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 container/pallet transfer transporters 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 handling agencies. This European Standard applies to self-propelled container/pallet transfer transporters, with a seated driver. Examples of typical transfer transporters are shown in Annex A. This European Standard does not apply to: - loading equipment with a height adjustment capability in excess of 150 mm; - transporter-loaders (single platform loader with transporter capability, see EN 12312 9); - roller-bed transport platforms mounted on unmodified commercial road chassis. 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 is not dealing with hazards in respect to a standard automotive chassis and the traffic on the apron. This Part of EN 12312 is not applicable to GSE which are manufactured before the date of publication by CEN of this European Standard. NOTE Certain measurements have been given in imperial units (in parentheses) following the metric measurements since the containers/pallets to be handled are based mainly on the imperial system. This part of EN 12312 is intended to be used in conjunction with EN 1915-1, EN 1915-2, EN 1915-3 (for vehicles) and EN 1915-4.
