AS 22915.9:2018 Industrial trucks—Verifcation of stability
5.6.1  Lift height for tests simulating stacking
Test 1 (see Table 1) shall be conducted with the horizontal position of the load datum point (e.g. point E) unchanged when elevated from its lowered position [see Figure 3 a), b) and c)].
With the prescribed test load, set the mast vertical and perpendicular to the tilt table and then elevate to approximately 300 mm. Using the shank of the front face of the fork arm or load-engaging means, establish a point E [see Figure 3 a)], on the fork arms or load-engaging means having a fixed relationship to the centre of gravity of the test load. This point E shall be used to provide a reference datum F on the tilt table. When the mast is elevated, a new point F1 on the tilt table may occur [see Figure 3 b)]. By the following adjustments, this new point F1 can be returned to the original location of F [see Figure 3 c)].
Changes in the location of F1 shall be corrected by varying the tilt of the mast within the limits provided by the design of the truck.
5.6.2  Lift height for tests simulating travelling with the container
For tests simulating travelling with a container, the centre of gravity of the test load shall be positioned 2 350 mm above the seat index point (SIP) as defined in ISO 5353.
NOTE  This lift height does not apply where it is not necessary to elevate the container to obtain adequate visibility in the direction of travel, e.g. high-level operator position or driving in reverse (container trailing). In these circumstances, the load can be positioned in the actual position defined by the manufacturer.
5.6.3  Lift height for tests simulating travelling without the container
For tests simulating travelling without a container, the upper face of the fork arms, measured at the heel of the fork arm, shall be positioned 300 mm above the tilt table for trucks with a rated capacity less than or equal to 10 t and 500 mm for trucks with a rated capacity of greater than 10 t.Load handling means other than forks shall be positioned in a way that the bottom surface of the load handling means is positioned 900 mm above the seat index point (SIP) as defined in ISO 5353.
NOTE  This lift height does not apply where it is not necessary to elevate the load handling means to obtain adequate visibility in the direction of travel, e.g. high-level operator position. In these circumstances, the load handling means can be positioned in the actual position defined by the manufacturer.
