This document specifies an additional test for verifying the stability of a laden truck fitted with a powered load-handling device, such as a sideshift, which can displace the centre of gravity laterally to a substantial, predetermined extent from the longitudinal centre plane of the truck or from the centred position. Such devices are used in this mode for depositing and retrieving a load.

A displacement is considered to be a substantial displacement if it is more than:
— 100 mm, for a truck with a rated capacity < 5 000 kg;
— 150 mm, for a truck with a rated capacity ≥ 5 000 kg and ≤ 10 000 kg;
— 250 mm, for a truck with a rated capacity > 10 000 kg and < 20 000 kg;
— 350 mm, for a truck with a rated capacity ≥ 20 000 kg;

This document is applicable to the following types of trucks as defined in ISO 5053-1:
a) counterbalance trucks;
b) reach and straddle trucks;
c) pallet stackers;
d) bidirectional and multidirectional trucks;
e) industrial variable-reach trucks;
f) rough-terrain trucks with mast;
g) rough-terrain variable reach trucks;
h) counterbalance trucks with articulated steering;
i) variable-reach container handler;
j) counterbalanced container handler.
