The height of this discard division is located at the head park.

It has been shown, however, that in a very large number of applications of turntable ladders, especially those of the fire brigades, it applies by means of a bridge that goes through the extended ladder is formed, people zui / i Place of installation of the turntable ladder from an endangered to save ground-level place, from the place of erection of the turntable ladder, for example by a body of water or

fe shaft or a vapor trap or the like separated isto Even more frequent are use cases in which it applies

™ Guards from open or broken-in people to rescue from icy waters. In all of these applications it was when using the well-known turntable ladder constructions hitherto required that first the - ^ eiterpark pivoting in relation to the vertical Swivel axis of the turret extended in a horizontal position, the ladder climbed by a helper and by This a rope or a rope ladder or a similar auxiliary device is mounted on the Ijeiterspitze and to the Has been lowered into the ground or into the body of water. Due to the need to assemble a rope, a knitting

* ladder or a similar auxiliary device at the pus Great is especially valuable when the speed decides the success of a rescue Time is lost in the form of a fraction of the indicative time required to get the turntable ladder into its final To bring deployment position.

The invention is generally based on the novel and inventive problem, a drivable one To create turntable ladder, which avoids the disadvantages of the known turntable ladder constructions and without restriction your possible uses for quick return

management of places located at the level of the horizontal depositing position of the ladder park or above it People are also allowed to rescue people who are in places with no loss of guide time which are located below this storage position of the ladder parka. The aim is to save human lives without the use of further aids solely by means of the more or less lowered and extended ^ pus park may be possible.

This object is achieved by the invention in that at a Λ

mobile, in particular self-propelled and / or motor-driven, turntable ladder with one opposite the chassis the ladder park in the through the axis of rotation of the turret and the longitudinal axis of the vehicle determined by a plane from the horizontal Angle measured below - negative Y / angle - can be pivoted is.

The turntable ladder according to the invention solves the asked |

Task already when the ladder pool is lowered and extended accordingly. Special " when saving human life over existing fences or walls, it can be useful to use something known per se V / eise at the ulnar tip of one designed according to the invention Turntable ladder to have arranged a hanging access basket. The use of the turntable ladder after the Invention with such an access basket is easily possible. Such a hanging access basket offers the possibility of rescues not only over obstacles that result in a further lowering

oppose the ladder, but also separate people To save gaps, holes or the like, since the arranged on the correspondingly lowered ladder hanging access basket is then placed in this recess can be. On the other hand, the turntable ladder according to the invention also offers the possibility of being used in Association with a standing formed according to a proposal not belonging to the prior art and positively controlled with regard to the angle of inclination of its floor or step platform with respect to the axis of the emitter Access basket. A turntable ladder designed in this way according to the invention is particularly advantageous for rescuing people in distress in open or icy waters, as the standing access basket such a turntable ladder to just above the surface of the water can be brought, which is already during the pivoting and the extension of the ladder park a helper is located in this access basket and is available immediately upon reaching the scene of the accident stands to help people in need into the access basket.

A particularly expedient embodiment of the invention is characterized in that the eiterpark can be pivoted at least by such a negative angle with respect to the horizontal that, when the ladder is extended, the ladder tip can be reached and climbed from the ground. A further embodiment of the invention offers even more advantageous possible uses without or in conjunction with the use of a step-through cage arranged on the tip of the ladder, in which the - ^ eiterpark can be pivoted about such a negative angle with respect to the horizontal that, when the ladder is retracted, the ^ ous tip from Floor reachable from 109882/0 38A

and is mountable.

The device for pivoting the ladder park in the vertical direction, the so-called erecting device, can be designed in any known manner in the turntable ladder according to the invention such a rotary head having at least one hydraulic cylinder as a device for similar pivoting of the ladder set in the vertical direction, it has proved to be particularly suitable for achieving the ^ desired lowerability of the ladder set with simple and inexpensive means that the turret-side articulation of the or the other the raising (s ) is arranged at such a distance from the axis of rotation of the turret in the seal of the longitudinal axis of the vehicle and / or at such a distance from the lower boundary plane of the turret that the central axis (s) of the erecting cylinder (s) at the maximum lowered position of the ladder park against forms an angle in the range between a 30 ° to 50 ° with the lower delimitation plane of the turret or inserts it above the horizontal. I.

As an alternative or in addition to these measures, depending on the turntable ladder construction, further measures than proven expedient. A corresponding further embodiment of the invention is characterized in that the linkage on the support side of the erecting cylinder (s) at such a distance from the pivot axis for the relative pivoting of the mount and the turret arranged and / or the free length of the piston rod in the retracted state is selected so that the central
