4.2.2 Stabilizerslaxle locking
Stabilizers or axle locking. if fitted, shall only be used for Tests 1 and 3.
4.2.3 Tests I and 2
The truck shall be positioned on the tilt table so that its load axle. C—C, is parallel to the tilt axis, X—t, in table. See Table 1.
4.2.4 Tests 3, 4 and 5
The truck shall be positioned on the tilt table in a turning position with line M—N parallel to the tilt axis X—Y of the tilt table. See Table 1.
As shown in Table 1, the steered wheel nearest to the tilt axis shal be parallel to X—Y. Port Ms defined as follows.
a) For trucks with an articulating steer axle, point M shall be the projection on the tilt table of the intersection of the longitudinal centre plane. A—A. of the truck with the axis of this axle (see Table 1).
b) For trucks with an articulating chassis, point M shall be the projection on the tilt table of the intersection of the longitudinal centre plane, J—J. of the rear chassts module and the axis of the rear axle when fully articulated see Table 1).
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 the stabilizer pad, if fitted) nearest to the tilt axis, X—Y, of the tilt table.
4.3 Datum point positions
Test 1 shall be conducted with the horizontal position of the load datum point. E, unchanged when elevated from Its lowered position as shown In Figure 2.
With the prescribed test load, set the mast vertical and then elevate to approximately 500 mm above the tilt table. With the shank of the front face of the fork arm set vertical, establIsh poInt E. as shown In FIgure 2 a). on the fork arms or fork carrier having a fixed relationship to the centre of gravity of the test load. E shall be used to provide a reference datum point, F. on the tilt table.
Stabilizers or axle locking. if fitted, shall only be used for Tests 1 and 3.
