European foreword
This document (EN 81-21:2018) has been prepared by Technical Committee CEN/TC 10 “Lifts,
escalators and moving walks”, the secretariat of which is held by AFNOR.
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 September 2018 and conflicting national standards
shall be withdrawn at the latest by September 2018.
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 81-21:2009+A1:2012.
This document has been prepared under a mandate 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.
The main changes with respect to the previous edition (EN 81-21:2009+A1:2012) are as follows:
— updating of references and their associated requirements with regard to EN 81-20:2014;
— removal of duplicated text in reference to the requirements for refuge spaces expressed in
EN 81-20:2014;
— replacement of Annex ZA with regard to the commission mandate M/549/C(2016) 5844 Final and
Directive 2014/33/EU.
This standard is part of the EN 81 series of standards “Safety rules for the construction and installation of
lifts”. This is the second edition.
According to the CEN-CENELEC Internal Regulations, the national standards organizations of the
following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria,
Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia,
France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta,
Netherlands, Norway, Poland, Portugal, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland,

Introduction
This document 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 provisions of the other standards, for
machines that have been designed and built according to the provisions of this type C standard.
The machinery concerned and the extent to which hazards, hazardous situations and events are
covered are indicated in the scope of this document.
Where one or several requirements in EN 81-20:2014 cannot be fulfilled, due to reasons such as the
constraints of the structure of the existing building, the corresponding requirements in this European
Standard apply. According to section 2.2 of Annex I to the Lifts Directive, the application of alternative
measures to prevent the risk of crushing above and underneath the lift car is restricted to installations
where the requirement for free space or refuge is impossible to fulfil and may be subject to prior
approval by national authorities.
The main concern dealt with in this standard is the reduction of top and pit clearances that may be
required due to site conditions. The adopted principle of safety is based on two levels of achievement:
first by means of an electrical stopping of the lift car, then by means of a mechanical stopping of the lift
car.
When drafting this standard, it has been considered for reduced overhead and pit the following:
a) Risk reduction measures that rely solely on operations in compliance with procedures are
considered as not acceptable, except in a few situations in which mistake-proof solutions are not
available (e.g. some activities in repair and installation in which safety devices cannot be
operational);
b) The risk reduction measures are automatically (without any intervention) activated, or may be
manually activated if mistake-proof-by-design, or a combination of both is used.
1 Scope
This European Standard specifies the safety rules related to new passenger and goods/passenger lifts
permanently installed in existing buildings where in some circumstances due to limitations enforced by
building constraints, some requirements of EN 81-20:2014 cannot be met.
This European Standard addresses a number of these constraints and gives requirements for
alternative solutions. It will be read and applied in conjunction with the European Standard
EN 81-20:2014.
This European Standard covers:
— either the construction and installation of one or more complete new lift(s) including new well and
machinery spaces in an existing building; or
— the replacement of one or more existing lift(s) by new ones in existing well(s) and machinery
spaces.
This European Standard does not cover:
— replacement or modifications of some parts to a lift already installed;
— other applications outside of the scope of EN 81-20:2014.

5.5.3.6 When the safety system has been activated, inspection operation shall only be possible if the
movable stops or the triggering device are in the active position.
5.5.3.7 When the safety system has been activated and the movable stops or the triggering device
are not in the active position, emergency electrical operation shall only be possible in down direction.
5.5.4 Visible and/or audible information
On opening by means of a key of any access to the car roof (see 5.5.3.1), a signal visible and/or audible
from the landing shall inform about the positions (active and not active) of:
a) the movable stops; or
b) the triggering device.
If both ends of the travel are protected by the movable stop(s) and/or by pre-triggered stopping
system(s), this information shall allow noticing whether it is from top or bottom end of the well.
The audible signal may be switched off after 60 s provided that the movable stops or the triggering

Movable stops shall comply with the following:
a) the movable stops shall be installed in the pit to mechanically stop the car;
b) the movable stops shall incorporate buffers or act on buffers complying with EN 81-20:2014, 5.8.1
and 5.8.2;
c) automatically operated movable stops shall be designed to prevent damage due to any collision
when they are moved between the fully retracted and extended position.
5.7.2.3 Pre-triggered stopping system
5.7.2.3.1 General
The pre-triggered stopping system shall include a triggering device with its actuation means for
tripping the mechanical stopping gear by a linkage when the car reaches a fixed tripping point in the
down direction.
5.7.2.3.2 The triggering device shall be easily accessible so that examinations and maintenance
operations can be carried out in complete safety from the pit, or from the car roof or from outside of the
well.
5.7.2.3.3 The pre-triggered stopping system shall comply with the following:
a) the stopping gear shall be fixed on the car and act on the guide rails of the car;
b) the stopping gear shall be tripped by a mechanical triggering device using a mechanical linkage for
the tripping operation;
c) the stopping gear shall be kept tripped by the triggering device and the linkage when the car is at
any position below the tripping point.
In case of a release of the stopping gear due to dynamic effects or rescue operations it shall be re-
engaged when the car moves again in down direction below the tripping point keeping the required
refuge space;
d) the stopping gear shall be operated positively:
1) where springs are used they shall act by compression and be guided;
2) where a rope is used the minimum breaking load of the rope shall be related by a safety factor
of at least 8 to the tensile force created during operation of the stopping gear;
e) the force required to activate the stopping gear shall be at least the greater of the following two
values:
1) twice the engagement force of the stopping gear taking into consideration the tolerances due to
friction;
2) 300 N;
f) the stopping gear shall operate an electric safety device in conformity with EN 81-20:2014, 5.11.2,
if it is engaged;
g) when the stopping gear has been tripped, return to normal operation shall require the intervention
of a competent maintenance person;
h) after the release, the stopping gear shall be in a condition to operate;
i) the triggering device shall be protected against the accidental insertion of objects and from dirt and
corrosion, such that its operation is not affected;
j) the pre-triggered stopping system shall be able to stop the car and keep it stopped from any speed
between zero and the tripping speed of the safety gear;
k) the maximum retardation by the stopping gear shall not create a retardation higher than the one
created by the safety gear;
l) when the stopping gear operates, the floor of the car with or without the load uniformly distributed
shall not incline more than 5 % from its normal position;
m) the pre-triggered stopping system shall be designed and verified according to the requirements in
Annex C.
