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

Dieser Teil von prEN 474 ist eine Typ-C-Norm nach EN ISO 12100:2010.
Auf die betreffenden Maschinen und die behandelten Gefährdungen, Gefährdungssituationen und Gefährdungsereignisse wird im Anwendungsbereich dieser Europäische Norm hingewiesen.
Für Maschinen, die nach den Festlegungen dieser Typ-C-Norm konzipiert und gebaut worden sind, gilt: Wenn die Festlegungen in dieser Typ-C-Norm von den Festlegungen in Typ-A- oder -B-Normen abweichen, haben die Festlegungen dieser Typ-C-Norm Vorrang gegenüber den Festlegungen der anderen Normen.

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).

Introduction
This document is a type-C standard as stated in EN ISO 12100:2010.

This document is of relevance, in particular, for the following stakeholder groups representing the market

players with regard to machinery safety:
— machine manufacturers (small, medium and large enterprises);

— health and safety bodies (regulators, accident prevention organizations, market surveillance, etc.).

Others can be affected by the level of machinery safety achieved with the means of the document by the

above-mentioned stakeholder groups:
— machine users/employers (small, medium and large enterprises);

— machine users/employees (e.g. trade unions, organizations for people with special needs);

— service providers, e.g. for maintenance (small, medium and large enterprises);
— consumers (in case of machinery intended for use by consumers).

The above-mentioned stakeholder groups have been given the possibility to participate at the drafting

process of this document.

The machinery concerned and the extent to which hazards, hazardous situations or hazardous events are

covered are indicated in the scope of this document.

When requirements of this type-C standard are different from those which are stated in type-A or type-B

standards, the requirements of this type-C standard take precedence over the requirements of the other

standards for machines that have been designed and built according to the requirements of this type-C

standard.

grader

self-propelled wheeled machine with an adjustable blade positioned between the front and rear axles,

which can be equipped with a front-mounted blade or scarifier that can also be located between the front

and rear axles

Note 1 to entry: The machine is primarily designed for grading, sloping, ditching and the scarifying of materials

4 Safety requirements and/or protective/risk reduction measures
4.1 General
4.1.1 Context

Graders shall comply with the safety requirements and/or protective/risk reduction measures of this

clause. In addition, the machines shall be designed according to the principles of EN ISO 12100:2010 for

relevant but not significant hazards which are not dealt with by this document.
4.1.2 Specific relation to EN 474-1

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.

4.2 Seat

EN 474-1:2022, 4.4.1 shall apply with the addition that the seat shall meet the requirements of

EN ISO 7096:2020, tested with the input spectral class of EM4.
4.3 Transportation
4.3.1 General
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.
4.4 Steering system
