Agricultural machinery - Safety - Part 20: Grape, olives and coffee harvesters (ISO 4254-20:2025)

This document, when used together with ISO 4254-1:2013 and ISO 4254-1:2013/AMD1:2021, specifies the safety requirements and their verification for the design and construction of trailed and self-propelled harvesters for grapes, olives and coffee. It describes methods for the elimination or reduction of hazards arising from the intended use of these machines by one person (the operator) in the course of normal operation and service. In addition, it specifies the type of information on safe working practices to be provided by the manufacturer.
When provisions of this document are different from those which are stated in ISO 4254-1:2013 and ISO 4254-1:2013/AMD1:2021, the provisions of this document take precedence over the provisions of ISO 4254-1:2013 and ISO 4254-1:2013/AMD1:2021 for machines that have been designed and built according to the provisions of this document.
This document, taken together with ISO 4254-1:2013 and ISO 4254-1:2013/AMD1:2021, deals with all the significant hazards, hazardous situations and events relevant to trailed and self-propelled harvesters for grapes, olives and coffee, when they are used as intended and under the conditions of misuse that are reasonably foreseeable by the manufacturer. It is not applicable to hazards arising from the presence of persons other than the operator, hazards related to lack of visibility, except lighting, hazards related to vibrations and moving parts for power transmission, except for strength requirements for guards and barriers.
This document does not deal with environmental hazards, except noise.
In respect of steering of self-propelled machines, it is applicable only to the ergonomic aspects (for example, location of the steering wheel); no other aspects related to steering are covered.
NOTE            Specific requirements related to road traffic regulations are not taken into account in this document.
This document is not applicable to machines manufactured before the date of its publication.

Landmaschinen - Sicherheit - Teil 20: Trauben-, Oliven- und Kaffee-Erntemaschinen (ISO 4254-20:2025)

Dieses Dokument legt in Verbindung mit ISO 4254 1:2013 und ISO 4254 1:2013/AMD1:2021 die Sicherheitsanforderungen und deren Verifizierung für die Konstruktion und den Bau von gezogenen und selbstfahrenden Erntemaschinen für Trauben, Oliven und Kaffee fest. Es beschreibt Verfahren zur Beseitigung oder Reduzierung von Gefährdungen, die sich aus der bestimmungsgemäßen Verwendung dieser Maschinen durch eine Person (den Bediener) bei normalem Betrieb und üblicher Handhabung ergeben. Zusätzlich legt dieses Dokument die Informationen über sicheres Arbeiten fest, die vom Hersteller zur Verfügung zu stellen sind.
Unterscheiden sich Bestimmungen aus diesem Dokument von denen, die in ISO 4254 1:2013 und ISO 4254 1:2013/AMD1:2021 angegeben sind, haben die Bestimmungen dieses Dokuments für Maschinen, die nach den Festlegungen aus diesem Dokument ausgelegt und gebaut worden sind, Vorrang vor den Anforderungen von ISO 4254 1:2013 und ISO 4254 1:2013/AMD1:2021.
Dieses Dokument behandelt gemeinsam mit ISO 4254 1:2013 und ISO 4254 1:2013/AMD1:2021 alle signifikanten Gefährdungen, Gefährdungssituationen und Gefährdungsereignisse von gezogenen und selbstfahrenden Erntemaschinen für Trauben, Oliven und Kaffee, wenn sie wie beabsichtigt und unter den Bedingungen der vom Hersteller vernünftigerweise vorhersehbaren Fehlanwendung verwendet werden. Es ist nicht anwendbar für Gefährdungen, die sich aus der Anwesenheit von anderen Personen als dem Bediener ergeben, für Gefährdungen durch mangelnde Sicht, mit Ausnahme von Beleuchtung, sowie für Gefährdungen durch Vibrationen in Verbindung mit beweglichen Teilen des Antriebs, mit Ausnahme von Festigkeitsanforderungen an trennende Schutzeinrichtungen und Barrieren.
Dieses Dokument behandelt keine Umweltgefährdungen, mit Ausnahme von Geräuschen.
In Bezug auf die Lenkung von selbstfahrenden Maschinen ist dies lediglich für die ergonomischen Aspekte (z. B. die Position des Lenkrads) anwendbar; andere Aspekte im Zusammenhang mit der Lenkung werden nicht behandelt.
ANMERKUNG   Spezifische Anforderungen im Zusammenhang mit der Straßenverkehrsordnung werden in diesem Dokument nicht berücksichtigt.
Dieses Dokument ist nicht für Maschinen anwendbar, die vor dem Veröffentlichungsdatum dieses Dokuments hergestellt wurden.

En outre, il spécifie le type d'informations que le fabricant doit fournir sur les pratiques d'utilisation sûre.
Lorsque les dispositions du présent document diffèrent de celles indiquées dans l'ISO 4254-1:2013 et l'ISO 4254-1:2013/AMD1:2021, les dispositions du présent document prévalent sur celles de l'ISO 4254-1:2013 et de l'ISO 4254-1:2013/AMD1:2021 pour les machines conçues et construites conformément aux dispositions du présent document.
Le présent document, pris conjointement avec l'ISO 4254-1:2013 et l'ISO 4254-1:2013/AMD1:2021, traite de l'ensemble des phénomènes dangereux, situations et événements dangereux significatifs relatifs aux machines traînées et automotrices utilisées pour vendanger, de récolte des olives et du café, lorsqu'elles sont utilisées conformément à l'usage prévu et dans les conditions de mauvaise utilisation raisonnablement prévisibles par le fabricant. Il n'est applicable ni aux dangers engendrés par la présence de personnes autres que l'opérateur, ni aux phénomènes dangereux associés au manque de visibilité à l'exception de l'éclairage, aux phénomènes dangereux associés aux vibrations et aux éléments mobiles de transmission de puissance, exception faite des exigences de résistance des protecteurs et des barres d'éloignement.
Le présent document ne traite pas des phénomènes dangereux liés à l'environnement, à l'exception du bruit.
En ce qui concerne la direction des machines automotrices, seuls les aspects ergonomiques (par exemple, emplacement du volant) sont couverts; tous les autres aspects relatifs au freinage et à la direction ne sont pas traités.
NOTE            Les exigences techniques spécifiques aux réglementations de la circulation routière ne sont pas prises en compte dans le présent document.
Le présent document n'est pas applicable aux machines fabriquées avant la date de sa publication.
