ISO 22915-20:2008 Industrial trucks - Verification of stability - Part 20: Additional stability test for trucks operating in the special condition of offset load, offset by utilization
ISO 22915 deals with the safety of industrial trucks, as defined in ISO 5053, relative to their stability and the
verification of that stability. For the purposes of ISO 22915, industrial trucks are wheeled, self-propelled or
pedestrian-propelled vehicles, excepting those running on rails. They are either operator-controlled or
driverless and designed to carry, tow, push, lift, stack or tier in racks.
This part of ISO 22915 specifies an additional test for verifying the stability of a laden truck whose utilization
creates the special operating condition whereby the load centre of gravity is substantially offset from the
truck's longitudinal centre plane. It is applicable to the following types of truck:
a) counterbalanced trucks, as specified in ISO 22915-2;
b) reach (retractable mast or forks) and straddle trucks, as specified in ISO 22915-3;
c) pallet stackers, as specified in ISO 22915-4;
d) bidirectional and multidirectional (retractable mast or forks) trucks, as specified in ISO 22195-7;
e) rough-terrain variable reach trucks 1);
f) counterbalanced trucks fitted with articulated steering 1);
g) variable reach trucks 1);
h) rough-terrain trucks with mast.
A load is considered to be substantially offset if displaced by 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.
