European foreword
This document (prEN 17639:2021) has been prepared by Technical Committee CEN/TC 242 "Safety
requirements for cableway installations designed to carry persons", the secretariat of which is held by
AFNOR (Association Française de Normalisation — the French national organisation for
standardisation).
This document has been submitted for the purposes of the CEN (Comité Européen de Normalisation —
European Committee for Standardization) enquiry.
This document has been prepared as part of a standardisation mandate issued by the European
Commission and the European Free Trade Association CEN and supports basic requirements of
EU-Directive 2006/42/EC.
For the context of EU guidelines, see informative Annex ZA, which forms an integral part of this document.

Introduction
This document is a Type C standard, as defined in EN ISO 12100:2010.
The affected cableways and the hazards covered are defined within the scope of this document.
In preparing this standard, it was assumed that:
a) negotiations have taken place between the operator and the manufacturer about specific conditions
of use and the place of use of the cableway in terms of health and safety;
b) only qualified individual operate, clean, check, maintain, inspect and repair cableways;
c) the installation site allows the cableway to be operated safely;
d) no components have specific requirements:
1) have been made from material of adequate strength and durability and of appropriate quality;
2) operate mechanically without any faults;
3) have been measured in line with standard engineering expertise and calculation methods,
including all types of malfunction and taking into account appropriate safety factors.
e) the geological conditions have been determined and taken into account in accordance with standard
engineering expertise and calculation methods.
In the event that requirements under this Type C standard differ from those specified in Type A and Type
B standards, the requirements of this Type C standard will take precedence.
This document covers cableways for the transport of material and specially designated persons. These
cableways are intended exclusively to open up the area in order to supply goods and dispose of waste as
well as to sustain operations that are difficult to access. Supplying mountain huts and shelters is an
example of operational concern/how a cableway installation of this kind can be used.
Employees and the immediate family members of the operator, as well as persons connected to the
operator's actual operational activities at the site of the installation or who need to be transported in the
public interest may be included in the list for carriage for in-house reasons.
NOTE Transporting a larger group of people is only permitted if cableways in accordance with Regulation
(EU) 2016/424 are used.

1 Scope
This Type C standard document applies to fixed cableways operating as single-cable or bi-cable aerial
ropeways operating on a single-track or dual-track for the transport
— of goods to supply goods to and dispose of waste from mountain huts and shelters and
— of specially designated persons.
This document does not apply to:
— cableways primarily designed, constructed or operated mainly for the transport of persons and
subject to Regulation (EU) 2016/424;
— portable cableways;
— lifts;
— funicular railways;
— fixed and portable equipment used exclusively for leisure and pleasure purposes and not for the
transport of persons;
— water ski lifts;
— agricultural and forestry installations;
— rope crane installations and crane installations;
— mining installations or other installations set up and used for industrial purposes;
— drilling equipment.
This document deals with the significant hazards arising from the construction and operation of the
aforementioned cableways and measures to eliminate or reduce these hazards, provided that these
cableways are used in accordance with their intended purpose and that the remaining residual risk has
been anticipated and accepted by the manufacturer. A full list of all risks considered
under EN ISO 12100:2010 is shown at Annex A.
The requirements under this document do not apply to equipment and systems manufactured or placed
on the market before the date that this document is published.
In the event that there are changes to the existing cableways, these changes must be assessed in terms of
their impact on safety in accordance with EN ISO 12100:2010. If this assessment shows that the intended
changes do not constitute a significant change pursuant to the Machinery Directive, the requirements
under this document must in all cases be fulfilled by the assemblies/components concerned.
In the following sections, for reasons of simplification, the term cableway is used on its own to cover the
types of equipment covered by this standard.
This document does not cover:
— hazards caused by noise;
— hazards caused by vibration;
— hazards caused by explosion;

— hazards caused by electromagnetic influences (EMC).
NOTE Directive 2014/30/EU regarding electromagnetic compatibility may be used for machinery or
components in accordance with this standard. This standard is not intended as a means of proving compliance with
the basic health and safety requirements of the aforementioned directive or the aforementioned hazards.

4 List of significant hazards
4.1 General
Section 4 covers all significant hazards, hazardous situations and circumstances that have been identified
as relevant to the field of application specified in the scope of application as a result of a risk assessment
and which require provisions to eliminate or reduce the risk A full list of all hazards under
EN ISO 12100:2010 is shown in Annex A. The clarifying remarks form the basis for the safety measures
under Section 5.
On the basis of the description of intended use for the cableway in a specification (user agreement,
see 6.4) the conditions to be accepted for the cableway to operate must be defined. Before this standard
is applied, a risk assessment must be carried out for the respective cableway, its intended use and location
to ensure that all hazards have been recorded.
Cableways must be designed, dimensioned and constructed in such a way that they can be operated safely
taking into account the type of cableway, the characteristics of the terrain and the surrounding area, the
atmospheric and meteorological conditions, structures and obstacles on the ground that may be located
in the vicinity and in mid air and the natural hazards (such as avalanches, rockfall).
Assembly and maintenance must be able to be carried out safely.
There may be exceptions to the requirements under this standard. These exceptions must be justified by
means of a risk assessment in accordance with EN ISO 12100:2010 and at least an equivalent level of
safety must be achieved.
