EN 12312-3:2003 (E)
Introduction
This European Standard specifies health and safety requirements, as well as some functional and performance
requirements, for conveyor belt vehicles intended for loading/unloading of individual items of baggage or cargo for
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 conveyor belt vehicles. 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 1070:1998.
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 conveyor belt vehicles when carried out in
accordance with the specifications given by the manufacturer or his authorised representative. It also takes into
account some requirements recognised as essential by authorities, aircraft and ground support equipment (GSE)
manufacturers as well as airlines and handling agencies.
This standard applies to:
self-propelled conveyor belt vehicles with or without driver's accommodation;
self-propelled conveyor belt vehicles equipped with a van body;
towed conveyor belt vehicles,
Intended to be used for manual loading/unloading of aircraft.
Examples of typical designs of conveyor belt vehicles are given in annex A.
This standard does not apply to pneumatic systems and to cableless remote controls.
This standard does not establish requirements for hazards caused by noise and vibration.
This Part of EN 12312 is not applicable to conveyor belt vehicles which are manufactured before the date of
publication of this standard by CEN.
2 Normative references
This European Standard incorporates by dated or undated reference, provisions from other publications. These
normative references are cited at the appropriate places in the text, and the publications are listed hereafter. For
dated references, subsequent amendments to or revisions of any of these publications apply to this European
Standard only when incorporated in it by amendment or revision. For undated references the latest edition of the
publication referred to applies (including amendments).

4 List of hazards
The list of risks and hazards (see annex B) is based on EN 1050:1996 and contains the hazards and hazardous
situations, as far as they are dealt with in this European Standard, identified by risk assessment as significant for
conveyor belt vehicles and which require action to eliminate or reduce risks. Not covered are risks and hazards due
to a standard automotive chassis, the traffic, maintenance and repair and general misuse.
5 Safety requirements and/or measures
5.1 General requirements
5.1.1 Self-propelled vehicles with a driver's accommodation shall be fitted with restraint straps.
5.1.2 Conveyor belt vehicles shall conform to the relevant requirements of EN 1915-1:2001, unless otherwise
specified in this standard. They shall also conform to the specific requirements of this standard.
5.1.3 Strength calculations shall be carried out in accordance with EN 1915-2:2001.
5.1.4 Stability calculations shall be carried out according to EN 1915-2:2001. Special attention shall be paid to
travel conditions.
5.1.5 The electrical system of battery powered conveyor belt vehicles shall conform to EN 1175-1:1998, with the
exception of standard automotive chassis.
5.1.6 The boom shall protrude front and rear.
NOTE Therefore the overall length of the conveyor belt vehicle is defined by the overall boom length.
5.1.7 The conveyor belt vehicle shall be capable of servicing any aircraft sill height, for which it is designed, with
the opposite end not higher than 760 mm from the intended loading level(s).
5.1.8 Where adjustment of elevation of both ends of the boom is provided it shall be possible to adjust the ends
independent from each other.
5.1.9 It shall be possible to gain access to servicing points, e.g. dipstick, fluid replenishment points, without
operating the power source; even with the boom in the lowest position.
5.1.10 All sharp edges or corners resulting from the manufacturing process shall be chamfered or rounded with a
minimum radius of 1 mm.
5.1.11 Where a sprung front axle is used, the suspension shall be restricted so as to limit vertical movement at the
front end of the boom, when the conveyor belt vehicle is being driven, e.g. by using shock absorbers.
5.1.12 Where power operated stabilizers are provided, it shall be possible to retract the stabilizers in the event of
primary power loss by auxiliary means, e.g. hand pump.
5.1.13 Structural parts or stabilizers of pedestrian controlled self-propelled conveyor belt vehicles shall not
protrude from the overall length within the operating range of the tiller.
5.1.14 Where lights for the illumination of working areas are fitted, their design shall conform to EN 1837:1999.
The minimum electrical power of the lamp shall be 25 W.
5.1.15 Self-propelled vehicles with driver's cabin shall have an alternative means of exit in the event of an
emergency.
