AS ISO 22915.22:2015 Industrial trucks—Verification of stability
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 Tests5, 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.
e) For trucks with a non-articulated drive 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 centre line of drive wheel width.
f) For trucks with non-articulated, non-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 castor or wheel axle and the centre line of the castor wheel or drive wheel width. The castor or wheel shall be positioned with the centre line of the castor wheel axle nearer to the centre plane of the truck.
g) For trucks with five-wheel suspension, four solid and one articulated point M are the projection to the tilt table of the intersection of the pivot axis of the three-wheel articulated frame and the centre line between the tires.
h) For trucks with centre-articulating frame steering, point M is the projection to the tilt table from the intersection of the centre line of the drive wheel axle and the centre line of the drive wheel width.
Point N indicates 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.
