3 Terms and definitions
For the purposes of this document, the terms and definitions given in ISO 22915-1 apply.
4 Test Conditions
4.1 General
See ISO 22915-1.
4.2 PosEtjon of truck on the tilt table
4.2.1 Load and steer axles
The load 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, is parallel to the tilt axis, X- -Y, of the tilt table. See Table 1.
4.2.3 Tests3, 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 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 ftted) 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 parallel with the tilt table, and this shall remain unchanged during the tests. The centre of gravity of the test load shall be positioned, according to ISO 22915-1, on the longitudinal centre plane of the truck, except where a lateral slope correction device is used, which is the case for Test 3.
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 twcks of 10 1 rated capacity or less, and 500 mm for trucks of greater than 10 t rated capacity. Test 5 shall be conducted at maximum and minimum boom extension, at maximum boom angle and with the fork arms in the horizontal position. See Table 1.
4.5 Lateral test procedure
For trucks fitted with operator-selectable stabilizers and/or manual axle locking, Tests 1 and 3 shall be conducted both with stabilizers/axle locking engaged and disengaged.
For trucks fitted with operator-selectable stabilizers, or chassis levelling, Test 3 shall be performed with a maximum lateral slope correction of 7 % (4°). Lateral slope correction shall only be achieved by either operator-selectable stabilizers or lateral levelling.
For the other tests, the lateral slope correction shall not be used. See Table 1.
5 Verification of stability
The stability of a truck shall be verified in accordance with Table 1.
6 Marking
The additional capacity, as determined by stability tests with stabilizers and or chassis levelling (see 4.5), shall be indicated on the load chart (see Annex A).AS ISO 22915.14 pdf download.
