Overview

prEN 280-1 (CEN draft) specifies safety requirements and verification measures for Mobile Elevating Work Platforms (MEWPs). The standard addresses design calculations, stability criteria, construction, safety features, and required examinations and tests for MEWPs intended to move persons to working positions. The scope clarifies that users are expected to get on and off the work platform only at access positions at ground level or on the chassis. Developed by CEN/TC 98, this document will supersede EN 280-1:2022 when adopted.

Key Topics

The standard organizes safety and technical requirements into clear, actionable sections. Important topics include:

• Design and structural calculations: required approaches for load determination, stability calculations and structural verification.
• Stability criteria: methods to assess overturning risks and dynamic factors affecting MEWP stability.
• Chassis and stabilizers: requirements for base structure and stabilizing systems that affect safe deployment.
• Extending structures and drive systems: safety measures for booms and lifts, including wire rope, chain, lead screw and rack-and-pinion drives.
• Work platform requirements: levelling, fall-off protection, access, anchorage and vibration considerations.
• Controls and safety functions: control positions, emergency stop, prevention of unexpected movement, remote/cableless controls and overriding.
• Electrical and hydraulic systems: requirements for reliable operation and load-holding functions.
• Verification, examinations and tests: type tests, manufacturing checks and pre-market tests to confirm compliance.
• Information for use and marking: documentation, records and marking requirements for safe operation and traceability.

The standard also contains informative annexes on hazards, wind use guidance, dynamic factors, calculation methods (including wire rope systems), and other normative annexes for control systems and dimensions.

Applications

prEN 280-1 is practical for stakeholders who design, manufacture, certify, procure or operate MEWPs:

• Designers and engineers can use the stability and structural guidance to validate calculations and material choices.
• Manufacturers can align production checks and type tests with the standard’s verification procedures.
• Test labs and certification bodies will reference the examinations and tests section for type approval and compliance testing.
• Fleet managers and safety officers can use the information-for-use and marking requirements to improve operator guidance, training and maintenance regimes.

Compliance with prEN 280-1 reduces operational risk, improves machine reliability and supports consistent safety practice across markets in CEN member states.

Introduction
This document is a type C standard as stated in EN ISO 12100:2010.
This document is a type-C standard as stated in EN ISO 12100.
This document is of relevance, in particular, for the following stakeholder groups representing the market
players with regard to machinery safety:
— machine manufacturers (small, medium and large enterprises);
— health and safety bodies (regulators, accident prevention organizations, market surveillance etc.).
Others can be affected by the level of machinery safety achieved with the means of the document by the
above-mentioned stakeholder groups:
— machine users/employers (small, medium and large enterprises);
— machine users/employees (e.g. trade unions, organizations for people with special needs);
— service providers, e.g. for maintenance (small, medium and large enterprises);
— consumers (in case of machinery intended for use by consumers).
The above-mentioned stakeholder groups have been given the possibility to participate at the drafting
process of this document.
The machinery concerned and the extent to which hazards, hazardous situations or hazardous events are
covered are indicated in the Scope of this document.
When requirements of this type-C standard are different from those which are stated in type-A or type-B
standards, the requirements of this type-C standard take precedence over the requirements of the other
standards for machines that have been designed and built according to the requirements of this type-C
standard.”
The object of this document 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 document does not repeat all the general technical rules applicable to every electrical,
mechanical or structural component.
— The safety requirements of this document 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 assumed that MEWPs are used only by qualified and trained operators.
It is also assumed that MEWPs are checked for function daily by the operator before start of work and
are not put into operation unless all required control and safety functions are available and in working
order.
It is assumed, if a MEWP is seldom used, the checks are carried out before start of work.
— As far as possible this document 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 C (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 utilization for wire ropes found in
other standards for lifting devices, appropriate extracts of the widely accepted standard DIN 15020-1
have been taken into 4.5.2 and Annex D (normative) with a worked example in Annex E (informative).
1 Scope
1.1 This document 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 such as a variable reach truck which are equipped with
work platforms as interchangeable equipment are regarded as MEWPs.
1.2 This document 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) work from the platform on external live electric systems;
c) use of compressed gases for load bearing components;
d) getting on and off the work platform at changing levels;
e) specific applications (e.g. railway, ships) covered by National or local regulations.
1.3 This document does not apply to:
a) machinery serving fixed landings (see e.g. EN 81-20:2020 and EN 81-50:2020, EN 12159:2024);
b) fire-fighting and fire rescue appliances (see e.g. EN 1777:2010);
c) unguided work cages suspended from lifting appliances (see e.g. EN 1808:2015);
d) elevating operator position on rail dependent storage and retrieval equipment (see
EN 528:2021+A1:2022);
e) tail lifts (see EN 1756-1:2021 and EN 1756-2:2004+A1:2009);
f) mast climbing work platforms (see EN 1495:1997+A2:2009);
g) fairground equipment;
h) lifting tables (see EN 1570-1:2024 and EN 1570-2:2016);
i) aircraft ground support equipment (see e.g. EN 1915-1:2023 and EN 1915-2:2001+A1:2009);
j) elevating operator positions on industrial trucks (see EN ISO 3691-3:2016).
1.4 Classification of MEWPS:
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 indicated in the information for use 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 position, or no travelling of the
MEWP is possible due to only being moveable (3.1.3) by design;
2) Type 2: Travelling with lifted work platform is controlled from a point of control at the chassis;
3) Type 3: Travelling with lifted work platform is controlled from a point of control at the work
platform.
NOTE Type 2 and type 3 can be combined.
