1.1 General
This European Standard specifies the technical requirements to minimize the hazards listed in Clause 4 which can arise during the commissioning, the operation and the maintenance of maintenance stairs and platforms when used as intended, including misuse reasonably foreseeable by the manufacturer, when carried out in accordance with the specifications given by the manufacturer or his authorized representative. It also takes into account some requirements recognized as essential by authorities, aircraft and ground support equipment (GSE) manufacturers as well as airlines and handling agencies.
These machines are designed to be used as aircraft ground support equipment with the intended use to serve aircraft in outdoor conditions on the apron. They may also be used indoors at hangars. The use of such equipment for operations not in conjunction with aircraft is not defined as intended use therein. Due to the good operational conditions on the apron, deviations from some clauses of EN 280 were deemed acceptable.
This European Standard applies to:
a) self-propelled fixed or adjustable maintenance stairs and elevating platforms;
b) towable maintenance stairs and platforms equipped with powered means, e.g. for height adjustment, stabilizers,
designed for aircraft maintenance purposes including access to the aircraft.
NOTE 1 Powered will be also understood as manual effort stored in springs or hydraulic accumulators, etc., the dangerous action of which can be produced or can continue after the manual effort has ceased or directly applied manual effort for lifting or lowering loads.
NOTE 2 Those clauses of this standard that can apply may also be used as a guideline for the design of towable maintenance stairs and platforms without powered means.
This European Standard does not apply to:
c) maintenance docks either fixed to the ground or moveable only for docking procedure.
d) ground support equipment specifically intended, built and equipped with a fluid system for aircraft de-icing and anti-icing (see EN 12312 6).
NOTE 3 This does not prevent aircraft de-icers meeting the requirements of EN 12312–6 from being used as a means of access for aircraft maintenance, e.g. windshield cleaning, etc.
e) mobile elevating work platforms (MEWP) used at the airports for purposes other than aircraft maintenance, e.g. buildings and facilities (see EN 280).
This standard does not establish requirements for hazards caused by noise and vibration.
NOTE 4 EN 1915–3 and EN 1915–4 provide the general GSE vibration and noise requirements.
This European Standard does not deal with hazards in respect to a standard automotive chassis and from other vehicles on the apron.
This part of EN 12312 is not applicable to maintenance stairs and platforms which are manufactured before the date of publication of this standard by CEN.
This part of EN 12312 when used in conjunction with EN 1915 1, EN 1915 2, EN 1915 3 and EN 1915 4 provides the requirements for maintenance stairs and platforms.
1.2 Classification
For the purposes of this European Standard, Mobile elevating work platforms (MEWPs) to be used for aircraft maintenance access are divided into two main groups A and B:
a) Group A: MEWPs where the vertical projection of the centre of the platform area is always inside the tipping lines.
NOTE See 5.2 hereafter for requirements applying to Group A MEWPs.
b) Group B: MEWPs where the vertical projection of the centre of the platform area may be outside the tipping lines.
NOTE See 5.3 hereafter for requirements applying to Group B MEWPs.
c) In addition, Group C consists of maintenance access stairs, where persons are not elevated by the machine but climb a flight of steps.
NOTE See 5.4 hereafter for requirements applying to Group C maintenance stairs.
Relating to travelling, MEWPs are divided into three types:
d) Type 1: Travelling is only allowed with the MEWP in its transport position;
