  • To increase the load and reduce the deflection of the the extended main boom is on the main boom of the main boom
  • Base box removable guy stand arranged with an almost length-fixed guying with the foot area of the main boom on the one hand and with a further guying, which is usually adjustable in length, with the head or collar of one of the inner telescopic sections on the other connected.
  • This stiffening arrangement is applicable to the basic device alone, but also in connection with the arrangement of one formed from lattice tower parts rigid or luffing jib.
  • the object of the invention is to provide a telescopic crane, the lateral Deformation of the boom, especially in the steep position, is significantly less than at known telescopic cranes.
  • At least one is on the boom opposite Rocker plane inclined guy support arranged with a substantially in Longitudinal direction of the boom extending clamping means is connected, the The angle of the guy support is selected so that it acts on the boom lateral or partial load is completely absorbed by the guying becomes.
  • the inclination of the guy support can be transverse to the longitudinal direction or in Longitudinal direction or superimposed transversely to and in the longitudinal direction of the boom.
  • both Guy braces are provided, usually the angular inclination of both Guy supports are the same. But depending on the direction of the boom attacking forces may also be different.
  • the foot ends of both guy supports can be connected to the top of the boom at a common location, but also offset from each other.
  • the foot end of at least one guy support in the transition area between Top side or respective side wall connected to the boom.
  • there is also the possibility to cross the foot end of at least one guy support To arrange the longitudinal axis of the boom and overhanging this beam.
  • the proposed arrangement has the advantage that depending on the angular position Guy supports: the amount of guy force that acts in the lateral direction, can be changed continuously or continuously.
  • the two guy supports in parallel are the same Effect in the sense of a superlift operation like the well-known guy stand.
  • ⁇ 90 ° to> 0 ° for the two guy supports will be the effective one Clamping force divided into a superlift operation component and a component lateral guying.
  • the two guy supports In the second extreme position, i.e. H. in the horizontal position, the two guy supports only reinforce in both directions.
  • the respective free head end of the guy support is over a first clamping device optionally with the undercarriage, the uppercarriage, the foot area of the boom, the fixed or separately guided counterweight or the floor in the direction Foot end of the boom and a further clamping device with a selected one Place the boom connected in the direction of the boom head.
  • the one you want Angular position of the guy supports can be gradual or continuous Swiveling the guy supports can be adjusted. That is also one asymmetrical angle adjustment possible. This means that when attacking Lateral force only on one side the respective guy support more towards the side Guy is inclined while the second guy support is in a central position remains.
  • the clamping devices can be used as a rope or as a rod be trained.
  • the clamping device or the clamping device can be with and without Preload can be arranged. In the case of a preload and one
  • the clamping device can be readjusted with a clamping device together. This is preferably a winch or a piston-cylinder unit. But also the angle adjustment and / or the change in length of the guy support can in Can be used as a tensioning device.
  • the jigs are either on the guy supports, on the boom, on the superstructure or undercarriage or on Counterweight can be arranged.
  • the guy supports on the main boom are preferably in the area of the Basic box arranged, especially in the front area between the Linkage of the luffing cylinder and the front bearing.
  • For continuous Adjustment of the guy supports is preferably every guy support with one on the piston-cylinder unit supported on the basic box.
  • the equipment of the telescopic boom can be supplemented with the arrangement a rigid or luffing jib made of lattice boom parts. Also on the proposed lateral bracing can be attached to these cantilever elements become.
  • Side guying can be used particularly effectively if the Crane with a measuring device to record the lateral deformation of the boom is provided. If the deformation exceeds a specified permissible value the tensioning device connected to the guying is activated and the guying tightened.
  • the degree of lateral deformation can be direct or indirect Crane sizes can be determined. For example, these are the rope tension, the rope length and rope elongation. But also in terms of the forces acting on the boom the side wind, the sun and the boom prevailing temperatures can make a statement about the degree of lateral Deformation can be made.
  • FIGS. 1 a-c the possible arrangement of one another is shown as a basic sketch the guy support inclined.
  • the guy support 2 is preferably on the top 3 of a symbolically shown here Cantilever element 1 arranged.
  • This boom element 1 can be a basic box or a shot from a main boom of a telescopic crane or that Lattice mast element of a rigid or luffing jib.
  • the in Cantilever element 1 center axis 4 is also ideally the luffing plane of the boom.
  • the guy support 2 is in relation to the luffing plane inclined at an angle ⁇ > 0.
  • the dashed representation of the guy support 2 ' should make it clear that the guy support 2 can also be tilted towards the other side.
  • the free end 5 of the guy support 2 is preferably with a clamping means 6.7 connected to a rope.
  • the connection of the clamping means 6, 7 is not shown here a fixed location on the boom or a clamping device such as Piston cylinder unit or winch. Tensioning the clamping means 6,7 can can also be reached without a clamping device. Firstly, in such a way that the clamping device 6.7 can be arranged at a smaller or larger angle ⁇ and then the Guy support 2 is further inclined. Alternatively, it is also possible to use the guy support 2 telescopic and a degree of tension by changing the length to reach.
  • FIG 2 is also a schematic diagram of the arrangement of two guy supports 2.1, 2.2 shown.
  • the peculiarity of this arrangement is that both Guy supports 2.1,2.2 with only a single foot end 8 on the top 3 of the Cantilever element 1 are arranged.
  • the respective angle of inclination ⁇ 1, ⁇ 2 can be the same or different.
