4.2.2 Tests 1.2.4 and 7 to 10 for longitudinal direction of test
The truck shall be positioned on the tilt table with the steer axle B—B and the load axle C—C parallel to the tilt axis X—Y o[the tilt table.
4.2.3 Tests 3,5.6 and 7 to 10 for lateral direction of test
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 one or more non-sprung castor wheels, point M is the vertical projection onto the tilt table of the point of intersection between the centreline of the castor wheel axle and the midpoint of the wheel(s), with the non-sprung castor being positioned with the centreline of the castorwheel axle parallel to tilt axis X—Y or at any other orientation that produces minimum stability.
b) For trucks having non articulating dual steer wheels, point M is the vertical projection onto the tilt table of the point of intersection between the centreline of the steer axle and the centreline of the width over both steer wheels, with the axle of the steer wheels positioned parallel to the tilt axis X-Y or at any other orientation that produces minimum stability.
c) For trucks with stabilizers, point M Is the vertical projection onto the tilt table of the point of symmetry of the stabilizer contact surface.
Point N is defined as the centre point of the area of contact between the tilt table surface and the load wheel nearest to the tilt axis X—Y of the tilt table.
5 Verification of stablilty
5.1 DynamIc test — Platform trucks
This dynamic test applies only to platform trucks.
The unladen truck moving at a stabilized speed of 1 rn/s ± 10 % shall be pushed into a vertical obstacle 20mm high with its wheel or both wheels at the same time. The force to push the truck shall cease when the truck hits the obstacle. The force to move the platform shall be applied at the lower platform (see Figure 2). This test shall be carried out in both directions, i.e. pushed and pulled.
