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 and 30, as defined in 3.13, under the control of firefighters 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 cage. Turntable ladder vehicles covered by this European Standard have a self-propelled chassis, the motor of which supplies the power required 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 requirements to minimise the hazards listed in Clause 4 which can arise during the commissioning, the operational use and the routine checking and maintenance of turntable ladders when carried out in accordance with the specifications given by the manufacturer or the manufacturer authorised representative. It also deals with performance requirements. 1.3 This European Standard deals with the use of turntable ladder vehicles within a 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 (to be negotiated between the manufacturer and the user). NOTE Special designs for use under special climatic conditions should be by arrangement between the manufacturer and the purchaser. 1.4 This European Standard is not dealing with the hazards of the standard automotive chassis or due to use as a road vehicle. 1.5 This European Standard is not applicable to turntable ladders vehicles with sequential movements which are manufactured before the date of publication of this European Standard by CEN.
