Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out through
ISO technical committees. Each member body interested in a subject for which a technical committee
has been established has the right to be represented on that committee. International organizations,
governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely
with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are described
in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the different types
of ISO document should be noted. This document was drafted in accordance with the editorial rules of the
ISO/IEC Directives, Part 2 (see www.iso.org/directives).

Part 3:
Accessories and components
1 Scope
This document establishes the vocabulary of accessories and components of industrial trucks (hereafter
referred to as trucks) as defined in ISO 5053-1.
For the purposes of this document, the terms accessories and components are describing parts and
assemblies which are, or can be, fitted to a truck.
Accessories and components of typical trucks are given in Annex A.
Due to the variance of the individual truck types and the ongoing development of new combinations, it is
not possible to include all the different variations of accessories and components. Therefore, this document
defines, shows and/or describes the typical variances.
2 Normative references

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.
Pour une explication de la nature volontaire des normes, la signification des termes et expressions
spécifiques de l'ISO liés à l'évaluation de la conformité, ou pour toute information au sujet de l'adhésion de
l'ISO aux principes de l’Organisation mondiale du commerce (OMC) concernant les obstacles techniques au
commerce (OTC), voir www.iso.org/avant-propos.
Le présent document a été élaboré par le comité technique ISO/TC 110, Chariots de manutention, sous-comité
SC 1, Terminologie générale.
En complément du texte rédigé dans les langues officielles de l'ISO (anglais, français), le présent document
contient du texte en allemand. Ce texte est publié sous la responsabilité du Comité membre de l’Allemagne

Partie 3:
Composants et équipements
1 Domaine d'application
Le présent document établit le vocabulaire des composants et équipements des chariots de manutention (ci-
après dénommés chariots) tels que définis dans l’ISO 5053-1.
Pour les besoins du présent document, les termes composants et équipements décrivent des parties et des
ensembles qui sont ou peuvent être montés sur un chariot.
Les composants et équipements des chariots types sont indiqués à l’Annexe A.
En raison des différences entre les types de chariots particuliers et du développement actuel de nouvelles
combinaisons, il n’est pas possible d’inclure toutes les variantes de types de composants et d’équipements.
Par conséquent, le présent document définit, illustre et/ou décrit les variantes types.
2 Références normatives
Le présent document ne contient aucune référence normative.
