Industrial trucks — Verification of stability — Part 25: Rough-terrain variable-reach trucks operating in the special condition of handling freely suspended loads

This part of ISO 22915 specifies static tests for verifying the stability of rough-terrain variable-reach trucks (hereafter referred to as non-slewing trucks) and slewing rough-terrain variable-reach trucks (hereafter referred to as slewing trucks) as defined in ISO 5053-1, operating in the special condition of handling freely suspended loads. This document covers trucks fitted with a lifting attachment or lifting point when used in the following applications: - picking and placing loads (stationary operation) on substantially firm, smooth, level, and prepared surfaces - travelling with load on unimproved natural terrain and disturbed-terrain with slopes not exceeding limits determined by the manufacturer, at travel speeds not exceeding 1.4 km/h and with boom angle and extension not exceeding manufacturers limits This document does not deal with hazards that could occur due to: - action of the wind; - dynamic motion of the load. Note: A tag line or a tether can be used to restrain the dynamic effects of the load during travel. It is not applicable to those trucks: - designed for handling freight containers; - with an articulating chassis; - equipped with integrated and non-integrated personnel work platforms.

In this document, verification of stability is intended to be the measure of resistance to overturning under
rigidly-controlled static conditions that include considerations for dynamic factors for normal application
and operation of a rough-terrain variable-reach truck operating in the special condition of handling freely
suspended loads. Influencing factors include: mass, mass distribution, travel speed, wind actions, truck
configuration for pick and carry operation, wheelbase, truck suspension, tyre and boom deflection under load.

Avant-propos
L'ISO (Organisation internationale de normalisation) est une fédération mondiale d'organismes nationaux
de normalisation (comités membres de l'ISO). L'élaboration des Normes internationales est en général
confiée aux comités techniques de l'ISO. Chaque comité membre intéressé par une étude a le droit de faire
partie du comité technique créé à cet effet. Les organisations internationales, gouvernementales et non
gouvernementales, en liaison avec l'ISO participent également aux travaux. L'ISO collabore étroitement avec
la Commission électrotechnique internationale (IEC) en ce qui concerne la normalisation électrotechnique.
Les procédures utilisées pour élaborer le présent document et celles destinées à sa mise à jour sont
décrites dans les Directives ISO/IEC, Partie 1. Il convient, en particulier, de prendre note des différents
critères d'approbation requis pour les différents types de documents ISO. Le présent document a
été rédigé conformément aux règles de rédaction données dans les Directives ISO/IEC, Partie 2 (voir
www.iso.org/directives).
L’ISO attire l’attention sur le fait que la mise en application du présent document peut entraîner l’utilisation
d’un ou de plusieurs brevets. L’ISO ne prend pas position quant à la preuve, à la validité et à l’applicabilité de
tout droit de propriété revendiqué à cet égard. À la date de publication du présent document, l’ISO n'avait pas
reçu notification qu’un ou plusieurs brevets pouvaient être nécessaires à sa mise en application. Toutefois,
il y a lieu d’avertir les responsables de la mise en application du présent document que des informations
plus récentes sont susceptibles de figurer dans la base de données de brevets, disponible à l'adresse
www.iso.org/brevets. L’ISO ne saurait être tenue pour responsable de ne pas avoir identifié tout ou partie de
tels droits de propriété.
Les appellations commerciales éventuellement mentionnées dans le présent document sont données pour
information, par souci de commodité, à l’intention des utilisateurs et ne sauraient constituer un engagement.

Introduction
Dans le présent document, la vérification de la stabilité est destinée à être la mesure de la résistance au
renversement dans des conditions statiques strictement contrôlées qui comprennent des considérations pour
