  • laterally acting on the boom loads that can represent the traglastbesky criterion in an operating position of the boom can be better absorbed.
  • a disadvantage of this mobile telescopic crane that the guy supports represent a significant additional weight. The guy supports must therefore be transported separately on a truck to the site and mounted there on the boom. This is associated with a considerable cost and time.

  • the invention has for its object to provide a mobile telescopic crane, which allows a simple way to increase the load.
  • a mobile telescopic crane with the features of claim 1.
  • the area moment of inertia of the boom is significantly increased.
  • the area moment of inertia which is a measure of the bending stiffness, results, according to Steiner's theorem, from the own shares of the sub-cantilevers and their Steiner shares.
  • the boom Due to the rigid connecting elements that connect the sub-boom sections of the sub-boom to boom sections, the boom is extremely rigid, so that the cross-sectional area remains substantially flat under load of the boom, whereby the Steiner shares in the calculation of the area moment of inertia substantially with their theoretical Values, possibly reduced by reduction factors, can be applied.

  • the boom according to the invention Due to the significant increase in the area moment of inertia or the area moments of inertia of the boom according to the invention can be completely different dimensions than conventional boom, so that in comparison to a conventional boom with guy supports a corresponding increase in the load with a lower additional weight can be achieved.
  • the sub-arms are constructed of telescoping part-boom sections in the longitudinal direction, the boom can be brought from a transport position to an operating position with little effort.

  • the inventive mobile telescopic crane thus enables a simple way to increase the load.
  • the boom according to the invention can be dimensioned such that in comparison to a conventional boom with guy supports again a significant increase in the load can be achieved.
  • the boom according to the invention also has a considerable weight, so that the mobile telescopic crane with the boom according to the invention may no longer be able to participate fully in public traffic. Individual sub-cantilevers or a group of sub-cantilevers or the entire boom must then be transported separately to the site and mounted there. In the described Dimensioning of the boom according to the invention is thus the advantage in increasing the load.

  • the sub-arms are fixable to each other in a displaced operating position. This is done in particular by means of mechanical locking units.
  • the mechanical locking units are arranged, for example, on the connecting elements.
  • a mobile telescopic crane according to claim 8 ensures in the extended operating position of the boom high rigidity by the mechanical locking of each adjacent Auslagerabroughe, since the built-up of the sub-boom sections sub-arms are extremely rigid by the lock.

Every locking bolt must be performed only by two associated locking holes of the adjacent sub-boom sections to lock them mechanically to each other. The distance to be traversed for locking the respective locking bolt is low. Because the respective locking bolt only has to be guided by two associated locking bores, a comparatively low accuracy in the alignment of the respective locking bolt is required. Preferably, exactly two locking bolts are provided, which are arranged opposite to each other and can be actuated in opposite directions.
  • a mobile telescopic crane according to claim 14 ensures a high rigidity against bending forces acting perpendicular to the rocker plane. If the at least two sub-arms with the greatest distance to the rocker plane would be arranged on an underside of the jib facing the undercarriage, so that the width of the jib would decrease from its underside to its upper side, then the at least two lower-part jibs would Both due to acting in the rocker bending forces and due to acting perpendicular to the rocker bending forces are charged to pressure. Such a construction of the boom would lead to an undesirable load limitation of the boom or the mobile telescopic crane due to the double pressure load according to the Euler kinks.
  • the at least two sub-arms are arranged with the greatest distance to the rocker plane on the side facing away from the undercarriage or upper side of the boom, so acting in the rocker plane bending forces substantially to a tensile load of at least two upper part boom lead, whereas perpendicular to the rocker plane acting bending forces to a pressure load of the upper one Lead partial boom.
  • the pressure load on the furthest to the rocker plane spaced sub-arms can thus be significantly reduced.
  • the area moment of inertia is thus increased on the one hand in accordance with the invention, but on the other hand avoided a double pressure load.
  • the width of the boom can be dimensioned at the top in wide areas as needed. If the jib has exactly four sub-jibs which are arranged in a triangular shape, then a lower sub-jib facing the undercarriage is arranged in the jockey plane and three upper sub-jibs facing away from the undercarriage are arranged at a distance from the rocking plane or in the rocker plane, so that the width of the boom increases from the lower boom to the upper boom and the upper side, respectively.
  • the jib has exactly four partial jibs which are arranged trapezoidally, then the width of the jib increases, starting from two lower jib sections facing the undercarriage, to two upper sub-jibs facing away from the undercarriage.
  • the lower part boom thus have a smaller distance to the rocker plane, as the upper part boom. Since the pressure load due to acting perpendicular to the rocker plane bending forces decreases with the distance to the rocker plane, the bending stiffness is optimized with respect to perpendicular to the rocker plane acting bending forces even with a boom with trapezoidally arranged sub-arms.
  • the width of the boom increases from a lower, in the rocker plane arranged sub-boom to two spaced apart from the rocker plane arranged upper part arms, whereby the described advantages are achieved.
  • the arranged in the rocker plane, upper part boom is not loaded due to both acting in the rocker bending forces and due to acting perpendicular to the rocker bending forces on pressure. A reduction of the width of the boom, starting from the spaced apart to the rocker plane, upper part boom to the arranged in the rocker plane, upper part boom is thus not disadvantageous.
  • a mobile telescopic crane according to claim 15 ensures a high rigidity of the boom relative to the rocker acting bending forces.
  • By the end-side locking adjacent sub-boom sections laterally acting bending forces are derived directly into the entire boom and absorbed by this. This is ensured, in particular, by the fact that the respective at least one locking bolt is fastened or displaceably mounted directly on the associated or adjacent connecting element.
  • a mobile telescopic crane according to claim 16 ensures a high flexural rigidity against bending forces acting in the rocker plane. Due to its partial cross-sectional area, the at least one partial boom facing the undercarriage can absorb high bending forces acting in the seesaw plane. The flexural rigidity of the boom is thus correspondingly high.
