identical text or by endorsement, at the latest by September 2022, and conflicting national standards shall
be withdrawn at the latest by March 2024.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN shall not be held responsible for identifying any or all such patent rights.
This document supersedes EN 474-9:2006+A1:2009.
This document has been prepared under a standardization request given to CEN by the European
Commission and the European Free Trade Association, and supports essential requirements of
EU Directive(s).
For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this
document.

— Part 9: Requirements for pipelayers
— Part 10: Requirements for trenchers
— Part 11: Requirements for earth and landfill compactors
— Part 12: Requirements for cable excavators
— Part 13: Requirements for rollers
This document is intended for use in combination with part 1 of the series.
The main differences between this document and EN 474-9:2006+A1:2009 are as follows:
a) the normative references (Clause 2) (updated);
b) safety related functions of control systems (excluded);
c) pipelayers shall be equipped with cab, and ROPS, TOPS (4.2) (added);
d) windows shall be provided with motorised wiper(s) and washer in the travelling and lifting (e.g. side
boom application) directions (4.2.2) (added);
e) means shall be provided to ensure operator visibility to the pipe area from the operator station
during the lifting, translation operations and combination of both (4.5) (added);
f) pipelayers are equipped with Load capacity indicator and warning device, Rated capacity limiting,
Hoisting limiter device and Lowering limiter (4.6) (added);
g) the load capacity indicator shall take in account the ground slope condition and provide information
about weight of load and weight rated capacity (4.6.7) (added);
h) pipelayers with a lifting hoist shall be fitted with a lowering limiter. As a minimum, the lowering
limiter shall ensure three turns of rope on the drum. (4.6.10) (added);
i) if a pipelayer is equipped with a rear mounted winch, ISO 19472:2006 shall be used as guidance for
design. (4.7.1) (added);

Introduction
This document is a type-C standard as stated in EN ISO 12100.
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.
1 Scope
This document, together with EN 474-1:2022, deals with all significant hazards, hazardous situations and
events relevant to pipelayers as defined in 3.1, when used as intended and under the conditions of misuse
which are reasonably foreseeable by the manufacturer (see Annex A) associated with the whole lifetime
of the machine as described in EN ISO 12100:2010, 5.4.
The requirements of this document are complementary to the common requirements formulated in
EN 474-1:2022. This document does not repeat the requirements of EN 474-1:2022 but supplements or
modifies the requirements for pipelayers.
This document also specifies additional requirements for rear mounted winches.
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.
Pipelayers with rotating upper structure are excluded from the scope of this document.
This document is not applicable to pipelayers manufactured before the date of publication of this
document by CEN.
