Agricultural machinery - Safety - Part 18: Loader wagons and forage transport wagons (ISO/DIS 4254-18:2019)

This part of ISO 4254, intended to be used together with ISO 4254-1, specifies the safety requirements
and their verification for the design and construction of trailed loader wagons and forage transport
wagons and silage and forage body works for carrier vehicles, where the discharge is done at the rear
of the machine and which is intended for the use by only one person (operator). In addition, it specifies
the type of information on safe working practices including residual risks to be provided by the
manufacturer.

Landmaschinen - Sicherheit - Teil 18: Ladewagen und Häckseltransportwagen (ISO/DIS 4254-18:2019)

Dieses Dokument, das zusammen mit ISO 4254 1 anzuwenden ist, legt die Sicherheitsanforderungen und ihre Verifizierung für die Gestaltung und Konstruktion von
- gezogenen Ladewagen,
- gezogenen Häckseltransportwagen,
- Silage- und Häckselaufbau zur Montage an einem Trägerfahrzeug,
- Anhängern mit Abschiebeeinrichtung, Leisten oder Schubboden,
für den Gebrauch durch nur eine Person (Bediener) fest. Zusätzlich legt das Dokument fest, welche Informationen zum sicheren Betrieb (einschließlich Restgefahren) vom Hersteller zur Verfügung zu stellen sind.
Dieses Dokument ist nicht anwendbar auf:
- selbstfahrende Ladewagen und selbstfahrende Häckseltransportwagen,
- Anhänger mit Kippaufbau, im Gleichgewicht gehalten oder aufgesattelt für die Anwendung in der Landwirtschaft.
Wenn Anforderungen dieses Dokuments von den Anforderungen in ISO 4254 1 abweichen, haben die Anforderungen dieser Norm Vorrang gegenüber den Anforderungen von ISO 4254 1 für Maschinen, die nach den Bestimmungen dieser Norm konzipiert und gebaut worden sind.
Dieses Dokument behandelt gemeinsam mit ISO 4254 1 alle signifikanten Gefährdungen, Gefährdungssituationen und Gefährdungsereignisse von Ladewagen und Häckseltransportwagen, wenn sie wie beabsichtigt und unter den Bedingungen der vom Hersteller vernünftigerweise vorhersehbaren Fehlanwendung verwendet werden (siehe Anhang A). Es gilt nicht für Gefährdungen durch die Anwesenheit anderer Personen als dem Bediener und Gefährdungen in Verbindung mit beweglichen Teilen des Antriebs, mit Ausnahme von Festigkeitsanforderungen an trennende Schutzeinrichtungen und Barrieren.
Dieses Dokument gilt nicht für Ladewagen und Häckseltransportwagen, die vor dem Datum der Veröffentlichung dieses Dokuments hergestellt wurden.

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 documents 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).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www .iso .org/ patents).
