Earth-moving machinery -- Safety

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.

3.1
compact tool carrier

self-propelled direct-control crawler or wheeled machine having a base machine mass of less than

2 000 kg, having either a pedestrian operating position or a standing operator platform (3.6) at the

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".]
3.2
interchangeable equipment

equipment that an operator can change using the equipment attaching bracket (3.5) to change the

function of the machine
EXAMPLE Loader arm frame, dumper body.
3.3
load carrying attachment
attachment that during its normal use would contain or support a payload
EXAMPLE Bucket, fork, sweeper bucket, grapple fork, concrete mixer.
3.4
non-load carrying attachment
attachment that during its normal use would not contain or support a payload

EXAMPLE Auger, blade, trencher, mower, breaker, tiller, snow blower, soil conditioner.

the base machine
3.6
operator platform

surface provided for a ride-on, standing operator to operate the compact tool carrier (3.1)

3.7
ground-supported operator platform

operator platform (3.6) that pivots about a connection on the base machine and is supported with one

or more trail wheels or skid surfaces that follows the contour of the ground
3.8
powered attachment

attachment that requires power (e.g. hydraulic) from the compact tool carrier (3.1) to operate

4 Safety requirements and protective measures
4.1 General

Compact tool carriers shall comply with the safety requirements and protective measures of

ISO 20474-15:2019(E)
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,

— 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
