Earth-moving machinery -- Safety

ISO 20474-13:2017 gives the safety requirements specific to rollers as defined in ISO 6165. It is intended to be used in conjunction with ISO 20474‑1, which specifies general safety requirements common to two or more earth-moving machine families. The specific requirements given in this document take precedence over the general requirements of ISO 20474‑1. ISO 20474-13:2017 deals with all significant hazards, hazardous situations and events relevant to the earth-moving machinery within its scope (see ISO 20474‑1:2017, Annex A) when used as intended or under conditions of misuse reasonably foreseeable by the manufacturer. It specifies the appropriate technical measures for eliminating or reducing risks arising from relevant hazards, hazardous situations or events during commissioning, operation and maintenance. ISO 20474-13:2017 is not applicable to machines manufactured before the date of its publication.

Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national standards

bodies (ISO member bodies). The work of preparing International Standards is normally carried out

through ISO technical committees. Each member body interested in a subject for which a technical

committee has been established has the right to be represented on that committee. International

organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.

ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of

electrotechnical standardization.

The procedures used to develop this document and those intended for its further maintenance are

described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the

different types of ISO documents should be noted. This document was drafted in accordance with the

editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).

Attention is drawn to the possibility that some of the elements of this document may be the subject of

patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of

any patent rights identified during the development of the document will be in the Introduction and/or

on the ISO list of patent declarations received (see www .iso .org/ patents).

Any trade name used in this document is information given for the convenience of users and does not

constitute an endorsement.

expressions related to conformity assessment, as well as information about ISO’s adherence to the

World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT) see the following

This document was prepared by Technical Committee ISO/TC 127, Earth-moving machinery,

Subcommittee SC 2, Safety, ergonomics and general requirements.

This second edition cancels and replaces the first edition (ISO 20474-13:2008), which has been

technically revised with the following changes:

— references to national and regional provisions in the withdrawn ISO/TS 20474-14 have been deleted;

— safety requirements and protective measures have been updated.
It is intended to be used in conjunction with ISO 20474-1.

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

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 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.

ISO 20474 provides acceptable safety requirements for earth-moving machinery. This standard does

not necessarily provide requirements to meet all national and regional regulatory provisions, e.g. Japan

does not allow object handling with earth-moving machinery.
