Definitions

  • the invention relates to a rescue and / or work cage, or the like at the upper end of a pivotable aerial ladder, an extendable mast. is articulated via a hanger.
  • the object of the invention is to provide a rescue and / or work basket of the type mentioned, which is simple in construction and can be operated with very little adjustment energy.
  • the essence of the invention is the arrangement of at least one torsion bar parallel to the articulation axis of the rescue and / or work cage, the torsion bar being fixed between the basket and the basket hanger.
  • two essentially identical torsion bars are provided in an essentially mirror-image arrangement with respect to the width of the basket.
  • the torsion bar (s) are able to absorb the weight of the rescue cage and part of the payload resulting from the weight of the cage + payload times the lever arm to the axis of rotation) in the working area of the ladder -15 ° to + 75 °) and thereby the external energy supply for to significantly reduce or save the necessary adjustment mechanism of the basket.
  • the kinetic energy from the basket driving position is pivoted over the ladder set) into the working position. This movement is usually done without a payload. This results in an energy surplus for the adjustment mechanism, which is now used to pretension the torsion bars.
  • a single hydraulic unit is sufficient to pivot the basket due to the low need for adjustment energy.
  • An additional hydraulic unit including the associated power supply line from the gearbox to the tip of the conductor can therefore be omitted (cable drum or hydraulic line).
  • the rescue and / or work cage can be arranged in a space-saving manner at the tip of the ladder by folding over the ladder set.
  • Another advantage is the good use of space in the rescue cage, for example the arrangement of a stretcher, the storage of which can be easily attached while the stretcher is optimally pivotable.
  • the rescue cage (2) is attached to the basket hanger (3) of the uppermost ladder part of the turntable ladder (8) via a swivel gear (4) and two torsion bars (5).
  • the two torsion bars (5) which are essentially of the same mirror-image design, are located outside the articulation axis (1) of the rescue cage (2).
  • Both swivel gears (4) are driven by a common hydraulic drive (7) in order to carry out the swiveling movement of the basket with respect to the turntable ladder (8).
  • the basket (2) is pivoted from its aforementioned non-use position (A) into the 0 ° working position (B) with the aid of the single hydraulic drive (7) in connection with the two swivel gears (4), the two torsion bars (5) are prestressed .
  • the center distance between the articulation axis (1) of the rescue cage (2) and the pivot point of the torsion bars (5) results in a small torsion bar adjustment angle.
  • the swivel bearing (6) fixed to the basket (2) transmits the spring force of the torsion bars (5) on both sides, since the torsion bars (5) are firmly clamped to the hanger (3).
  • the aforementioned swiveling movement between the non-use position (A) and the 0 ° working position (B) of the basket takes place without a payload.
  • the pretension of the torsion bars (5) is designed so that the load torque of the basket in the 0 ° working position (B) and part of the payload for the adjustment mechanism become approximately zero.
  • the restoring torque of the torsion bars (5) remains approximately constant, since the lever arm of the pivot bearing decreases with respect to the articulation axis (1) of the basket (2) while increasing the restoring force of the Torsion bars (5).
  • the pivot bearing (6) describes a narrower circular arc and moves axially on the torsion bar.
  • the basket (2) reaches a total swivel range of approx. 165 °.
  • the articulation axis can also be located higher or lower with respect to the basket. With a lower pivot axis, the so-called standing basket design results. Access to the vehicle is then made more difficult, but the overall vehicle length is reduced because the basket can be folded over the ladder set.
  • the invention can be used in many ways, for example on elevators or telescopic work platforms.
