  • the whole turns Structure, aerial ladder, etc. with. Are the highest and the the lowest position of the two actuating cylinders is set lower rotary drive or its drive pinion non-positively connected to the vehicle frame or underframe, so that the lower slewing ring is blocked.
  • the Luffing drive of the luffing gear which over the assigned Inclination sensor for the vertical position of the vertical axis of the adjustable structure is controlled. More specifically the lowest one is a hydraulic one Adjusting cylinder of the luffing gear extended while the other hydraulic actuating cylinders at the highest position is retracted until the upper slewing ring is exactly horizontal is aligned. Accordingly aligned horizontally is then the upper adjustable structure, and it can this through the upper actuator of the upper slewing ring twisted exactly in the horizontal and for example a turntable ladder arranged thereon in a certain turntable and height position are driven.
  • the upper and lower rotary drive during the compensation process for Alignment of the vertical axis can be operated simultaneously and in opposite directions such that the structure does not rotate and only takes part in the seesaw movement.
  • a particularly simple construction of the alignment device results itself if slewing rings, actuators and / or actuating cylinders are essentially the same.
  • the invention uses only two of the same Standard slewing rings allow which of only two of the same Standard actuators or rotary drives must be driven.
  • the complicated oblique is advantageously eliminated Training of the intermediate slewing ring mentioned above and its actuator, especially the comparative complicated manufacture of the convex known drive pinions.
  • the arrangement consists of simple components and there is also a simple control and position control.
  • Another particularly advantageous development of the invention is characterized in that the lower slewing ring by means of a ball slewing ring in the form of a roller bearing is replaced and the latter instead of the lower rotary drive has a locking device through which the ball slewing ring with regard to the base can.
  • the luffing gear is first turned until the positioning cylinders are in the fall line.
  • the ladder support of the commercial vehicle serves as a counter-holding device for the assembly during the turning process of the luffing gear. If the actuating cylinders are in the fall line, the parking brake is applied. The ladder is then raised. After an upright angle of approx. 5 °, the luffing cylinders start to work and bring the vertical axis into line.
  • a level swivel block with an upper swivel head, rocker, roller bearing and parking brake with effect in the direction of the base frame has great advantages in addition to a simple overall structure.
  • DE-PS 20 36 559 is a rocker-like yoke linkage a mobile pull-out ladder, especially a fire ladder, known.
  • the known yoke linkage requires always one during the rotation on the inclined plane Readjust the ladder or the basket floor to the horizontal Level.
  • the alignment device according to FIG DE-A-22 65 165 is not the essence of the invention.
  • the fire engine illustrated in Figs. 1 and 2 includes a device (10) for the vertical alignment of the Vertical axis (9) one with a base (11) rotatable and inclinable structure (7) consisting of carriage and Turntable ladder (12).
