Industrial trucks — Verification of stability — Part 10: Additional stability test for trucks operating in the special condition of stacking with load laterally displaced by powered devices

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.
