Aircraft ground support equipment - Specific requirements - Part 8: Maintenance stairs and platforms
This document specifies the technical requirements to minimise the hazards listed in Clause 4 which can arise during the commissioning, operation and maintenance of maintenance stairs and platforms when carried out in accordance with the specifications given by the manufacturer or his authorised representative. It also takes into account some performance requirements recognised as essential by authorities, aircraft and ground support equipment (GSE) manufacturers as well as airlines and maintenance and handling agencies.
This document applies to:
- self-propelled maintenance stairs and platforms;
- 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 (Examples see Annex A).
NOTE 1 Powered should 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 document that can apply may also be used as a guideline for the design of towable maintenance stairs and platforms without powered means.
This document does not apply to:
- maintenance docks either fixed to the ground or moveable only for docking procedure.
This document does not establish requirements for noise and vibration.
Noise and vibration are dealt with respectively in EN 1915-4 and EN 1915-3.
This document 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.
Luftfahrt-Bodengeräte - Besondere Anforderungen - Teil 8: Wartungstreppen und -bühnen
Diese Europäische Norm legt die technischen Anforderungen zur Minimierung der in Abschnitt 4 aufgelisteten
Gefährdungen fest, die bei Inbetriebnahme, Betrieb und Wartung von Wartungstreppen und -bühnen auftreten
können, wenn diese in Übereinstimmung mit den Anweisungen des Herstellers oder seines Beauftragten
ausgeführt werden. Sie berücksichtigt auch einige Funktions- und Gestaltungsanforderungen, die von
offiziellen Stellen, Luftfahrzeug- und Bodengeräteherstellern sowie Luftverkehrs- und Wartungs-/Überholungs-
gesellschaften als wesentlich erachtet wurden.
Diese Europäische Norm gilt für:
- selbstfahrende Wartungstreppen und -bühnen;
- schleppbare Wartungstreppen und -bühnen, die mit kraftbetriebenen Einrichtungen, z. B. zur Höhen-
anpassung, Abstützung, ausgerüstet sind,
und die für Wartungsarbeiten an Luftfahrzeugen einschließlich des Zugangs zum Luftfahrzeug bestimmt sind
(Beispiele siehe Anhang A).
ANMERKUNG 1 Kraftbetrieben sollte auch verstanden werden als in Federn gespeicherte menschliche Arbeitskraft
oder hydraulische Akkumulatoren o. Ä. deren gefährliche Wirkung nicht zwangsläufig mit Einstellung der menschlichen
Tätigkeit beendet ist, oder unmittelbar angewandte menschliche Arbeitskraft zum Heben oder Senken von Lasten.
ANMERKUNG 2 Zutreffende Abschnitte dieser Europäischen Norm können auch als Grundlage für die Gestaltung von
schleppbaren Treppen ohne kraftbetätigte Einrichtungen dienen.
Diese Europäische Norm gilt nicht für:

Introduction
This European Standard specifies health and safety requirements, as well as some functional and performance
requirements for maintenance stairs and platforms including a built-in source of power (see Clause 1, Scope)
intended for maintenance purposes on all aircraft types commonly in service in civil air transport.
The minimum essential criteria are considered to be of primary importance in providing safe, serviceable,
economical and practical maintenance stairs and platforms. Deviations from the recommended criteria should
occur only after careful consideration, extensive testing, risk assessment and thorough service evaluation have
shown alternative methods or conditions to be satisfactory.
This European Standard is a Type C standard as stated in EN ISO 12100:2003.
The machinery concerned and the extent to which hazards, hazardous situations and events are covered are
indicated in the scope of this document.
When provisions of this type C standard 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.
1 Scope
This European Standard specifies the technical requirements to minimise the hazards listed in Clause 4 which can
arise during the commissioning, operation and maintenance of maintenance stairs and platforms when carried out
in accordance with the specifications given by the manufacturer or his authorised representative. It also takes into
account some performance requirements recognised as essential by authorities, aircraft and ground support
equipment (GSE) manufacturers as well as airlines and maintenance and handling agencies.
This European Standard applies to:
self-propelled maintenance stairs and platforms;
towable maintenance stairs and platforms equipped with powered means, e.g. for height adjustment, stabi-
lizers,
designed for aircraft maintenance purposes including access to the aircraft (Examples see Annex A).
NOTE 1 Powered should be also understood as manual effort stored in springs or hydraulic accumulators, etc., the danger-
ous 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 European 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:
maintenance docks either fixed to the ground or moveable only for docking procedure.
This European Standard does not establish requirements for noise and vibration.
Noise and vibration are dealt with respectively in EN 1915-4 and EN 1915-3.
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.
