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.

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.

4 Safety requirements and/or protective/risk reduction measures
4.1 General
4.1.1 Context

Pipelayers shall comply with the safety requirements and/or protective/risk reduction measures of this

clause. In addition, the machines shall be designed according to the principles of EN ISO 12100:2010 for

Pipelayers shall comply with the requirements of EN 474-1:2022, as far as not modified or replaced by

the requirements of this part.

There are general requirements specified in EN 474-1:2022 that are not applicable because the risk

assessment has shown that for pipelayers the corresponding hazard does not exist. For pipelayers 4.2.2,

4.4.2, 4.5.10, 4.7.3, 4.10, 4.14.2.3, 4.22.5, 4.23, 4.24, Annex B and Annex D in EN 474-1:2022, are not

applicable.
4.2 Operator’s station
4.2.1 General
EN 474-1:2022, 4.3 shall apply with the addition stated in 4.2.2 below.
4.2.2 Window(s)

EN 474-1:2022, 4.3.2.5 shall apply with the addition that pipelayers shall be provided with motorised

wiper(s) and washer in the travelling and lifting (e.g. side boom application) directions.

4.3 Seat
4.3.1 General
EN 474-1:2022, 4.4.1.4 shall apply with the addition stated in 4.3.2 below.

0,5 m/s shall be equipped with a suspended seat complying with EN ISO 7096:2020 class EM6. As an

alternative without testing the machine, the pipelayers shall be equipped with a suspended seat

complying with EN ISO 7096:2020 class EM6.
NOTE RMS means root mean square.
4.4 Operator's controls and indicators
4.4.1 General
EN 474-1:2022, 4.5 applies with the following modifications in 4.4.2 below.
4.4.2 Emergency attachment lowering (Free fall function)

The emergency device to release the load shall be reachable by the operator within the cabin, according

to EN ISO 6682:2008.

The free fall function should be used only for emergency purposes and not for normal working purposes

(e.g. fast lowering).

SIST EN 474-9:2022
EN 474-9:2022 (E)
4.5 Visibility
EN 474-1:2022, 4.8 applies with the following additions:

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.
This requirement may be fulfilled either e.g.:
— by providing a seat turned to the direction of the boom, or
— by providing a slewable and lockable seat to the direction of the boom.
4.6 Lifting operation
4.6.1 General

EN 474-1:2022, 4.12 shall apply with the additions stated in 4.6 of this document.

4.6.2 Lifting capacity
Lifting equipment shall meet all the requirements in ISO 8813:1992.
4.6.3 Load lowering speed

A device to control the lowering speed of the boom and the hook shall be fitted so that the operator can

control movement of the load with modulation and is able to stop the load at all load conditions up to and

including rated lift capacity during normal operating conditions.
NOTE Emergency attachment lowering is covered in 4.4.2 of this document.
4.6.4 Pipe laying brakes

The pipe laying system shall be fitted with brakes which can be released by controls and automatically

applied when the operator stops actuating or when the power source fails. The brakes shall be designed

to withstand 1,5 times the rated lift capacity under conditions

Introduction
This part of prEN 474 is a type C standard as stated in EN ISO 12100:2010.

The machinery concerned and the extent to which hazards, hazardous situations and events are covered

are indicated in the scope of this European Standard.

When provisions of this type C standard are different from those which are stated in type A or B

standards, the provisions of this type C standard take precedence over the provisions of the other

standards, for machines that have been designed and built according to the provisions of this type C

standard.
1 Scope

This part of prEN 474 deals with all significant hazards, hazardous situations and events relevant to

pipelayers as defined in EN ISO 6165:2012 when they are used as intended and under conditions of

misuse which are reasonably foreseeable by the manufacturer (see Clause 4).

The requirements of this part are complementary to the common requirements formulated in

prEN 474-1:2017.

This part does not repeat the requirements from prEN 474-1:2017 but adds or replaces the requirements

for application for pipelayers.

This part specifies the appropriate technical measures to eliminate or reduce risks arising from the

significant hazards, hazardous situations and events during commissioning, operation and maintenance

of pipelayers.
This part specifies additional requirements for rear mounted winches.

Pipelayers with rotating upper structure are excluded from the scope of this document. This European

Standard is not applicable to pipelayers manufactured before the date of publication of this European

Standard by CEN.
