at the latest by February 2010.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent

This European Standard 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 Annexes ZA and ZB, which are integral parts 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, Bulgaria, Cyprus, Czech
Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia,
Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain,

Introduction
#This European Standard is a type C standard as stated in EN ISO 12100.$
The object of this European Standard is to define rules for safeguarding persons and objects against the risk
of accidents associated with the operation of Mobile Elevating Work Platforms (MEWPs).
 This European Standard does not repeat all the general technical rules applicable to every electrical,
mechanical or structural component.
 The safety requirements of this European Standard have been drawn up on the basis that MEWPs are
periodically maintained according to manufacturers' instructions, working conditions, frequency of use
and national regulations.
It is also assumed that MEWPs are checked for function daily before start of work and are not put into
operation unless all required control- and safety-devices are available and in working order.
If a MEWP is seldom used, the checks may be made before start of work.
Furthermore it is assumed that persons on the work platform in case of power supply failure are not
incapacitated and can assist in the operation of the overriding emergency device.
 As far as possible this European Standard sets out only the requirements that materials and equipment
have to meet in the interest of safety, and it is assumed that persons operating MEWPs are adequately
trained.
 Where for clarity an example of a safety measure is given in the text, this shall not be considered as the
only possible solution. Any other solution leading to the same risk reduction is permissible if an equivalent
level of safety is achieved.
 As no satisfactory explanation could be found for the dynamic factors used for stability calculations in
previous national standards, the results of the tests carried out by the former CEN/TC98/WG1 to
determine a suitable factor and stability calculation method for MEWPs have been adopted. The test
method is described in annex B (informative) as a guide for manufacturers wishing to use higher or lower
operating speeds and to take advantage of developments in control systems.
Similarly, to avoid the unexplained inconsistencies in coefficients of utilisation for wire ropes found in other
standards for lifting devices, appropriate extracts of the widely accepted standard DIN 15020 have been taken
into 5.4.2 and annex C (normative) with a worked example in annex D (informative).
1 Scope
1.1 This European Standard specifies technical safety requirements and measures for all types and sizes of
Mobile Elevating Work Platform (MEWP) intended to move persons to working positions where they are
carrying out work from the work platform (WP) with the intention that persons are getting on and off the work
platform at one defined access position.
1.2 This European Standard is applicable to the structural design calculations and stability criteria,
construction, safety examinations and tests before MEWPs are first put into service. It identifies the hazards
arising from the use of MEWPs and describes methods for the elimination or reduction of these hazards.
It does not cover the hazards arising from:
a) operation by radio and other wire-less controls;
b) use in potentially explosive atmospheres;
c) electromagnetic incompatibility;
d) work on live electric systems;
e) use of compressed gases for load bearing components;
f) getting on and off the work platform at changing levels.
1.3 This European standard does not apply to:
a) permanently installed personnel lifting appliances serving defined levels (see e.g. EN 81-1:1998 and
EN 81-2:1998);
b) fire-fighting and fire rescue appliances (see e.g. prEN 1777:1994);
c) unguided work cages suspended from lifting appliances (see e.g. EN 1808:1999);
d) elevating operator position on rail dependent storage and retrieval equipment (see EN 528:1996);
e) tail lifts (see prEN 1756-1:1994 and prEN 1756-2:1997);
f) mast climbing work platforms (see EN 1495:1997);
g) fairground equipment;
h) lifting tables with a lifting height of less than 2 m (see EN 1570:1998);
i) builders hoists for persons and materials (see prEN 12159:1995);
j) aircraft ground support equipment (see e.g. prEN 1915-1 and 2:1995);
k) elevating operator positions on industrial trucks (see prEN 1726-2:1999).
1.4 Classification
MEWPs are divided into two main groups:
Group A: MEWPs where the vertical projection of the centre of gravity of the load is always inside the
tipping lines.
Group B: MEWPs where the vertical projection of the centre of gravity of the load may be outside the
tipping lines.
Relating to travelling, MEWPs are divided into three types:
type 1 Travelling is only allowed with the MEWP in its transport position;
type 2 Travelling
