DIN EN 14044:2014-04

The standard has been prepared by Working Group CEN/TC 192/WG 4 "High rise aerial appliances" (secretariat: DIN, Germany) at European Technical Committee CEN/TC 192 "Fire and Rescue Service Equipment" (secretariat: BSI, Great Britain). Collaboration of DIN at the European Committee for Standardization (CEN) for the field of responsibility of Working Group CEN/TC 192/WG 4 "High rise aerial appliances" is performed through Working Committee NA 031-04-08 AA of the same name. Human rescue is the primary task of the turntable ladders at the place of action. The rescued persons can be safely moved downwards in the cage of turntable ladders. Furthermore, the turntable ladders are used for example during elevated fire attack from the outside, for lighting, ventilation and partly as cranes. Turntable ladders with combined movements are the most commonly used high rise aerial appliances for fire and rescue service use in Germany. In addition to turntable ladders with sequential movements in accordance with this standard there are still fully automatic turntable ladders in accordance with DIN EN 14043. The turntable ladders with sequential movements can only perform one movement, fully automatic turntable ladders can perform all movements simultaneously. The amendment of the published standard EN 14044:2005+A1:2009 has become necessary to adapt the technical content to the state of the art and to promote future developments. The standard loads to be given when ordering turntable ladders in Germany are listed in the national Annex NA. Working Committee NA 031-04-08 AA "Hubrettungsfahrzeuge" recommends the use of a three-person crew (1 driver + 2 persons; in German Truppbesatzung 1/2), and - to ensure operability even in narrow areas - a minimum load carrying capacity of two persons at a jacking width of 4,5 m or lower so that the nominal rescue projections specified for that type of ladder can be reached. Greater nominal projections and jacking widths are permitted at the responsibility of the manufacturer. Users of this European Standard should note that the specifications of the German Länder building regulations, as well as DIN 14090, apply as regards the space necessary to ensure fire brigade access to premises; these specifications will have an effect on the design, for example, dimensions, gross laden mass and axle loads. Specifications regarding periodic inspections of firefighting vehicles are given in GUV-G 9102.
