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).

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.

rear of the machine and either front-mounted interchangeable equipment (3.2) or lift arms with a quick
coupler capable of coupling to interchangeable, front-mounted attachments
[SOURCE: ISO 6165:2012, 4.13, modified — The mass has been increased and changed to “base machine”
and the term “attachment bracket” has been updated to “quick coupler".]

4.2 Compact tool carriers with operator platform
ISO 20474-1:2017, 4.2, is replaced by the following.
a) An operator platform, if provided, shall have
— a durable, slip-resistance surface,
— a maximum height of 400 mm above the ground reference plane,
2
— a surface area of at least 1 355 cm and shall be capable of containing a circle with a minimum
diameter of 360 mm or minimum dimensions of 430 mm in width by 315 mm in depth. The
operator platform does not need to be continuous in its width, provided the standing area for
each foot has a minimum dimension of 160 mm in width.
b) Compact tool carriers with an operator platform shall have a handhold in accordance with ISO 2867
to facilitate ingress and egress from the platform.
c) A ground-supported or folding operator platform shall automatically lock in the operating position
when the operator platform is lowered, or upward rotation of the operator platform shall be limited
to provide clearance for the operator between structural components of the base machine and the
pivoting platform. Both small and large operator human physical dimensions in accordance with
ISO 3411 shall be considered.
If the compact tool carrier with a pedestrian operator position has a provision to add an operator
platform, the platform shall be designed to mee
