel width, with the non-sprung castor or wheel being positioned with the centreline of the castor wheel axle nearer to the centre plane of the truck;
for the non-articulated drive wheel, point M shall be the vertical pro)ectIon onto thi tilt table of the point ol intersection between the centreline of the drive wheel axle and the centre line of the drive wheel width.
1) For trucks with a sprung castor or wheel: point M shall be the vertical projection onto the tilt table of the point of intersection between the centreline of the drive wheel axle and the centreline of the drive wheel width.
As shown in Table I point N is defined as the centre point of the area of contact between the tilt table surface and the front load wheel closest to the tilt axis, X—Y, of the tilt table.
4.3 Lift height
Lilt heights for tests shall be measured from the tilt table to the upper-most point of the load carrying surface.
5 Verification of stability
The stability shall be verified in accordance with Table 1.
