Definitions

  • the invention relates to a rescue and / or work cage which is articulated at the upper end of a turntable ladder, an extendable mast or the like via a cage suspension.
  • the turntable ladder is in particular a mobile extendable fire ladder.
  • the hanging rescue cage protrudes approx. 1.3 m beyond the front end of the pushed ladder. This means that no space-saving arrangement at the tip of the conductor is possible. A rough vehicle length of the turntable ladder results when driving on the road.
  • the object of the invention is the basic elimination of the aforementioned disadvantages, in particular the creation of a rescue and / or work cage of the type mentioned, which is simple in construction and quick and reliable to use and is arranged in a space-saving manner in particular when not in use or while driving.
  • the essence of the invention is that the rescue and / or work cage can be pushed back as far as possible via the ladder set by means of a swivel mechanism and a suspension device of the rescue cage by a hydraulic motor, in order to significantly shorten the vehicle length of the aerial ladder for road traffic.
  • the swivel drive which is present in the rescue cage anyway, for controlling the swiveling movement of the rescue cage for the purpose of aligning the rescue cage floor horizontally, is hydraulically connected to the aforementioned hydraulic motor or hydraulic drive, which can preferably be a hydraulic cylinder, which is located in the middle of the ladder set.
  • the hydraulic drive moves the basket suspension in the longitudinal direction of the ladder and thus the articulation point of the rescue or work cage itself.
  • the swivel drive is basically able to move the rescue or work cage by 165 ° from the driving position to the maximum working position (+ 75 ° upright angle ) to pivot the ladder. Is the rescue or work cage horizontal, i.e. in the direction of the turntable ladder in the driving position, the hydraulic drive can be actuated and thus the basket suspension can be moved. This is preferably done by an electrical or hydraulic sequential circuit.
  • a key feature of the horizontal shift is the use of the free space from the top of the top part of the ladder to the diagonals of the part of the ladder pushed together.
  • the overall vehicle length can be shortened by approximately 1 m.
  • the rescue cage can have a hinge point in different rescue cage heights (hanging or standing version).
  • the articulation point of the rescue cage is preferably located approximately in the middle of the rescue cage.
  • the rescue or work cage (2) is articulated at the top or at the upper end of an extendable aerial ladder (20), in particular at the foremost or uppermost ladder part (14).
  • the rescue cage is articulated via a basket suspension (19) which is arranged on the uppermost ladder part (14) so as to be displaceable in the longitudinal direction of the turntable ladder (20).
  • the basket suspension comprises in particular laterally outer side supports (5) which are arranged obliquely with respect to the ladder and which determine the axis of rotation (10) of the rescue cage approximately in a central position.
  • the two identical side supports (5) are connected to each other by a cross member (9), which is additionally supported by an oblique strut (11). is stiffened.
  • a cross member (9) which is additionally supported by an oblique strut (11). is stiffened.
  • roller carriers (12) with rollers (8) which are guided left and right in the existing spar profile of the uppermost ladder part (14).
  • Upper additional rollers (8) are guided accordingly in the upper flange (16) of the uppermost ladder part (14).
  • the upper rollers (8) are connected at the upper end of oblique struts (17) of the basket suspension (19).
  • the latter oblique struts (17) have angular reinforcements (13) which are connected to the cross member (9) and, overall, ensure a connection-rigid basket suspension (19).
  • connection-rigid basket suspension (19) can be displaced overall by the upper and lower rollers (8) with respect to the uppermost ladder part (14) by means of a hydraulic drive or a hydraulic cylinder (4) which can be arranged centrally with respect to the width of the turntable ladder (20).
  • the hydraulic cylinder (4) is fed by a hydraulic unit (6), which is located in the rescue cage (2), which is already provided for the swivel drive (3) in the area of the axis of rotation (10) of the rescue cage, around the rescue cage (2) to pivot its driving position (B) into the 0 ° working position (A) and further into the 75 ° working position (C) (total swivel range: 165 °).
  • the basket is suspended in the middle according to the embodiment. This reduces the entry height with respect to the road level. If necessary, an extendable boarding ladder can be provided on the rescue cage (2) in order to achieve a normal boarding dimension that is approximately 60 cm or less.
  • the essential feature of the invention lies in the space utilization of the ladder set, precisely by the movable basket suspension, which can be moved by the dimension (z) (stroke or displacement path of the rescue basket).
  • Another feature relates to the change in position of the axis of rotation (10). For example, if dimension (y) is reduced and the basket is moved upwards, dimension (x) is also reduced, which further shortens the length of the vehicle. Dimension (y) is the height of the articulation point in the rescue cage, dimension (x) is the lateral depth of the articulation point.
  • the rear wall of the rescue cage (2) is closed at least up to half and the center of gravity of the rescue cage, including the people inside it, is located in the center of thrust of the ladder section designed as a U-shaped section in order to keep the torsional moment as low as possible.
  • An electrical or hydraulic sequential circuit is preferably provided, which ensures that the rescue cage (2) is only retracted when it has been brought into the driving position by means of the swivel drive (3). For the working position, this is done in the opposite direction.
  • a single hydraulic cylinder (4) arranged in the middle is sufficient for the displacement, which only has to shift the empty weight of the basket and the suspension in the described path.
  • the maximum displacement movement or the stroke (z) is determined by the overall construction of the ladder and the basket suspension (19), in particular by the cross member (9) of the basket suspension (19), which directly adjoins the diagonals (7) of the other ladder parts when the basket suspension is pushed back (Fig. 1).
