High rise aerial appliances for fire service use - Turntable ladders with sequential movements - Safety and performance requirements and test methods
EN 14044 specifies the safety and performance requirements and test methods applicable to turntable ladders with sequential movements of classes 18, 24, 30 and > 30 to 56, as defined in 3.13, under the control of fire-fighters and intended for fire fighting and rescuing people. Turntable ladder vehicles comprise a chassis, bodywork and a powered extending structure unit in the form of a ladder with or without a rescue cage. Turntable ladder vehicles covered by this European Standard have a self-propelled chassis, the motor of which supplies the power necessary for the operation of the ladder. They do not permit operational movements to be made simultaneously. This European Standard deals with the technical safety requirements to minimize the hazards listed in Clause 4 which can arise during commissioning, operational use, routine checking and maintenance of turntable ladders when carried out in accordance with the specifications given by the manufacturer or the manufacturer's authorized representative. This European Standard deals with the use of turntable ladder vehicles within an ambient temperature range from -15 °C to +35 °C and with a wind velocity on the ladder set ≤ 12,5 m/s. Additional measures can be necessary for use outside this range. Special designs for use under special climatic conditions should be agreed between the manufacturer and the purchaser. Any additional requirements are outside the scope of the standard. This European Standard does not deal with the design of a standard automotive chassis with regard to hazards resulting from or due to use as a road vehicle. This European Standard is not applicable to turntable ladder vehicles with sequential movements which are manufactured before the date of publication of this European Standard by CEN.
Hubrettungsfahrzeuge für die Feuerwehr - Drehleitern mit aufeinander folgenden (sequenziellen) Bewegungen (Halbautomatik-Drehleitern) - Sicherheits- und Leistungsanforderungen sowie Prüfverfahren
1.1 Diese Europäische Norm legt die Sicherheits- und Leistungsanforderungen sowie Prüfverfahren für Drehleitern mit aufeinander folgenden (sequenziellen) Bewegungen (Halbautomatik-Drehleitern) der Klassen 18, 24 und 30, entsprechend der Definition in 3.13 fest; diese gelten für die Anwendung der Dreh-leiter durch die Feuerwehr für die Brandbekämpfung und die Rettung von Menschen. ANMERKUNG Diese Europäische Norm ist für die Anwendung in Verbindung mit EN 1846-1, EN 1846-2 und EN 1846-3 vorgesehen. Drehleiterfahrzeuge bestehen aus einem Fahrgestell, dem Aufbau und einem kraftbetätigten Ausleger in Form einer Leiter mit oder ohne Korb. Die durch diese Europäische Norm abgedeckten Drehleiterfahrzeuge verfügen über ein Fahrgestell mit Eigen-antrieb, dessen Motor die für das Betreiben der Leiter erforderliche Energie bereitstellt. Sie lassen nicht die gleichzeitige Ausführung von Einsatzbewegungen zu. 1.2 Diese Europäische Norm behandelt die technischen Anforderungen zur Minimierung der in Abschnitt 4 aufgeführten Gefährdungen, die während der Inbetriebnahme, des Betriebes sowie der Routineüberprüfungen und Wartung von Drehleitern auftreten können, wenn diese entsprechend den Festlegungen des Herstellers oder seines Bevollmächtigten durchgeführt werden. Behandelt werden ebenfalls die Leistungsanforderungen. 1.3 Diese Europäische Norm behandelt den Einsatz von Drehleiterfahrzeugen in einem Temperaturbereich von −15 °C bis +35 °C und mit einer auf den Drehleitersatz wirkenden Windlast von ≤ 12,5 m/s. Zusätzliche Maßnahmen können für einen Einsatz außerhalb dieses Bereiches erforderlich sein (zwischen Hersteller und Anwender zu vereinbaren). ANMERKUNG Sonderausführungen für den Einsatz unter besonderen klimatischen Bedingungen sollten zwischen dem Hersteller und dem Kunden vereinbart werden. 1.4 Diese Europäische Norm behandelt weder die Gefährdungen des Standard-Fahrgestells noch die Gefährdungen infolge des Einsatzes als Straßenfahrzeug.

1.1 La présente Norme européenne spécifie les prescriptions de sécurité et de performances, et les méthodes
d'essais applicables aux échelles pivotantes à mouvements séquentiels de classes 18, 24 et 30, telles que définies
au 3.13, manoeuvrées par les sapeurs-pompiers et prévues pour la lutte contre l'incendie et le sauvetage de
personnes.
NOTE La présente Norme européenne est destinée à être utilisée en association avec les normes EN 1846-1, EN 1846-2
et EN 1846-3.
Les véhicules à échelle pivotante comprennent un châssis, une carrosserie et une structure extensible motorisée,
sous la forme d'une échelle avec ou sans panier.
Les véhicules à échelle pivotante couverts par la présente Norme européenne ont un châssis automoteur dont le
moteur assure la puissance requise pour faire fonctionner l'échelle. Ils ne permettent pas de faire simultanément
des mouvements opérationnels.
1.2 La présente Norme européenne traite des prescriptions techniques de sécurité destinées à minimiser les
phénomènes dangereux énumérés à l'Article 4, pouvant survenir pendant la mise en service, le fonctionnement, la
vérification et la maintenance de routine des échelles pivotantes, effectués conformément aux spécifications
données par le fabricant ou son mandataire.
Elle traite également des prescriptions de performance.
1.3 La présente Norme européenne traite de l'utilisation des véhicules à échelle pivotante dans une plage de
température de – 15 °C à + 35 °C et avec une vitesse de vent sur la structure extensible ≤ 12,5 m/s. Des
dispositions supplémentaires peuvent être nécessaires pour un usage en dehors de cette plage (à négocier entre
le fabricant et l'utilisateur).
NOTE Il convient que les conceptions particulières relatives à un usage dans des conditions climatiques spéciales soient
convenues entre le fabricant et l'acheteur.

EN 14044:2014 (E) 8 1 Scope 1.1 This European Standard specifies the safety and performance requirements and test methods applicable to turntable ladders with sequential movements of classes 18, 24, 30 and > 30 to 56, as defined in 3.13, under the control of fire-fighters and intended for fire fighting and rescuing people. NOTE This European Standard is intended to be used in conjunction with EN 1846–1, EN 1846–2 and EN 1846–3. Turntable ladder vehicles comprise a chassis, bodywork and a powered extending structure unit in the form of a ladder with or without a rescue cage. Turntable ladder vehicles covered by this European Standard have a self-propelled chassis, the motor of which supplies the power necessary for the operation of the ladder. They do not permit operational movements to be made simultaneously. 1.2 This European Standard deals with the technical safety requirements to minimize the hazards listed in Clause 4 which can arise during commissioning, operational use, routine checking and maintenance of turntable ladders when carried out in accordance with the specifications given by the manufacturer or the manufacturer's authorized representative. 1.3 This European Standard deals with the use of turntable ladder vehicles within an ambient temperature range from −15 °C to +35 °C and with a wind velocity on the ladder set ≤ 12,5 m/s. Additional measures can be necessary for use outside this range. Special designs for use under special climatic conditions should be agreed between the manufacturer and the purchaser. Any additional requirements are outside the scope of the standard. 1.4 This European Standard does not deal with the design of a standard automotive chassis with regard to hazards resulting from or due to use as a road vehicle. 1.5 This European Standard is not applicable to turntable ladder vehicles with sequential movements which are manufactured before the date of publication of this European Standard by CEN. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
