AS ISO 22915.11:2015 – lndustrial trucks-Verification of stability Part 11: Industrial variable-reach trucks.
This part of ISO 22915 specafies tests for verifying the stability of Industrial variable-reach trucks, equipped either with fork arms or with load-handling attachments.
It is not applicable to those trucks designed for handling freight containers: nor is it applicable to rough-terrain variable-reach trucks. which are covered by ISO 22915-14.

3 Terms and definItions
For the purposes of this document, the terms and definitions given In ISO 3691-2 and ISO 22915-1 and the following apply.
variable-reach truck
counterbalanced lift truck with an articuLating boom, telescopic or not, non-stewing as defined in ISO 5053 or having a slewing movement of not more than 5 on either side of the trucks longitudinal axis, used for stacking loads
NOTE 1 The load-handhng means may be mounted ec1ly on the llhw means or on an ausillary mast fixed at the end of the lilting means
NOTE 2 Variable-reach trucks may be tilted with a rigid or articulating chassis, slabdizers, axle-locking or lateral frame levelling devices as defined in ISO 3691-2, or two- or I ot,%-wheel steering or articulatrig chassis steering systems.
industrial variable—reach truck
variable-reach truck designed for operation on substantially firm, smooth, level, prepared and consolidated surfaces
C) For trucks with axle locking: pomt 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 titled rearward, shall be positioned
300 mm above the tilt table for trucks of lOt 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 stabilizer&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.
