Industrial trucks — Vocabulary — Part 3: Accessories and components
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. In addition to text written in the official ISO languages (English, French), this document gives text in German, Italian and Chinese. This text is published under the responsibility of the member bodies for Germany (DIN), Italy (UNI) and China (SAC), and is given for information only. Only the text given in the official languages can be considered as ISO text.
Chariots de manutention — Vocabulaire — Partie 3: Composants et équipements
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. En complément du texte rédigé dans les langues officielles de l'ISO (anglais, français), le présent document contient du texte en allemand, italien et chinois. Ce texte est publié sous la responsabilité du Comité membre de l’Allemagne (DIN), d'Italie (UNI) et de Chine (SAC), et est donné uniquement pour information. Seul le texte rédigé dans les langues officielles peut être considéré comme étant un texte de l'ISO.

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).
ISO draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed patent
rights in respect thereof. As of the date of publication of this document, ISO had not received notice of (a)
patent(s) which may be required to implement this document. However, implementers are cautioned that
this may not represent the latest information, which may be obtained from the patent database available at
www.iso.org/patents. ISO shall not be held responsible for identifying any or all such patent rights.
Any trade name used in this document is information given for the convenience of users and does not
