- Scope and exclusions: Applies to new passenger and goods-passenger lifts (traction, positive drive, hydraulic) - excludes certain drive types, very low-speed lifts (≤ 0.15 m/s), some hydraulic limits, lifts in existing buildings where building constraints prevent compliance, and specialized lifting appliances (e.g., paternosters, mine lifts, construction-site hoists).
- Well, machinery spaces and pulley rooms: Access, arrangement and protective measures for safe installation and maintenance.
- Landing and car doors: Dimensions, locking, interlocks, emergency unlocking and protective devices.
- Car and counterweight design: Car dimensions, rated load, materials, roof equipment, ventilation and lighting.
- Suspension and compensation: Ropes, chains, sheaves, rope terminations and load distribution.
- Protection against free fall and overspeed: Safety gear, rupture valves, restrictors, pawl devices and overspeed protection.
- Guide rails and buffers: Guiding, stresses, deflections, impact factors and buffer stroke requirements.
- Lift machinery and hydraulics: Requirements for traction machines, positive drive machines and hydraulic units.
- Electrical installations and safety devices: Wiring, protection, safety circuits, switches and earthing.
- Controls and safety verification: Operational controls, final limit switches, emergency communication and verification of safety measures, including examinations and tests before putting into service.
Practical applications and users

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 CEN/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 ensured 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 ensured, 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:
a) 300 N;
b) 1000 N where impact can occur.
0.4.12 With the exception of the items listed below which have been given special consideration, a
mechanical device built according to good practice and the requirements of the standard, including
uncontrolled slipping of the ropes on the traction sheave will not deteriorate to a point of creating
hazard without the possibility of detection provided that all of the instructions given by the
manufacturer have been duly applied:
a) breakage of the suspension;
b) breakage and slackening of all linkage by auxiliary ropes, chains and belts;
c) failure of one of the mechanical components of the electromechanical brake which take part in the
application of the braking action on the drum or disk;
d) failure of a component associated with the main drive elements and the traction sheave;
e) rupture in the hydraulic system (jack excluded);
f) small leakage in the hydraulic system (jack included, see 6.3.10).
0.4.13 The possibility of the safety gear not engaging, should the car free fall from a stationary position
at the lowest landing, before the car strikes the buffer(s) is considered acceptable.
0.4.14 When the speed of the car is linked to the electrical frequency of the mains, the speed is
assumed not to exceed 115 % of the rated speed or a corresponding lesser speed where specified in this
standard for inspection control, levelling, etc.
0.4.15 Means of access are provided for the hoisting of heavy equipment (see 0.4.2 e)).
0.4.16 To ensure the correct functioning of the equipment in the well and machinery space(s), i.e.
taking into account the heat dissipated by the equipment, the ambient temperature in the well and the
machinery space(s) is assumed to be maintained between + 5 °C and + 40 °C.
NOTE See HD 60364-5-51, Code AA5.
0.4.17 The well is suitably ventilated, according to national building regulation, taking into
consideration the heat output as specified by the manufacturer, the environmental conditions of the lift
and the limits given in 0.4.16, e.g. ambient temperature, humidity, direct sunlight, air quality and air
tightness of buildings due to energy saving requirements.
NOTE See 0.4.2 and E.3 for further guidance.
0.4.18 Access ways to the working areas are adequately lit (see 0.4.2).
0.4.19 Minimum passageways, corridors, fire escapes, etc. are not obstructed by the open door/trap of
the lift and/or any protection means for working areas outside of the well, where fitted according to the
maintenance instructions (see 0.4.2).
0.4.20 Where more than one person is working at the same time on a lift, an adequate means of
communication between these persons is ensured.
0.4.21 The fixing system of guards, used specifically to provide protection against mechanical,
electrical or any other hazards by means of a physical barrier, which have to be removed during regular
maintenance and inspection, remains attached to the guard or to the equipment when the guard is
removed.
0.4.22 The fluids used for the operation of hydraulic lifts are according to EN ISO 6743-4.
1 Scope
1.1 This document 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 document, supplementary requirements have to 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;
1)
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.
1)
Existing building is a building which is used or was already used before the order for the lift was placed. A building whose
internal structure is completely renewed is considered as a new building.
