Earth-moving machinery — Safety — Part 15: Requirements for compact tool carriers
This document gives the safety requirements specific to compact tool carriers. 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. This document 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. This document 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.

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 in accordance with 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.

earth-moving machine families. The specific requirements given in this document take precedence
over the general requirements of ISO 20474-1.
This document 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.
