Definitions

  • the invention relates to a crane with a telescopic tower attached to an uppercarriage or the rotating platform of a portal, the inner telescoping section of which is hingedly connected to a boom, with a three-part boom consisting of the inner boom articulation part, the boom center piece and the outer boom extension by means of guy ropes that run over guy supports, anchored to a fixed point on the superstructure or the rotating platform.
  • the object of the invention is to provide a crane of the type mentioned, in which the three-part boom can be folded like an accordion into its transport position, without having to re-bolt the boom parts from the transport position to re-erect, and in which have the two outer boom parts pivot regardless of the specified rope geometry of the guy ropes when erecting or lowering in the direction of the inner boom part in order to be able to avoid obstacles, for example.
  • this object is achieved in a crane of the generic type in that the boom link piece is articulated to the boom center piece around a top axis located in the area of the top chords and the boom center piece is articulated to the boom extension around a cross axis located in the area of the bottom chords and that an auxiliary winch is provided , with which a central guy support articulated in the outer area of the jib articulation piece, from which the guy rope of the jib extension runs to a fixed point on the jib extension, is pivotable in the direction of the boom linkage.
  • the cantilever parts Due to the articulated connection of the cantilever parts to one another, one in the area of the upper chord and the other in the area of the lower chord, these can be concertina-like folded into their transport position, in which they lie parallel to each other.
  • the jib parts do not need to be turned over relative to their transport position, because the arrangement of the joints allows the jib parts to be pivoted into their extended position.
  • the cantilever parts are also stabilized against one another, because the cantilever parts are supported on one another at their abutment surfaces by abutments which run at right angles to the central plane of the cantilever parts.
  • the boom center piece and the boom extension can be pivoted in the direction of the boom articulation piece when the tower has not yet been fully telescoped, so that obstacles can be avoided during air assembly.
  • the jib center piece and the jib extension can be pivoted upwards with respect to the jib link so that only the jib link on which the trolley can be moved can be used for crane operation.
  • the assembly and disassembly work can be considerably shortened and simplified after changing the place of use, with additional air assembly being possible by avoiding obstacles. Elaborate bolting and bolting work are avoided in order to bring the crane into its transport position or to erect it again from the transport position.
  • the rope of the auxiliary winch is expediently reeved between the upper end of the central guy support and the point of application on the jib linkage.
  • the fixed point of the auxiliary winch rope is expediently on the middle part of the boom, and preferably approximately in the central area thereof. This type of attachment of the auxiliary winch rope introduces an additional torque into the middle of the boom when it is pivoted.
  • the boom link piece in the extended state of the boom, is centered in relation to the boom center piece in the region of the lower flange by a nose engaging in a fork.
  • the fork can be V-shaped to facilitate the retraction and centering of the complementary nose.
  • the auxiliary winch is expediently arranged on the inner end region of the boom articulation piece.
  • the boom link piece and the boom center piece consist of lattice girders with a triangular cross section and that the joint connecting them in the region of the upper chords is a swivel-fold joint.
  • This configuration makes it possible to rotate the boom parts folded against one another for the purpose of transport around the swivel joint in such a way that they lie next to one another in a space-saving manner in the transport position.
  • the boom center piece in the region of the outer end of its upper flange is connected to an angled pivotable about a transverse axis and connected to the guy rope of the boom extension
  • Auxiliary support is provided, the angled part of which extends over the boom extension when the boom center piece and the boom extension are folded together.
  • This auxiliary support improves the lever arm when the boom center piece and the boom extension are pivoted in the direction of the boom linkage.
  • the auxiliary support can be provided with these centering brackets in the folded state. Expediently spring clips are provided on the auxiliary support for catching and fixing the rope.
  • the boom center piece or the boom extension is provided with a catching device for the lifting rope.
  • This catching device can consist of a pivotable hook which is pivoted out by the rope of the auxiliary winch.
  • the fastening of the rope of the auxiliary winch of the catching device expediently forms the outer fixed point of the rope.
  • the hook forming the catching device can be pivoted out against the force of a spring.
  • the hoist rope is kept constantly tensioned by a slip clutch.
  • the trolley travel drum is located on the side outside the jib link. It is also necessary to keep the trolley rope under tension even during assembly and disassembly.
  • one end of the trolley rope is fastened to the trolley by wrapping a deflecting roller which is displaceable against spring force on the trolley.
  • the other end of the trolley rope is expediently on attached to a roller that can be tensioned by a ratchet.
  • the trolley rope expediently runs at the jib tip via a deflecting roller which can be moved against spring force and can be moved on a block. In this way, changes in length of the trolley rope can be compensated.
  • a catching device for the trolley rope is arranged in the area of the articulated connection of the middle section of the boom and the extension of the boom.
