AS ISO 22915.21:2015 pdf download – Industrial trucks—Verification of stability Part 21: Order-picking trucks with operator position elevating above 1 200 mm.
1 Scope This part of ISO 22915 specifies the tests for verifying the stability of order-picking trucks with an elevating operator position, as defined in ISO 5053, where the operator’s position can be raised to an elevation above 1 200 mm. It is applicable to industrial trucks fitted with fork arms, platforms and/or integrated attachments under normal operating conditions. It is not applicable to trucks fitted with a load carrier that can be shifted laterally or pivoted out of the truck’s longitudinal centre plane. 2 Normative references The following referenced documents are indispensable for the application of this document.

4.2.2 Test 1 The truck shall be positioned on the tilt table so that its drive/steer axle, B–B, and load axle, C–C, are parallel to the tilt axis, X–Y, of the tilt table. See Table 1. 4.2.3 Tests 2, 3, 4 and 5 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. See Table 1. Point M is defined as follows. a) For trucks with a single drive (steer) wheel: point M shall be the vertical projection onto the tilt table of the point of intersection between the centreline of the drive/steer axle and the centreline of the drive wheel width. b) For trucks with a drive/steer axle in an articulating frame articulated in the centre plane of the truck: point M shall be the vertical projection onto the tilt table of the point of intersection between the lateral axis of the articulating frame and the centre plane, A–A, of the truck.
