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

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.

European foreword

This document (prEN 474-6:2017) has been prepared by Technical Committee CEN/TC 151

“Construction equipment and building material machines - Safety”, the secretariat of which is held by

DIN.
This document is currently submitted to the CEN Enquiry.
This document will supersede EN 474-6:2006+A1:2009.

This document has been prepared under a mandate given to CEN by the European Commission and the

European Free Trade Association, and supports essential requirements of EU Directive(s).

For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this

document.
For bibliographic references, see prEN 474-1:2017.
prEN 474 ”Earth-moving machinery — Safety” comprises the following parts:
— Part 1: General requirements
— Part 2: Requirements for tractor-dozers
— Part 3: Requirements for loaders
— Part 4: Requirements for backhoe-loaders
— Part 5: Requirements for hydraulic excavators
— Part 6: Requirements for dumpers
— Part 7: Requirements for scrapers

Introduction
This part of prEN 474 is a type C standard as stated in EN ISO 12100:2010.

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

covered are indicated in the scope of this document.

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

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

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

standard.
1 Scope

This document, together with part 1, deals with all significant hazards for earth-moving machinery –

dumpers 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 – dumpers.

This document is not applicable to dumpers manufactured before the date of publication of this

European Standard by CEN.

This part does not repeat the requirements from prEN 474-1:2017, but adds or replaces the

requirements for application for dumpers.

This part specifies the appropriate technical measures to eliminate or reduce risks arising from the

significant hazards, hazardous situations and events during commissioning, operation and maintenance

of dumpers.
Pedestrian controlled dumpers are excluded from scope of this European Standard.

This European Standard is not applicable to dumpers, manufactured before the date of publication of

this European Standard by CEN.
