Safety rules for the construction and installation of lifts - Lifts for the transport of persons and goods - Part 20: Passenger and goods passenger lifts
1.1 This standard specifies the safety rules for permanently installed new passenger or goods passenger lifts, with traction, positive or hydraulic drive, serving defined landing levels, having a car designed for the transportation of persons or persons and goods, suspended by ropes, chains or jacks and moving between guide rails inclined not more than 15° to the vertical.
1.2 In addition to the requirements of this standard, supplementary requirements shall be considered in special cases (use of lifts by persons with disabilities, in case of fire, potentially explosive atmosphere, extreme climate conditions, seismic conditions, transporting dangerous goods, etc.).
1.3 This standard does not cover:
a) lifts with:
1) drive systems other than those stated in 1.1;
2) rated speed ≤ 0,15 m/s;
b) hydraulic lifts:
1) with a rated speed exceeding 1 m/s;
2) where the setting of the pressure relief valve (5.9.3.5.3) exceeds 50 MPa;
c) new passenger or goods passenger lifts in existing buildings ) where in some circumstances due to limitations enforced by building constraints, some requirements of EN 81-20 cannot be met and EN 81-21 should be considered;
d) lifting appliances, such as paternosters, mine lifts, theatrical lifts, appliances with automatic caging, skips, lifts and hoists for building and public works sites, ships' hoists, platforms for exploration or drilling at sea, construction and maintenance appliances or lifts in wind turbines;
e) important modifications (see Annex C) to a lift installed before this standard is brought into application;
f) safety during operations of transport, erection, repairs, and dismantling of lifts.
However, this standard may usefully be taken as a basis.
Noise and vibrations are not dealt with in this standard as they are not found at levels which could be considered as harmful with regard to the safe use and maintenance of the lift (see also 0.4.2).
1.4 This standard is not applicable to passenger and goods passenger lifts, which are installed before the date of its publication.
Sicherheitsregeln für die Konstruktion und den Einbau von Aufzügen - Aufzüge für den Personen- und Gütertransport - Teil 20: Personen- und Lastenaufzüge

Within CEN/TC 10 an interpretation committee has been established to answer questions about the spirit in which the
experts have drafted the various clauses of this standard. All such interpretations are published within CEN TS 81-11 until
incorporated by amendment into the standards concerned.
0 Introduction
0.1 General
This standard is a type C standard as stated in EN ISO 12100.
The machinery concerned and the extent to which hazards, hazardous situations and hazardous events are
covered are indicated in the scope of this 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.
0.2 General remarks
0.2.1 The object of this standard is to define safety rules related to passenger and goods passenger lifts
with a view to safeguarding persons and objects against the risk of accidents associated with the normal use,
maintenance and emergency operation of lifts.
0.2.2 A study has been made of the various possible hazards with lifts, see Clause 4.
0.2.2.1 Persons to be safeguarded:
a) users, including passengers and competent and authorized persons, e.g. maintenance and inspection
personnel (see EN 13015);
b) persons in the surrounding area of the well, or any machine room and pulley room, who may be effected
by the lift.
0.2.2.2 Property to be safeguarded:
a) loads in car;
b) components of the lift installation;
c) building in which the lift is installed;
d) the immediate surrounding area of the lift installation.
NOTE EN 81-71 gives additional requirements covering lifts resistant to acts of vandalism and EN 81-77 gives
additional requirements covering lifts in seismic conditions.
0.2.3 When the weight, size and/or shape of components prevent them from being moved by hand, they
are:
a) either fitted with attachments for lifting gear; or
b) designed so that they can be fitted with such attachments (e.g. by means of threaded holes); or
c) shaped in such a way that standard lifting gear can easily be attached.
0.3 Principles
0.3.1 General
In drawing up this standard the following principles have been used:
0.3.2 This standard does not repeat all the general technical rules applicable to every electrical,
mechanical, or building construction including the protection of building elements against fire.
It has, however, been necessary to establish certain requirements of good construction, either because they
are peculiar to lift manufacture or because in the case of lift utilization the requirements may be more stringent
than elsewhere.
0.3.3 This standard states minimum rules for the installation of lifts into buildings/constructions. There may
be in some countries regulations for the construction of buildings etc. which cannot be ignored.
Typical clauses affected by this are those defining minimum values for the height of the machine and pulley
rooms and for their access doors dimensions.
0.3.4 As far as possible the standard sets out only the requirements that materials and equipment have to
meet in the interests of safe operation of lifts.
0.3.5 Risk analysis, terminology and technical solutions have been considered taking into account the
methods of EN ISO 12100, EN ISO 14798 and the EN 61508 series of standards.
0.3.6 In order for EN 81-20 to be a widely applicable standard the average weight of a person has been
determined to be 75 kg.
This standard defines the maximum car area related to a specified design load in the car (rated load) and the
minimum car area to transport a corresponding number of persons, based on 75 kg per person, in order to
detect and discourage overloading.
0.4 Assumptions
0.4.1 General
In drawing up this standard the following assumptions have been made:
0.4.2 Negotiations have been made between the customer and the supplier and agreement reached about:
a) the intended use of the lift;
b) the type and mass of the handling devices intended to be used to load and unload the car in the case of
goods passenger lifts;
c) environmental conditions such as temperature, humidity, exposure to sun or wind, snow, corrosive
atmosphere;
d) civil engineering problems (for example, building regulations);
e) other aspects related to the place of installation;
f) the dissipation of heat from the components / equipment of the lift which would require ventilation of the
well and/or the machinery space / location of equipment;
g) information concerning the aspects relating to noise and vibrations emitted by the equipment.
0.4.3 Relevant risks have been considered for each component that may be incorporated in a complete lift
installation and rules have been drawn up accordingly:
Components are:
a) designed in accordance with usual engineering practice (see FprCEN/TR 81-12) and calculation codes,
taking into account all failure modes;
b) of sound mechanical and electrical construction;
c) made of materials with adequate strength and of suitable quality;
d) free of defects;
e) free from harmful materials, e.g. asbestos.
0.4.4 Components are kept in good repair and working order, so that the required dimensions remain
fulfilled despite wear. All lift components are considered as requiring inspection to ensure safe continued
operation during their use.
The operational clearances specified in the standard should be maintained not only during the examination
and tests before the lift is put into service, but also throughout the life of the lift.
NOTE Components not requiring maintenance (e.g. maintenance free, sealed for life) are still required to be available
for inspection.
0.4.5 Components will be selected and installed so that foreseeable environmental influences and special
working conditions do not affect the safe operation of the lift.
0.4.6 By design of the load bearing elements, safe normal operation of the lift is assured for loads ranging
from 0 % to 100 % of the rated load, plus any designed overload capacity (see 5.12.1.2).
0.4.7 The requirements of this standard are such that the possibility of a failure of an electric safety device
(see 5.11.2) or a type tested safety component complying with all the requirements of this standard and
EN 81-50 needs not to be taken into consideration.
0.4.8 Users have to be safeguarded against their own negligence and unwitting carelessness when using
the lift in the intended way.
0.4.9 A user may, in certain cases, make one imprudent act. The possibility of two simultaneous acts of
imprudence and/or the abuse of instructions for use is not considered.
0.4.10 If in the course of maintenance work a safety device, normally not accessible to the users, is
deliberately neutralized, safe operation of the lift is no longer assured, but compensatory measures will be
taken to ensure users safety in conformity with maintenance instructions.
It is assumed that maintenance personnel are instructed and work according to the instructions.
0.4.11 Horizontal forces and/or energies to consider are indicated in the applicable clauses of the standard.
Typically, where not otherwise specified in this standard, the energy exerted by a person results in an
equivalent static force of:
