High rise aerial appliances for fire and rescue service use - Turntable ladders with sequential movements - Safety and performance requirements and test methods

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.

1.1   Diese Europäische Norm legt die Sicherheits- und Leistungsanforderungen sowie Prüfverfahren für Drehleitern mit aufeinander folgenden (sequenziellen) Bewegungen der Klassen 18, 24, 30 und > 30 bis 56, entsprechend der Definition in 3.13 fest; diese gelten für die Anwendung der Drehleiter 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.
Drehleitern bestehen aus einem Fahrgestell, dem Podium und einem kraftbetätigten Ausleger in Form einer Leiter mit oder ohne Rettungskorb.
Die durch diese Europäische Norm abgedeckten Drehleitern verfügen über ein Fahrgestell mit Eigen¬antrieb, dessen Motor die für das Betreiben der Leiter notwendige Energie bereitstellt. Sie lassen nicht die gleichzeitige Ausführung von Einsatzbewegungen zu.
1.2   Diese Europäische Norm behandelt die technischen Sicherheitsanforderungen zur Minimierung der in Abschnitt 4 aufgeführten Gefährdungen, die während der Inbetriebnahme, des Einsatzes sowie der Routine-überprüfungen und Wartung von Drehleitern auftreten können, wenn diese entsprechend den Festlegungen des Herstellers oder des Bevollmächtigten des Herstellers durchgeführt werden.
1.3   Diese Europäische Norm behandelt den Einsatz von Drehleitern in einem Bereich der Umgebungstemperatur von 15 °C bis 35 °C und mit einer auf den Leitersatz wirkenden Windlast von  12,5 m/s. Zusätzliche Maßnahmen können für einen Einsatz außerhalb dieses Bereiches erforderlich sein.
Sonderausführungen für den Einsatz unter besonderen klimatischen Bedingungen sollten zwischen dem Hersteller und dem Kunden vereinbart werden. Zusätzliche Anforderungen liegen außerhalb des Anwendungsbereichs der Norm.
1.4   Diese Europäische Norm behandelt nicht die Ausführung eines Standard-Fahrgestells im Hinblick auf die Gefährdungen infolge oder wegen des Einsatzes als ein Straßenfahrzeug.
1.5   Diese Europäische Norm gilt nicht für Drehleitern mit aufeinander folgenden (sequenziellen) Bewegungen, die vor dem Veröffentlichungsdatum dieser Europäischen Norm durch CEN hergestellt wurden.
