Earth-moving machinery - Safety - Part 8: Requirements for graders
This document, together with part 1, deals with all significant hazards for earth-moving machinery - graders when they are used as intended and under the conditions of misuse which are reasonably foreseeable by the manufacturer associated with the whole life time of the machine (see Clause 4).
The requirements of this part are complementary to the common requirements formulated in
prEN 474-1. This document does not repeat the requirements from prEN 474-1, but adds or replaces the requirements for application for earth moving machinery - graders.
This part also deals with graders equipped with attached snowplough.
This European Standard is not applicable to graders manufactured before the date of publication of this European Standard by CEN.
Erdbaumaschinen - Sicherheit - Teil 8: Anforderungen für Grader
Dieses Dokument behandelt zusammen mit EN 474 1:2022 alle signifikanten Gefährdungen, Gefährdungssituationen und ‑ereignisse von Gradern, wie sie in 3.1 definiert sind, wenn diese Maschinen bestimmungsgemäß verwendet werden sowie unter den vernünftigerweise vom Hersteller vorhersehbaren Fehlanwendungen (siehe Anhang A) für die gesamte Lebensdauer der Maschine wie in EN ISO 12100:2010, 5.4, beschrieben betrieben werden.
Die Anforderungen dieses Dokuments gelten ergänzend zu den allgemeinen Anforderungen in EN 474 1:2022. Dieses Dokument wiederholt nicht die Anforderungen aus EN 474 1:2022, sondern ergänzt oder ändert diese für den Einsatz von Gradern.
Dieses Dokument enthält keine Leistungsanforderungen an Sicherheitsfunktionen von Steuerungssystemen.
Die folgenden signifikanten und relevanten Gefährdungen werden in diesem Dokument nicht behandelt:
— Kraftübertragung zwischen einer selbstfahrenden Maschine (oder einer Zugmaschine) und einer angetriebenen Maschine;
— Laserstrahlung;
— Blitzschlag.
Dieses Dokument ist nicht anwendbar für Grader, die vor der Veröffentlichung dieses Dokuments durch CEN hergestellt wurden.
Engins de terrassement - Sécurité - Partie 8 : Prescriptions applicables aux niveleuses
Le présent document associé à l’EN 474‑1:2022 traite de tous les phénomènes dangereux significatifs, situations dangereuses et événements se rapportant aux niveleuses telles que définies en 3.1, lorsqu'elles sont utilisées normalement et dans les conditions prévues, mais en tenant également compte des mauvais usages raisonnablement prévisibles (voir Annexe A), associés à toute la durée de vie de l'engin, comme décrit dans l'EN ISO 12100:2010, 5.4.
Les prescriptions du présent document viennent en complément des prescriptions communes présentées dans l’EN 474 1:2022. Le présent document ne répète pas les prescriptions de l’EN 474 1:2022, mais complète ou modifie les prescriptions pour les niveleuses.
Le présent document ne spécifie aucune prescription de performance relative aux fonctions de sécurité du (des) système(s) de commande.
Les phénomènes dangereux significatifs et pertinents suivants ne sont pas couverts par le présent document :
— transmission de puissance entre la machine automotrice (ou le tracteur) et la machine réceptrice ;
— laser ;
— foudre.
Le présent document n'est pas applicable aux niveleuses fabriquées avant la date de publication du présent document par le CEN.
Stroji za zemeljska dela - Varnost - 8. del: Zahteve za grederje
Ta dokument skupaj s 1. delom obravnava vsa večja tveganja za stroje za zemeljska dela – grederje, kadar se uporabljajo v skladu s predvidenim namenom in pod pogoji pričakovane nepravilne uporabe, ki jih določa proizvajalec, v zvezi s celotno življenjsko dobo stroja (glej točko 4).
Zahteve iz tega dela dopolnjujejo splošne zahteve iz standarda
prEN 474-1. Ta dokument ne navaja ponovno zahtev iz standarda prEN 474-1, temveč dodaja ali nadomešča zahteve za uporabo strojev za zemeljska dela – grederjev.
Ta del obravnava tudi grederje, ki so opremljeni s snežnim plugom.
Ta evropski standard se ne uporablja za grederje, izdelane pred datumom izdaje tega evropskega standarda s strani Evropskega odbora za standardizacijo (CEN).

Graders shall comply with the requirements of EN 474-1:2022, as far as not modified or replaced by the
requirements of this part.
There are general requirements specified in EN 474-1:2022 that are not applicable because the risk
assessment has shown that for graders the corresponding hazard does not exist. For graders 4.4.2, 4.5.10,
4.7.3, 4.12, 4.22.5, 4.23, 4.24, Annex B, Annex C and Annex D in EN 474-1:2022, are not applicable.

EN 474-1:2022, 4.15.6 shall apply with the modification given in 4.3.2 below.
4.3.2 Requirements for travelling mode
The leaning front wheel system shall be designed to be mechanically locked in the vertical position.
The frame articulation system shall be designed to be mechanically locked in the straight-frame position.
The implement control system shall be designed so that it can be deactivated (EN 474-1:2022, 4.5.3).
All blades and equipment shall be designed to allow them to be positioned within the defined transport-
width of the machine for travel.
