Foreword
This document (prEN 81-7:2009) has been prepared by Technical Committee CEN/TC 10 “Lifts, escalators and
moving walks”, the secretariat of which is held by AFNOR.
This document is currently submitted to the CEN Enquiry.
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 EC Directive.
For relationship with EC Directive, see informative Annex ZA, which is an integral part of this document.
This standard covers the necessary additional precautions by replacing the relevant existing text of EN 81-1:1998
or adding new clauses as indicated.
Introduction
Clauses 0.1 - 0.3.15 in EN 81-1:1998 apply except that 0.3.10 and 0.3.15 shall read as follows:
0.3.10 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:
a) breakage and slackening of all linkage by auxiliary ropes,
b) failure of one of the mechanical components for the electromechanical brake which take part in the application
of the braking action on the drum or disk,
c) failure of a component associated with the main drive elements and the pinion gear.
0.3.15 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.

0.3.16 The following clause is added:

The fixing system of guards, which have to be removed during maintenance and inspection, remains attached to
the guard or to the equipment, when the guard is removed.

0.3.17 The following clause is added:
Access ways to the working areas are adequately lit (see 0.2.5 in EN 81-1:1998).
0.3.18 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).
0.3.19 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.
1 Scope
1.1 This standard specifies the safety rules for the construction and installation of permanently installed new rack
and pinion lifts with the drive unit attached to the car serving defined landing levels, having a car designed for the
transportation of persons or persons and goods supported by rack and pinion and moving between guide rails
inclined not more than 15° to the vertical. The maximum rated speed is 2 m/s.
1.2 In addition to the requirements of this standard supplementary requirements shall be considered in special
cases (potentially explosive atmosphere, extreme climate conditions, seismic conditions, transporting dangerous
goods, etc.)
1.3 This standard does not cover:
a) lifts with drives other than those stated in 1.1;
b) installation of rack and pinion lifts in existing buildings to the extent that space does not permit;
c) important modifications (see annex E) to a lift installed before this standard is brought into application, and
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;
°
e) installations where the inclination of the guide rails to the vertical exceeds 15 ;
f) safety during transport, installation, repairs, and dismantling of lifts;
g) lifts with rated speed ≤ 0,15 m/s.
NOTE Exclusion mentioned under g) bases on the Machinery Directive 2006/42/EC
Noise and vibrations are not dealt within this standard because these are not relevant to the safe use of the lift.
However, this standard may usefully be taken as a basis.
1.4 This standard does not specify the additional requirements necessary for the use of lifts in case of fire.
2 Normative references
This European Standard incorporates by dated or undated reference, provisions from other publications. These
normative references are cited at the appropriate places in the text and the publications are listed hereafter. For
dated references, subsequent amendments to or revisions of any of these publications apply to this European
Standard only when incorporated in it by amendment or revision. For undated references the latest edition of the
publication referred to applies (including amendments).
The normative references of EN 81-1:1998 apply with the following additions:
EN 81-1:1998, Safety rules for the construction and installation of lifts - Part 1: Electric lifts.

building whose internal structure is completely renewed is considered as a new building.

4 List of significant hazards
This clause contains all the significant hazards, hazardous situations and events, as far as they are dealt with in
this standard, identified by risk assessment as significant for this type of machinery and which require action to
eliminate or reduce the risk. The significant hazards are based upon EN ISO 14121-1:2007. Also shown are the
