European foreword
This document (EN 14492-2:2019) has been prepared by Technical Committee CEN/TC 147 “Cranes -
Safety”, the secretariat of which is held by BSI.
This European Standard shall be given the status of a national standard, either by publication of an
identical text or by endorsement, at the latest by December 2019, and conflicting national standards shall
be withdrawn at the latest by December 2019.
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 14492-2:2006+A1:2009.
CEN/TC 147 WG 17 has reviewed EN 14492-2:2006+A1:2009 to adapt the standard to the technical
progress, new requirements and changes in standards referenced; the main topics are:
— the design and calculation references to EN 13001-1, EN 13001-2 and EN 13001-3-1 are adopeted in
the document FEM-documents FEM 1.001, FEM 9.901 are no longer referenced;
— the design and calculation to EN 13001-3-2, Limit states and proof of competence of wire ropes in
reeving systems is adopted in the document. The standard ISO 4308-1:2003, in the Chapter 5.7 Rope
drives is no longer referenced.
— the design and calculation to EN 13001-3-5, Limit states and proof of competence of forged hooks is
adopted in the document. The standards DIN 15400, UNI 9465 in the Annex H (informative) are no
longer referenced;
— a guidance of relationships between the FEM and ISO-Classification (Hoist Classification) and the
new Classification according to the EN 13001 series is added; see Annex C;
— the EN 14492-2 references to EN 13135;
— this document will supersede EN 14492-2:2006+A1:2009 and the relevant clauses of
EN 14492-1:2006+A1:2009 winches dealing with lifting applications.

Introduction
This European standard is a harmonized standard to provide one means for power driven hoists to
conform to the essential health and safety requirements of the EU Directive 2006/42/EC (Machinery)
and essential safety requirements of EU Directive 2014/34/EU (ATEX).
The machinery concerned and the extent to which hazards, hazardous situations and events are covered
are indicated in the scope of this European Standard.
This European Standard is a type C standard as stated in EN ISO 12100.
When provisions of this type C standard are different from those stated in type A or B standards, the
provisions of this type C standard take precedence over the provision of the other standards, for
machines that have been designed and built according to the provisions of this type C standard.
1 Scope
This document is applicable to the design, information for use, maintenance and testing of power driven
hoists, compact or open construction, with or without trolleys for which the prime mover is an electric,
hydraulic or pneumatic motor. They are designed for the lifting and lowering of loads that are suspended
on hooks or other load lifting attachments. Hoists can be used either in cranes, in other machines, e.g. rail
dependent storage and retrieval equipment, monorail conveyors or by itself.
This document is applicable to the following types of hoist:
a) rope hoist;
b) chain hoist;
c) belt hoist, except belt hoist with steel belts as hoisting media;
d) NGL building hoists including supporting structures;
e) Winches used for lifting operation.
This document is not applicable of the following hazards:
f) this document does not cover hazards related to builders hoists for the transport of goods as defined
in Noise Outdoor Directive (OND) 2000/14/EC;
g) this document does not cover hazards related to the lifting of persons.
This document does not specify additional requirements for hazards related to the use of hoists in
explosive atmospheres in underground mines.
The significant hazards covered by this document are identified in Clause 4.
This document is not applicable to power driven hoists that are manufactured before the date of
publication of this document by CEN.
