This document provides specific health and safety requirements of the trenching equipment itself and of the interface (e.g. mechanical, electric, hydraulic, controls) between the carrier-vehicle and its equipment as well as the interaction and effects on each other when used together (e.g. visibility).
This document does not apply to carrier-vehicles which are subject to other relevant regulations.
This document does not deal with continuous surface miners as defined in ISO 19224:2017, truck-trenchers that do not incorporate a vacuum extraction system or self-propelled ride-on and pedestrian controlled floor cutting-off machinery (e.g. ground saw) which are under the scope of EN 13862:2021.
This document does not provide requirements for main electrical circuits and drives of machinery when the primary source of energy is an external electrical supply.
This document does not provide performance requirements for safety related functions of control system(s).
The following significant and relevant hazards are not covered in this document:
— Transmission of power between self-propelled machinery (or tractor) and recipient machinery;
— Laser;
— Lightning.
This document is not applicable to trenchers which are manufactured before the date of publication of this document by CEN.

Stroji za zemeljska dela - Varnost - 10. del: Zahteve za rovokopače
Ta del standarda prEN 474 obravnava vsa večja tveganja, nevarne situacije in nevarne dogodke v zvezi z rovokopači iz standarda EN ISO 6165:2012 in rovokopači z mehanizirano polagalno enoto, kadar se uporabljajo v skladu s predvidenim namenom in pod pogoji pričakovane nepravilne uporabe, ki jih določa proizvajalec (glej točko 4). Obravnava:
– integrirane rovokopače z lastnim pogonom;
– kombinacije nosilnega vozila (tovornjak, traktor, posebno vozilo) in priključka za kopanje rovov;
– zamenljivo opremo za kopanje rovov, ki je nameščena na izvedenih strojih (npr. mini nakladalnik ali nosilno vozilo).
– Za integrirane rovokopače na lastni pogon ta del obravnava vse posebne zdravstvene in varnostne zahteve.
– Za stroje, ki so kombinacija nosilnega vozila in priključka za kopanje rovov, ki je del vozila (npr. tovornjaka) oziroma je na njem nameščen (npr. na traktorju), ta del standarda prEN 474 obravnava posebne zdravstvene in varnostne zahteve tako za uporabo priključka kot tudi vmesnega elementa (npr. mehanskega, električnega, hidravličnega, krmilnega) med nosilnim vozilom in njegovim priključkom ter nujno medsebojno delovanje in učinke, ki jih imata drug na drugega, kadar se uporabljata skupaj (npr. stabilnost, vidljivost).
OPOMBA: Za nosilna vozila veljajo drugi predpisi (npr. cestni predpisi).
– Za izvedene stroje ta del obravnava posebne zdravstvene in varnostne zahteve za uporabo zamenljive opreme in vmesnega elementa z izvedenimi stroji oziroma z nosilnim vozilom.
– Za te stroje ta del ne obravnava strojev za zemeljska dela, za katere lahko veljajo drugi standardi (npr. standard prEN 474-3 za mini nakladalnike, standard prEN 474-4 za bagre).
Ta evropski standard ne obravnava strojev za neprekinjeno površinsko rudarjenje iz standarda ISO/CD 19224, rovokopačev na tovornjaku, ki ne vključujejo sistema za vakuumsko ekstrakcijo, ter talnih rezalnikov z lastnim pogonom, upravljanih med vožnjo na stroju ali s tal (npr. talna žaga), ki spadajo na področje uporabe standarda EN 13862.
Ta dokument skupaj s 1. delom obravnava vsa večja tveganja za stroje za zemeljska dela – rovokopače, 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 rovokopačev.
Ta evropski standard se ne uporablja za rovokopače, 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.
