3Terms and definitions
For the purposes of this document, the terms and definitions given in ISO 3691-2 and IS0 22915-1 and thefollowing apply.
counterbalanced lift truck with an articulating boom, telescopic or not, non-slewing as defined in IlSO 5053 orhaving a slewing movement of not more than 5° on either side of the truck’s longitudinal axis,used forstacking loads
NOTE1 The load-handling means may be mounted directly on the liting means or on an auxiliary mast fixed at theend of the lifting means.
NOTE2 Variable-reach trucks may be fitted with a rigid or articulating chassis, stabilizers, axle-locking or lateral framelevelling devices as defined in ISO 3691-2, or two- or four-wheel steering or articulating chassis steering systems.
industrial variable-reach truck
variable-reach truck designed for operation on substantially firm, smooth, level, prepared and consolidatedsurfaces
4 Test conditions
See ISO 2291 5-1 .
4.2 Position of truck on the tilt table
4.2.1 Load and steer axles
The load/drive axle and the steer axle are defined by Figure 1 .
4.2.2Tests 1 and 2
The truck shall be positioned on the tilt table so that its load axle, C-C, and steer axle,B-B, are parallel to thetilt axis,x-Y, of the tilt table.See Table 1.
4.2.3 Tests 3,4 and 5
The truck shall be positioned on the tlt 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 beparallel 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 tlt 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 tlt table of the intersection of the longitudinal centre plane,J-J, of the rear chassis’ module and the axis of the rear axle (seeTable 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, 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 tilted rearward, shall be positioned
