1.1   This European Standard specifies safety requirements and measures for all types and sizes of Mobile Elevating Work Platform (MEWP, see 3.1) 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 only at access positions at ground level or on the chassis.
NOTE   Machines designed for the handling of goods which are equipped with work platforms as interchangeable equipment are regarded as MEWPs.
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)   use in potentially explosive atmospheres;
b)   electromagnetic incompatibility;
c)   work from the platform on external live electric systems;
d)   use of compressed gases for load bearing components;
e)   getting on and off the work platform at changing levels;
f)   specific applications (e.g. railway, ships) covered by National or local regulations.

Introduction
This standard is a type C standard as stated in EN ISO 12100:2010.
The machinery concerned and the extent to which hazards, hazardous situations and hazardous events are
covered are indicated in the scope of this document.
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 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 emergency lowering.
 As far as possible this European Standard sets out only the requirements that materials and equipment
need 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 does not need to 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/TC 98/WG 1 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 15020-1 have been
taken into 5.5.2 and Annex C (normative) with a worked example in Annex D (informative).

1 Scope
1.1 This European Standard specifies safety requirements and measures for all types and sizes of Mobile
Elevating Work Platform (MEWP, see 3.1) 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 only at access positions at ground level or on the chassis.
NOTE Machines designed for the handling of goods which are equipped with work platforms as interchangeable
equipment are regarded as MEWPs.
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) use in potentially explosive atmospheres;
b) electromagnetic incompatibility;
c) work from the platform on external live electric systems;
d) use of compressed gases for load bearing components;
e) getting on and off the work platform at changing levels;
f) specific applications (e.g. railway, ships) covered by National or local regulations.
1.3 This European Standard does not apply to:
a) machinery serving fixed landings (see e.g. EN 81-1 and EN 81-2, EN 12159);
b) fire-fighting and fire rescue appliances (see e.g. EN 1777);
c) unguided work cages suspended from lifting appliances (see e.g. EN 1808);
d) elevating operator position on rail dependent storage and retrieval equipment (see EN 528);
e) tail lifts (see EN 1756-1 and EN 1756-2);
f) mast climbing work platforms (see EN 1495);
g) fairground equipment;
h) lifting tables (see EN 1570-1);
i) aircraft ground support equipment (see e.g. EN 1915-1 and EN 1915-2);
j) elevating operator positions on industrial trucks (see EN 1726-2).
1.4 Classification:
MEWPs are divided into two main groups:
a) Group A: MEWPs where the vertical projection of the centre of the area of the platform in all platform
configurations at the maximum chassis inclination specified by the manufacturer is always
inside the tipping lines.
b) Group B: All other MEWPs.
Relating to travelling, MEWPs are divided into three types:
1) Type 1: Travelling is only allowed with the MEWP in its transport configuration;
2) Type 2: Travelling with raised work platform is controlled from a point of control at the chassis;
3) Type 3: Travelling with raised work platform is controlled from a point of control at the work
platform.
NOTE Type 2 and type 3 can be combined.

5 Safety requirements and/or measures
5.1 General
5.1.1 Machinery shall comply with the safety requirements and/or protective measures of this clause. In
addition, the machine shall be designed according to the principles of EN ISO 12100:2010 for relevant but not
significant hazards, which are not dealt with by this document.
5.1.2 Totally manually operated MEWPs having a height of the floor of the work platform above ground
level not exceeding 5 m (see 7.2.17) are exempted from all safety requirements which cannot be met without
power supply.
5.2 Structural and stability calculations
5.2.1 General
It is the manufacturer's responsibility:
a) for structural calculations, to evaluate the individual loads and forces in their positions, directions and
combinations producing the most unfavourable stresses in the components, and
b) for stability calculations, to identify the various positions of the MEWP and combinations of loads and
forces creating together conditions of minimum stability.
5.2.2 Loads and forces
The following loads and forces shall be taken into account:
a) rated load (see 5.2.3.1);
b) structural loads (see 5.2.3.2);
c) wind loads (see 5.2.3.3);
d) manual forces (see 5.2.3.4);
e) special loads and forces (see 5.2.3.5).
5.2.3 Determination of loads and forces
5.2.3.1 Rated load
The rated load m is:
m=n⋅m +m (1)
p e
where
m is 80 kg (mass of a person)
p
m is ≥ 40 kg (minimum mass of tools and material)
e
n is the permitted number of persons on the work platform
The mass of each person is assumed to act as a point load on the work platform and any platform extension
at a horizontal distance of 0,1 m from the upper inside edge of the top rail. The distance between the point
loads shall be 0,5 m (see Figure 3 as an example).
The mass of equipment is assumed to act as an evenly distributed load on 25 % of the floor of the work
platform. If the resulting pressure exceeds 3 kN/m the figure of 25 % may be increased to a figure giving a
pressure of 3 kN/m (see Figure 4 as an example).
All these loads are assumed to be located in the positions giving the most severe results.
The above rated load refers to the maximum people and materials loads that can be placed on the deck
including any extension. Lower rated loads can be specified for extension(s) and under these circumstances
the load distributions specified in 6.1.4.2.1, 6.1.4.2.2 and 6.1.4.3 will need to be taken into account.

Figure 3 — Rated load – persons Figure 4 — Rated load – equipment

5.2.3.2 Structural loads
The masses of the components of the MEWP when they are not moving shall be taken to be static structural
loads.
The masses of the components of the MEWP when they are moving shall be taken to be dynamic structural
loads.
5.2.3.3 Wind loads
5.2.3.3.1 All MEWPs used out-of-doors are regarded as being affected by wind at a pressure of 100 N/m ,
equivalent to a wind speed of 12,5 m/s (Beaufort Scale 6).
Wind forces are assumed to act horizontally at the centre of area of the parts of the MEWP and persons and
equipment on the work platform and shall be taken to be dynamic forces.
This does not apply to MEWPs intended for indoor use only (see 7.2.7).
5.2.3.3.2 Shape factors applied to areas exposed to wind:
a) L-, U-, T-, I-sections: 1,6;
b) box sections: 1,4;
c) large flat areas: 1,2;
d) circular sections, according to size: 0,8/1,2;
e) persons directly exposed: 1,0.
If additional information is needed, especially concerning shielded structural areas, see ISO 4302. For
shielded persons see 5.2.3.3.3.4.
5.2.3.3.3 Area of persons on a work platform exposed to wind:
5.2.3.3.3.1 The full area of one person shall be 0,7 m (0,4 m average width × 1,75 m height) with the
centre of area 1,0 m above the work platform floor.
5.2.3.3.3.2 The exposed area of one person standing on a work platform behind an imperforate section
of fencing 1,1 m high shall be 0,35 m with the centre of area 1,45 m above the work platform floor.
5.2.3.3.3.3 The number of persons directly exposed to the wind shall be calculated as:
a) the length of the side of the work platform exposed to the wind, rounded to the nearest 0,5 m, and divided
by 0,5 m, or
b) the number of persons allowed on the work platform if less than the number calculated in a).
5.2.3.3.3.4 If the number of persons allowed on the work platform is greater than in 5.2.3.3.3.3 a) a
shape factor of 0,6 shall be applied to the extra number of persons.
5.2.3.3.4 The wind force on exposed tools and materials on the work platform shall be calculated as 3 % of
their mass, acting horizontally at a height of 0,5 m above the work platform floor.
5.2.3.4 Manual force
The minimum value for the manual force M shall be taken as 200 N for MEWPs designed to carry only one
person and 400 N
