Rough-terrain trucks - Safety requirements and verification - Part 2: Slewing variable-reach trucks
This European Standard specifies the general safety requirements of slewing variable-reach rough-terrain trucks (here-after referred to as trucks), consisting of a lower chassis with a slewing upper structure equipped with a telescopic lifting means (pivoted boom), on which a load handling device (e.g. carriage and fork arms) is typically fitted.
Fork arms are covered by this European Standard and considered to be parts of the truck.
This European Standard deals with all significant hazards, hazardous situations and events relevant to the trucks when they are used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer (see Annex A) with the exception of hazards listed in 1.3 and 1.4.
This European Standard does not apply to:
- variable-reach rough terrain trucks covered by prEN 1459-1 (non-slewing);
- industrial variable-reach trucks covered by prEN ISO 3691 2;
- lorry-mounted variable-reach trucks;
- variable reach trucks fitted with tilting or elevating operator position;
- mobile cranes covered by EN 13000;
- machines designed primarily for earth moving, such as loaders and dozers, even if their buckets and blades are replaced with forks (see EN 474 series);
- trucks designed primarily with variable length load suspension elements (e.g., chain, ropes) from which the load may swing freely in all directions;
- trucks designed primarily for container handling;
- trucks on tracks;
- attachments (prEN 1459-5).
This European Standard does not address hazards linked to:
- hybrid power systems;
- gas power system;
- trucks equipped with gasoline engine;
- battery power system;
- tractor specific devices (e.g. PTO).
This European Standard does not address hazards which may occur when:
a) handling suspended loads which may swing freely (additional requirements are given in prEN 1459-4);
b) using trucks on public roads;
c) operating in potentially explosive atmospheres;
d) operating underground;
e) when towing trailers;
f) fitted with a personnel work platform (additional requirements are given in EN 1459-3).
Geländegängige Stapler - Sicherheitstechnische Anforderungen und Verifizierung - Teil 2: Schwenkbare Stapler mit veränderlicher Reichweite
Diese Europäische Norm legt die allgemeinen sicherheitstechnischen Anforderungen an geländegängige schwenkbare Stapler mit veränderlicher Reichweite (im Folgenden als Stapler bezeichnet) fest, bestehend aus einem abgesenkten Fahrgestell mit schwenkbarem oberen Aufbau mit einem Teleskophubarm als Hebevorrichtung (Schwenkhubarm), an der in der Regel ein Lastaufnahmemittel (z. B. Trägerplatte und Gabelzinken) angebracht ist.
Gabelzinken werden in dieser Europäischen Norm behandelt und gelten als Teile des Staplers.
Diese Europäische Norm behandelt alle signifikanten Gefährdungen, Gefährdungssituationen und Gefährdungsereignisse, die auf Stapler zutreffen, wenn sie bestimmungsgemäß und unter Bedingungen von durch den Hersteller vernünftigerweise vorhersehbaren Fehlanwendungen verwendet werden (siehe Anhang A).
Chariots tout-terrain - Prescriptions de sécurité et vérification - Partie 2 : Chariots à portée variable rotatifs
La présente Norme européenne spécifie les prescriptions générales de sécurité des chariots tout-terrain à portée variable rotatifs (ci-après désignés « chariots »), constitués d’un châssis inférieur avec une structure supérieure rotative équipée de moyens de levage télescopiques (flèche rotative), sur lesquels un dispositif porte-charge est habituellement monté (par exemple, un tablier porte-équipement et des bras de fourche).
Les bras de fourche sont couverts par la présente Norme européenne et considérés comme des parties du chariot.
La présente Norme européenne traite de tous les phénomènes dangereux significatifs, des situations et évènements dangereux pertinents pour les chariots lorsqu'ils sont utilisés comme prévu et dans les conditions de mauvaise utilisation qui sont raisonnablement prévisibles par le fabricant (voir Annexe A).
La présente Norme européenne ne s'applique pas :

b) lors de l'utilisation des chariots sur les voies publiques ;
c) lors d’une utilisation en atmosphères explosibles ;
d) lors de travaux souterrains ;
e) lors de la traction de remorques ;
f) lorsque les chariots sont équipés d’une plates-forme de personnel/travail (des prescriptions supplémentaires sont données dans l’EN 1459-3).
