Definitions

  • the invention relates to a mobile crane with a telescopic boom articulated on its superstructure, which can be luffed by a luffing cylinder articulated on this and the superstructure, with a guy stand articulated on the back of the telescopic boom in the upper region of its articulation section, which is supported by a pressure medium piston cylinder.
  • Unit is erectable, and with a winch, via which a guy rope running from the tip of the guy stand to the head piece or collar of an inner telescopic section can be tensioned.
  • a mobile crane with a guyed telescopic boom in which the winch tensioning the guy rope and the fixed point of the guy rope are located on opposite sides of the telescopic boom, approximately in the pivot axis connecting the guy frame with the articulated shot.
  • the guy stand is braced against the telescopic boom by ropes that run 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 relatively complex, since it is not only done by the guy rope that can be tensioned by the winch, but also by the permanently installed ropes that cannot be changed in length and that can be braced by hydraulic cylinders.
  • the guy rope through the winch automatically regulated depending on the length of the boom and / or the load and / or the boom angle, which is associated with additional effort.
  • a mobile crane of the type specified at the outset which is known from EP-0 334 178 A1 has a more easily braced telescopic boom in that the guy stand is held by a hydraulic cylinder which, in addition to its function as a holding cylinder, also serves as an erecting cylinder.
  • the winch and the fixed point of the guy rope are arranged on opposite sides of the telescopic boom in the region of its pivot axis and the telescopic boom is only braced via the winch.
  • This known mobile crane is also relatively expensive because of the guiding of the guy rope.
  • the object of the invention is therefore to provide a mobile crane of the type specified at the outset with a simple guyed telescopic boom.
  • this object is achieved in a mobile crane of the type specified in that the guy stand is anchored by means of a rope or a linkage of a predetermined length to the uppercarriage or the base or the articulated axis of the articulated shot and that the winch is arranged at the tip of the guy stand .
  • the pressure medium piston-cylinder unit erecting the guy stand need only be made very weak, since it has no supporting or supporting function.
  • a pressure medium-piston-cylinder unit another device for erecting the guy stand could also be provided. After erecting the guy stand this forms with the rope or linkage and the lower section of the articulation section an essentially rigid retaining triangle for the guy rope.
  • the winch tensioning the guy rope is arranged at the top of the guy stand, so that the telescopic boom can be guyed in a direct manner without the guy rope being guided over pulleys.
  • the winch is provided with a ratchet mechanism which maintains the tensioning force applied to the guy rope.
  • the ratchet lock can be provided with an automatically actuated unlocking device.
  • the guy rope is tensioned with constant force by the winch in accordance with the angle of the link piece and the extended state of the telescopes.
  • This type of bracing can be carried out in a simple and reliable form.
  • angles of the articulation piece belonging to each extension length are expediently stored in a list (bit map) so that they can be read out by the electronic control device during the automatic control of the operating state.
  • a certain tensioning force of the guy rope belongs to each extension state and thus the rocking angle of the articulation shot. This tensioning force is measured so that the guy rope sags to the required extent in the unloaded state of the crane.
  • a superstructure 3 is rotatably mounted in the usual manner, on which the articulation section 4 of the telescopic boom is pivotally mounted about an axis 5.
  • the telescoping arms 6 to 9 of the telescopic boom, which surround one another, can be telescoped out in the usual manner from the articulation section 4.
  • the articulation section 4 can be rocked in relation to the superstructure 3 by the hydraulic rocker cylinder 10, the cylinder of which is pivotally articulated about the axis 11 on the superstructure and the piston rod of which is articulated approximately in the middle region of the articulation section 4.
  • the guy bracket 14 On the articulation section 4, the guy bracket 14 is pivoted in its outer end region about the axis 13. In the folded state, the guy stand 14 is folded onto the articulation section 4. To erect the guy stand 14, a pressure medium piston-cylinder unit 15 is provided, which is articulated in the manner shown with one end to the guy stand 14 and with its other end to the articulation section 4.
  • a winch 16 is fixed.
  • the outer end of the guy bracket 14 is by a Rope or a foldable linkage 17 braced against the superstructure 3, the fixed point of the rope or guy linkage 17 being in the pivot axis 5 or the lower region of the telescopic boom link 4 of the telescopic boom.
  • a guy rope 18 runs from the winch 16 to a deflection roller 19 which is fastened to the head piece of the outermost telescopic section or to one of the collars of the upper telescopic sections.
  • the guy rope is guided from the deflection pulley to the tip of the guy block 14, where the fixed point of the guy winch 16 is opposite.
  • the resultant of the guy rope 18 meets the resultant of the fixed guy wire 17 at almost one point.
  • the outer telescopic section 9 additionally carries a folding tip 20 through which a longer boom length can be reached.
  • deflection rollers 21 are mounted, over which the hoisting rope runs in the usual way.
  • the hoisting rope reeving and the hoisting winch is of a common type and is therefore not described in detail.
  • the guy rope 18 is stretched over the winch 16 in accordance with the extension length or the seesaw angle.
  • the guy rope is anchored with a constant force that is so great that the guy rope 18 sags by a certain amount in the unloaded state of the boom. This slack is only lost when the boom is loaded by a load to be lifted.
  • the Measure the sag so that the boom cannot bend beyond an allowable dimension.
  • the winch 16 is arranged in the upper region of the guy bracket 14 so that no additional deflecting roller is required for the guy rope.
  • 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.
