AS ISO 22915.21:2015 pdf download.lndustrial trucks—Verification of stability Part 21: Order-picking trucks with operator position elevating above 1 200 mm.
C) For trucks with dual drive (steer) wheels: point M shall be the vertical projection onto the tilt table of the point of intersection between the centreline of the drive/steer axle and the centre plane, A—A, of the truck.
d) For trucks with non-articulated, non-sprung castors: point M shall be the vertical projection onto the tilt table of the point of intersection between the centreline of the castor wheel width, with the non-sprung castor positioned with the centreline of the castor wheel axle nearer to the centre plane of the truck.
e) For trucks with non-articulated, non-sprung castors or wheels and a non-articulated drive wheel:
1) 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 wheel 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;
2) for the non-articulated drive 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 centre line of the drive wheel width.
f) For trucks with a sprung castor or wheel point: point M shall be 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 the drive wheel width
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 front load wheel closest to the tilt axis, X—Y, of the tilt table.
4.3 LIft height
Lift 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.
d) For trucks with non-articulated, non-sprung castors: point M shall be the vertical projection onto the tilt table of the point of intersection between the centreline of the castor wheel width, with the non-sprung castor positioned with the centreline of the castor wheel axle nearer to the centre plane of the truck.
e) For trucks with non-articulated, non-sprung castors or wheels and a non-articulated drive wheel:
1) 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 wheel 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;
2) for the non-articulated drive 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 centre line of the drive wheel width.
f) For trucks with a sprung castor or wheel point: point M shall be 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 the drive wheel width
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 front load wheel closest to the tilt axis, X—Y, of the tilt table.
4.3 LIft height
Lift 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.
