Definitions

  • the invention relates to a mobile crane with another Superstructure articulated telescopic boom, which is connected to this by a and the rocker arm articulated to the superstructure can be rocked with one on the back of the telescopic boom in the upper area of his articulated shotgun, which by a Pressure fluid piston-cylinder unit is erectable and with a winch over which one goes from the top of the guy stand to the Headpiece or collar of an inner telescopic shot in progress Guy rope can be tensioned.
  • From DE-31 13 763 C2 is a mobile crane with a guyed Telescopic boom known, in which the guy rope exciting Winch and the fixed point of the guy rope on opposite Sides of the telescopic boom approximately in the guy stand are located with the pivoting axis connecting pivot.
  • the guy stand is anchored to the telescopic boom by ropes, that from the outer ends of the guy stand to the base of the articulation shot of the telescopic boom.
  • the Bracing of this known telescopic boom is proportionate elaborate, as this is not only due to the winch tensionable guy rope, but also by the fixed installed ropes that cannot be changed in length can be clamped via hydraulic cylinders. Will continue in this known mobile crane the guy rope through the winch depending on the length of the boom and / or the load and / or the boom angle automatically controls what is associated with an additional effort.
  • a mobile crane known from EP-0 334 187 A1 of the type specified at the beginning Art has a simple guyed telescopic boom than the guy stand by a hydraulic cylinder is held, in addition to its function as a holding cylinder serves as an erecting cylinder.
  • this known mobile crane are the winch and the fixed point of the guy rope on opposite Sides of the telescopic boom in the area of the Swivel axis arranged and the guying of the telescopic boom takes place only via the winch.
  • This well-known mobile crane too is still relatively expensive because of the guiding of the guy rope.
  • the object of the invention is therefore to provide a mobile crane of the beginning specified type with a simple guyed telescopic boom to accomplish.
  • this task is performed on a mobile crane solved type in that the guy stand by a rope or linkage of a predetermined length the uppercarriage, the base or the articulation axis of the articulation shot is braced and that the winch in the area of the top of the guy stand is arranged.
  • the guy stand erecting pressure medium piston-cylinder unit only very to be weakly trained, since they have no supporting or supporting function Has.
  • a pressure medium piston-cylinder unit could also be another device for erecting the guy stand be provided. After erecting the guy stand forms this - with the rope or linkage and the lower section of the articulated shot an essentially rigid triangle for the guy rope.
  • the winch that tightens the guy rope is arranged at the top of the guy blocks, so that a guy of the telescopic boom can be done directly without that the guy rope is guided over pulleys.
  • the Winch is provided with a ratchet mechanism that the applied Tension of the guy rope is maintained.
  • the jack lock provided with an automatically operated unlocking device his.
  • Guy rope through the winch according to the angle of the link and the extended state of the telescopes with constant force is braced. This type of guying can be done in a simpler way and reliable form.
  • Undercarriage 2 of a mobile crane 1 is in the usual way an uppercarriage 3 rotatably mounted on which the articulation section 4 of the telescopic boom is pivotally mounted about an axis 5.
  • the telescopes 6 which surround one another are from the articulation section 4 to 9 of the telescopic boom can be telescoped in the usual way.
  • the articulation section 4 is compared to the superstructure 3 by the hydraulic Rocker cylinder 10 rockable, the cylinder pivotable about the axle 11 articulated to the superstructure and its piston rod articulated in the middle area of the articulation section 4 is.
  • the guy stand 14 At the articulation section 4 is in its outer end region around the axis 13 pivoted the guy stand 14. In the merged Condition is the guy stand 14 folded onto the articulation section 4. To erect the guy bracket 14 is a pressure medium piston-cylinder unit 15 provided in the illustrated Way with one end on the guy bracket 14 and with her other End is hinged to the articulation section 4.
  • a winch 16 is fixed arranged at the outer end of the guy bracket 14.
  • the outer end of the guy bracket 14 is by a Rope or a foldable linkage 17 opposite the uppercarriage 3 guyed, the fixed point of the rope or guy rope 17 in the pivot axis 5 or the lower region of the Telescopic boom articulation piece 4 of the telescopic boom is located.
  • a guy rope 18 runs from the winch 16 to a deflection roller 19, at the head of the outermost telescopic shot or at one of the collars of the upper telescopic sections is attached. Of the pulley is the guy rope to the top of the guy stand 14 out where the fixed point of the guy winch 16 opposite located. The resultant of the guy rope 18 meets the resultant of the fixed in almost one point Guy 17.
  • the outer telescopic section carries 9 additionally a folding tip 20, through which a larger Boom length is attainable.
  • Each extension length of the telescopic boom has a specific one Rocking angle at which the guy rope with a fixed Force is preloaded when the crane is unloaded.
  • the guy rope 18 is stretched over the winch 16. For each The guy rope is pulled out with a constant force that is so great that in the unloaded Condition of the boom the guy rope 18 by a certain amount sags. This slack is only lost when the boom is loaded by a load to be lifted.
  • the Slack dimensioned so that the boom does not have a permissible Deflection can also.
  • the winch 16 is arranged in the upper region of the guy bracket 14 so that no additional pulley for the guy rope is required.
  • the guy rope runs from its fixed point in the area of the guy winch over the outer pulley and from this directly to the drum of the guy winch.
