0 Introduction
0.1 General
This document is a type C standard as stated in EN ISO 12100.
The machinery concerned and the extent, to which hazards, hazardous situations and 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.
The purpose of this standard is to define safety requirements for inclined lifts in order to safeguard
persons and objects against risks of accidents during installation, operation, maintenance, inspection
work and emergency operations of lifts.
0.2 Considerations
Consideration has been taken into account of various categories of lifts with inclined travel path to
ascertain the related hazards and risks owing to the configuration of structures (civil engineering
works), inclination and outside influences such as the following:
a) the large opening to the exterior;
b) the possibility to walk around inside the lift well;
c) the arrangement of the doors;
d) the horizontal component of deceleration in the event of stopping of the vehicle.
The prescriptions relating to the protection of workers and to the evacuation from the car are different
when it is possible to walk inside the well and when the car roof is used as working station for the
maintenance.
An Interpretation Committee has been established to clarify, if necessary, the spirit in which the clauses
of the document have been drafted and to specify the requirements appropriate to particular cases.
Interpretation Requests can be sent to the National Standard Bodies which will contact the responsible
Technical Committee CEN/TC 10 (see CEN/TR 81-10 [1] for information).
0.3 Principles
In drawing up this standard the following have been used.
This document 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, seemed 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.
This document does not only address the essential safety requirements of the Lift Directive, but
additionally 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.

---------------------- Page: 8 ----------------------
SIST EN 81-22:2021
EN 81-22:2021 (E)
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.
As far as possible the document sets out only the requirements that materials and equipment will meet
in the interests of safe operation of lifts.
0.4 Assumptions
The contents of this document are based on the assumption that persons using inclined lifts are able to
do so unaided.
It is assumed that negotiations have been made for each contract between the customer and the
supplier/installer (see also Annex O) about:
a) intended use of the inclined lift;
b) environmental conditions;
c) civil engineering problems;
d) other aspects relating to the place of installation (e.g. high-voltage electric line, bridges, dangerous
buildings, natural obstacle).
Possible risks have been considered of each component that may be incorporated in a complete lift
installation. Rules have been drawn up accordingly.
Components are:
— designed in accordance with usual engineering practice and calculation codes, taking into account
all failure modes;
— of sound mechanical and electrical construction;
— made of materials with adequate strength and of suitable quality;
— be free of defects.
Harmful materials, such as asbestos are not used.
Components are kept in good repair and working order, so that the required dimensions remain
fulfilled despite wear.
Components will be selected and installed so that foreseeable environmental influences and special
working conditions do not affect the safe operation of the lift.
Especially for the extreme temperatures which were agreed between the customer and the supplier, the
choice of materials and components will be made with particular attention that they keep their
characteristics for impact strength for the steel, rigidity and function for plastics, functional for the
electronic components, viscosity for oils, etc.
By design of the load bearing elements, a safe operation of the lift is ensured for loads ranging up to
125 % (static) and up to 110 % (dynamic) of the rated load.

EN 81-22:2021 (E)
The requirements of this document regarding electrical safety devices are such that the possibility of a
failure of an electric safety device (see 5.11.1.2) complying with all the requirements of this document
need not be taken into consideration.”
Users should be safeguarded against their own negligence and unwitting carelessness when using the
lift in the intended way.
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.
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 is instructed and works according to the instructions.
Horizontal forces and/or energies to consider are indicated in the applicable clauses of the standard.
Typically:
— the static force that a person normally exerts is of the magnitude of 300 N;
— the energies resulting from impact depend on the lift component where the impact can occur; if not
otherwise specified the resulting force is assumed to be 1 000 N.
With the exception of the items listed below, a mechanical device built according to good practice and
the requirements of the standard will not deteriorate to a point of creating hazard without the
possibility of detection.
The following mechanical failures are considered:
— breakage of the suspension;
— uncontrolled slipping of the ropes on the traction sheave;
— breakage and slackening of all linkage by auxiliary ropes, chains and belts;
— 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;
— failure of a component associated with the main drive elements and the traction sheave;
— ropes leaving the pulleys and, in case of change of inclination, leaving the rollers;
— blockage of the rope movement;
— blockage or derailment of the vehicle.
The possibility of the safety gear not setting, should the vehicle free fall from the lowest landing, before
the vehicle strikes the buffer(s) is considered acceptable.
When the speed of the vehicle is linked to the electrical frequency of the mains up to the moment of
application of the mechanical brake, the speed is assumed not to exceed 115 % of the rated speed or a
corresponding fractional speed.
Means of access are provided for the hoisting of heavy equipment.
To ensure the correct functioning of the equipment in the machinery space(s), i.e. taking into account
the heat dissipated by the equipment, the ambient temperature in the machine room is assumed to be
maintained between + 5 °C and + 40 °C.

Access ways to the working areas are adequately lit.
Minimum passageways required by building regulations 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 above Principles).
Where more than one person is working at the same time on a lift, an adequate means of
communication between these persons is ensured.
The fixing system of guards, which will be removed during maintenance and inspection, remains
attached to the guard or to the equipment when the guard is removed.
