4 Test conditions
4.1 General
See Iso 22915-1.
4.2 Position of truck on the tilt table
4.2.1 Load and steer axles
The load/drive axle and the steer axle are defined by Figure 1.
4.2.2 Tests 1 and 2
The truck shall be positioned on the tilt table so that its load axle, C—C, and steer axle, B—B, are parallel to the
tilt axis. X—Y, of the tilt table. See Table 1.
4.2.3 Tests 3, 4 and 5
The truck shall be positioned on the tilt table in a turning position with the line, M—N, parallel to the tilt axis, X—Y, of the tilt table. See Table 1.
For trucks with an articulating steer axle, the wheel on the steer axle nearest to the tilt axis, X—Y, shall be parallel to X—Y. See Table 1.
Point M is defined as follows:
a) For trucks with an articulating steer axle: point M shall be the projection onto the tilt table of the intersection of the longitudinal centre plane, A—A, of the truck with the axis of the steer axle (see Table 1).
b) For trucks with an articulating chassis: point M shall be the projection onto the tilt table of the intersection of the longitudinal centre plane. J—J, of the rear chassis module and the axis of the rear axle (see Table 1) when fully articulated.
C) For trucks with axle locking: point M shall be the centre point of the area of contact between the tilt table and the rear wheel nearest to the tilt axis, X—Y, of the tilt table (see Table 1).
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 load wheel (or stabilizer pad, if fitted) closest to the tilt axis, X—Y, of the tilt table.
4.3 Test load
Tests 1 and 3 shall be conducted with the test load in the least stable combination of lift and reach, with the fork arms in the horizontal position.
Test 5 shall be conducted at maximum and minimum boom extensions, at the maximum boom angle and with the fork arms in the horizontal position.
See Table 1.
4.4 Lift height
For tests simulating travel, i.e. Tests 2 and 4, the upper face of the fork arms, measured at the heel of the fork arm when fully tilted rearward, shall be positioned
— 300 mm above the tilt table for trucks of 10 t rated capacity or less, and 500 mm for trucks of greater than 10 t rated capacity.
See Table 1.
4.5 Lateral test procedure
For trucks fitted with selectable stabilizers and/or axle locking, Tests 1 and 3 shall be conducted both with stabilizers/axle locking engaged and disengaged.
See Table 1.
5 Verification of stability
The stability of a truck shall be verified in accordance with Table 1.
6 Marking
The capacity under the operating condition, with stabilizers and/or axle locking engaged and disengaged. as determined by this stability test, shall be indicated on an information plate in view of the operator in the normal operating position according to ISO 3691-2.AS ISO 22915.11 pdf download.
