BS ISO 22915-8:2018 pdf download – Industrial trucks — Verification of stability Part 8: Additional stability test for trucks operating in the special condition of stacking with mast tilted forward and load elevated
The ISO 22915 series deals with the safety of industrial trucks, as defined in ISO 5053‑1, relative to their stability and the verification of that stability. For the purposes of the ISO 22915 series, 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 document specifies an additional test for verifying the stability of a truck stacking with mast tilted forward and load in the elevated position. It is applicable to the following types of truck:
a) counterbalanced trucks with tiltable masts, as specified in ISO 22915‑2;
b) reach (retractable mast or forks) and straddle trucks with tiltable masts, as specified in ISO 22915‑3;
c) pallet stackers with tiltable masts, as specified in ISO 22915‑4;
d) bidirectional and multidirectional (retractable mast or forks) trucks with tiltable masts, as specified in ISO 22915‑7;
e) rough-terrain trucks with tiltable masts, as specified in ISO 22915‑13;
f) counterbalanced trucks fitted with articulated steering with tiltable masts, as specified in ISO 22915‑15.

4.2.3 Bidirectional and multidirectional trucks
The position of the truck on the tilt table shall be in accordance with test 1 of ISO 22915‑7.
4.3 Position of the mast
The test shall be carried out with the mast and forks fully elevated and fully titled forward.
5 Verification of stability
The stability of the truck with the mast tilted forward and at maximum elevation shall be verified in accordance with test 1 of ISO 22915‑2, ISO 22915‑3, ISO 22915‑4 or ISO 22915‑7 1) depending on the type of truck.
The capacity under this special operating condition, as determined by this additional stability test, and the angle of forward tilt of the mast shall be indicated on an information plate in view of the operator in the normal operating position according to ISO 3691‑1.BS ISO 22915-8 pdf download.
