EN 280:2001/A1:2004 (E)
Foreword
This document (EN 280:2001/A1:2004) has been prepared by the Technical Committee
CEN/TC 98 "Lifting platforms", the secretariat of which is held by DIN.
This Amendment to the European Standard EN 280:2001 shall be given the status of a national standard, either by
publication of an identical text or by endorsement, at the latest by January 2005, and conflicting national standards
shall be withdrawn at the latest January 2005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).
In the discussions about the French Appeal on prEN 280:1998 the proposal was made to refer to EN 954-1 and EN
ISO 13849-2:2003. This proposal was adopted by TC 98 and its WG 1 was given the task to prepare an
amendment. This decision was based on the following criteria:
The incorporation of this proposal into the draft standard would have required another CEN Enquiry into the whole
document with the consequence that the publication of EN 280 would have been further delayed. This delay was
not acceptable to the interested parties. The splitting between the formal vote of the modified EN 280 according to
the appeal and the elaboration of an amendment was regarded as an acceptable way to solve this problem.
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 United Kingdom.

2 Normative references
The following referenced documents are indispensable for the application of this document. For dated references,
only the edition cited applies. For undated references, the latest edition of the referenced document (including any
amendments) applies.

The following references were added:

design.
EN ISO 13849-2:2003, Safety of machinery — Safety related parts of control systems — Part 2: Validation.
CR 954-100:1999, Safety of machinery — Safety related parts of control systems — Part 100: Guide on the use
and application of EN 954-1:1996.
The following reference was deleted:
EN 60947-5-1:1997, Low-voltage switchgear and controlgear — Part 5-1: Control circuit devices and switching

4 List of hazards
In Table 1 the following references will be deleted:
in 10.1 the references 5.7.7 and 5.11.3
in 11.3 the reference 5.11.3 and 5.11.6
In Table 1 the following references will be changed:
in 10.1 the reference 5.7.9 into 5.7.8
in 10.3 the reference 5.7.8 into 5.7.7
in 11.3 the reference 5.7.9 into 5.7.7
in 13 the reference 5.7.10 into 5.7.9
in 21.1 the reference 5.7.10 into 5.7.9
5.3 Chassis and stabilisers
5.3.2
The text will be replaced by:
Every MEWP shall have a safety device in accordance with 5.11 (e.g. spirit level) to indicate whether the inclination
of the chassis is within the limits permitted by the manufacturer. This device shall be protected against damage and
accidental change of its setting.
For MEWPs with power driven stabilisers the indication shall be clearly visible from each control position of the
stabilisers.
On MEWPs of type 3 reaching the extreme limits of inclination this shall be indicated by an acoustic signal audible
at the work platform.

EN 280:2001/A1:2004 (E)
Verification: - by functional test
5.3.8 Use of stabilisers
This sub-clause will be restructured as follows:
5.3.8.1 MEWPs shall be fitted with a safety device in accordance with 5.11 which prevents the work platform
operating outside permitted positions unless the stabilisers are set in accordance with the operating instructions.
Verification: - by design check and functional test
5.3.8.2 MEWPs which are constructed for operation without stabilisers for a limited range of operation shall be
equipped with safety devices in accordance with 5.11 which prevent operation outside that limited range without
stabilisers.
Verification: - by design check and functional test
5.3.16
The text will be replaced by:
By the use of safety device(s) in accordance with 5.11 it shall not be possible to exceed the following travel speeds
with manned work platforms out of the transport position on MEWPs of types 2 and 3:
a) 1,5 m/s for vehicle mounted MEWPs when using the travelling controls inside the cab;
b) 3,0 m/s for rail mounted MEWPs;
c) 0,7 m/s for all other self-propelled MEWPs of types 2 and 3.
Verification: - by design check and functional test
5.4 Extending structure
5.4.1.3.1
As the non-mechanical stops are dealt with in 5.4.1.3.3 with reference to 5.11 the text will be replaced by:
To avoid overturning of the MEWP or exceeding the permissible stresses in the structure of the MEWP, the
permissible positions of the extending structure shall be limited automatically by mechanical stops (see 5.4.1.3.2)
or non-mechanical limiting devices (see 5.4.1.3.3).
5.4.2
The text will be replaced by:
When the extending structure needs to be extended or retracted in a specific sequence to avoid overloading and/or
overturning, this sequence shall be automatic. The automatic sequence shall be part of the position control (see
5.4.1.3) or moment sensing system (see 5.4.1.4).
Verification: - by design check and functional test
5.4.4
The text will be replaced by:
Trapping and shearing points between parts of the extending structure, the chassis and work platform shall be
avoided by providing guarding or safe clearances in accordance with EN 349.
5

---------------------- Page: 6 ----------------------

EN 280:2001/A1:2004 (E)
Trapping and shearing points need only be considered at those areas within reach of persons on the work platform
or standing adjacent to the MEWP at ground level, or at other points of access. For areas such as:
 turntables crossing stabilisers / chassis;
 resting points for extending structures in transport position;
 stabilisers moving into transport position
where neither safe clearance in accordance with EN 349 nor guarding is possible, warning notices shall be fitted
(see 7.2.13).
Instead of a rigid or flexible guard on MEWPs designed to pass through openings with a width of about 1,2 m and a
height of about 2 m the following solution is permitted:
The downward movement shall be automatically stopped by a safety device in accordance with 5.11 in a position,
where between the outer ends of the scissors the vertical distance is not less than 50 mm, so that crushing and
shearing of fingers cannot occur. Further downward movement shall only be possible after a suitable time delay,
giving the operator the opportunity to see, whether persons beside the MEWP could be injured, and a further
command of the operator.
Verification: - by measurement and visual examination
5.5 Extending structure drive systems
5.5.2.1a
The text will be replaced by:
a) a mechanical device operating by engaging with the extending structure. This safety device shall gradually
bring the work platform plus the rated load to a stop and hold it in the event of the wire rope drive system
failing. The average deceleration shall not exceed 1,0 g . The proper functioning of the device shall be
n
demonstrated by calculation and test(s). Any spring operating this device shall be a guided compression spring
with secured ends, or with wire diameter more than half the pitch in the operating condition, to limit the
sho
