Foreword
This document (EN 81-2:1998/A2:2004) has been prepared by Technical Committee CEN/TC 10 “Lifts, escalators
and moving walks”, the secretariat of which is held by AFNOR.
This Amendment to the European Standard EN 81-2:1998 shall be given the status of a national standard, either
by publication of an identical text or by endorsement, at the latest by April 2005, and conflicting national standards
shall be withdrawn at the latest by April 2005.
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.
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following
countries are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech Republic, Denmark,
Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta,
Netherlands, Norway, Poland, Portugal, Slovakia, Slovenia, Spain, Sweden, Switzerland and the United Kingdom.
EN 81-2:1998 requires special machine and pulley rooms. Modern technology shows that machines and
associated parts can be located in the well, on the car or in cabinets. To ensure the safety of normal operation,
maintenance and inspection provisions are necessary which are not yet described in this standard.
This amendment covers the necessary additional precautions by replacing the relevant existing text of EN 81-
2:1998 or adding new clauses as indicated.

0.3.15 The text of this clause is replaced by the following:
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 machinery space(s) is assumed to be maintained
between + 5 °C and + 40 °C.
0.3.18 The following clause is added:
Access ways to the working areas are adequately lit (see 0.2.5).
0.3.19 The following clause is added:
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 0.2.5).
0.3.20 The following clause is added:
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 whole of clause 6 is replaced by the following:
6 Machinery and pulley spaces
6.1 General provisions
Machinery and pulleys shall be located in machinery and pulley spaces. These spaces and the associated working
areas shall be accessible. Provisions shall be made to allow access to the spaces only to authorised persons
(maintenance, inspection and rescue). The spaces and the associated working areas shall be suitably protected
against environmental influences to be taken into consideration and provisions made for suitable areas for
maintenance/inspection work and emergency operation. See 0.2.2, 0.2.5 and 0.3.3.
See Annex L.
If the machinery space is not adjacent to the well, the hydraulic piping and the electric wiring connecting the
machine room with the lift well shall be installed in a duct or trough, specially reserved for this purpose (see
12.3.1.2).
6.2 Access
6.2.1 The access way adjacent to any door/trap giving access to machinery and pulley spaces shall be:
a) capable of being properly lit by a permanent electric light fixture(s);
b) easy to use in complete safety in all circumstances without necessitating entry into private premises.
6.2.2 A safe access for persons to machinery and pulley spaces shall be provided. For preference this should be
effected entirely by way of stairs. If it is not possible to install stairs, ladders satisfying the following requirements
shall be used:
6
---------------------- Page: 7 ----------------------
EN 81-2:1998/A2:2004 (E)

1) depth, measured from the external surface of the enclosures, at least 0,70 m;
2) width, the greater of the following values: 0,50 m or the full width of the cabinet or panel;
7
---------------------- Page: 8 ----------------------
EN 81-2:1998/A2:2004 (E)

where this is necessary and, if need be, manual emergency operation (12.9).
6.3.3.2 The clear height for movement shall not be less than 1,80 m.
The access ways to the clear spaces mentioned in 6.3.3.1 shall have a width of at least 0,50 m. This value may be
reduced to 0,40 m where there are no moving parts.
This clear height for movement is taken to the underside of the structural roof beams and measured from the floor
of the access area.
6.3.3.3 There shall be a clear vertical distance of at least 0,30 m above the rotating parts of the machine.
6.3.3.4 When the machine room floor comprises a number of levels differing by more than 0,50 m, stairways

All trap doors, when they are closed, shall be able to support two persons, each counting for 1000 N on an area of
0,20 m x 0,20 m at any position, without permanent deformation.
Trap doors shall not open downwards, unless they are linked to retractable ladders. Hinges, if any, shall be of a
type which cannot be unhooked.
When a trap door is in the open position, precautions shall be taken to prevent the fall of persons (e.g. a guardrail).
6.3.4.3 Doors or trap doors shall be provided with a key operated lock, capable of being opened without a key
from inside the room.
Trap doors used only for access of material may be locked from the inside only.
6.3.5 Other openings
The dimension of holes in the slab and room floor shall be reduced to a minimum for their purpose.
With the aim of removing the danger of objects falling through openings situated above the well, including those for
electric cables, ferrules shall be used, which project at least 50 mm above the slab or finished floor.
6.3.6 Ventilation
The machine rooms shall be suitably ventilated. Should the well be ventilated through the machine room, this has
to be taken into account. Stale air from other parts of the building shall not be extracted directly into the machine
room. It shall be such that the motors, and equipment, as well as electric cables, etc., are protected as far as it is
reasonably practicable from dust, harmful fumes and humidity.
6.3.7 Lighting and socket outlets
