Definitions

  • the invention relates to a mobile crane with a long main boom.
  • the object of the present invention is now main boom with long boom lengths without being able to erect a derrick boom, which means the entire erection process is facilitated and in particular long main boom can be erected are.
  • the main boom is divided into two and in such a way at a pivot point connected that it is kinkable when straightening up in order to stretch it or almost stretched final assembly position. This erect one The main boom does not require any restraint.
  • a special intermediate piece with at least one is preferably on the main boom a pressure link, which is arranged pivotable about a pivot point, available. This intermediate piece can be placed anywhere on the boom be arranged.
  • a fold-out support can be articulated on the pressure link.
  • the mobile crane can have an auxiliary winch that can be used to pull an auxiliary rope down or can be wound up.
  • an adjustment winch can be provided, via which an adjustment tab is pullable to the top of the pressure link, where it can be fixed with a hook.
  • the adjustment wrist can be used to straighten the kinked front main boom part retractable.
  • Two pressure links can preferably be arranged parallel to one another.
  • the swivel axes of the two pressure links can be inclined to the main boom be arranged, with the inclined arrangement of the pivot axes of the two Push rod a lateral bracing can be achieved, which the Lateral stability of the boom is further increased.
  • a mobile crane 10 is shown with a main boom 12, the Main boom 12 from a lower boom part 14 and an upper boom part 16, which is pivotally connected to one another about a pivot point 18 are.
  • the entire boom length of the main boom 12 is on the Floor built up.
  • This main boom has a special intermediate piece, which is provided with a knee joint and a pressure link and instead of one Standard intermediate piece is installed. The installation of this intermediate piece can anywhere on the boom.
  • FIGS of the mobile crane 10 The structure of the boom and the components is shown in FIGS of the mobile crane 10, which are necessary for erecting the main boom 12, in described in more detail.
  • FIG. 5 shows that a pressure link 20 is located on the upper part of the main boom 16 is provided, which is about an articulation point 22 with respect to the upper boom 16 is pivotable.
  • the pressure link 20 is when the main boom is erected lifted a little from the transport position with an auxiliary crane 24 until it reaches itself with respect to the articulation point 22 results in a lever arm. With a fold-out Support 26, the pressure link 20 is held in this position.
  • two rollers 28 and 30 are arranged at the top of the Pressure control arm 20, two rollers 28 and 30 are arranged.
  • An auxiliary winch 32 is provided on the mobile crane 10, via which an auxiliary rope 34 is pulled off is and in the rearward sequence, as shown partially in dashed lines in Figure 5 is guided up to a hoist winch 36. There the auxiliary rope 34 with the the hoisting winch is coupled to the hoisting rope. With the auxiliary winch 32 is then by means of the auxiliary rope 34 the hoist rope pulled forward to one Fixed point 38 near the top of the upper part 16 of the main boom 12. There the hoist rope is bolted to the fixed point 38.
  • FIG. 7 The erection process of the pressure link 20 is shown in FIG.
  • the pressure link 20 By winding of the hoist rope on the hoist winch 36, the pressure link 20 automatically stands up and tensions front guy rods 40.
  • On the main boom 12 is an adjusting winch 42 is arranged, with which an adjustment tab 44 is connected.
  • the upper adjustment tab 48 By unwinding an adjustment rope 46 from the adjustment winch 42 and simultaneous winding of the Hoist winch 36, the upper adjustment tab 48 is pulled to the tip of the pressure link, until a bolt 50 provided on the upper adjustment lug 48 in a hook 52 engages (compare FIG. 7 and in particular detail A to FIG. 7).
  • the hook 52 can be used with a short auxiliary rope 54 (see detail A to figure 7) are raised.
  • the short auxiliary rope 54 with the long one Auxiliary rope 34 connected so that the necessary force on the auxiliary winch 32nd is applicable.
  • the lower part 14 of the main boom When raising the main boom, as shown in Figures 2 to 4, the lower part 14 of the main boom is first raised (compare Figure 2). Here, the tip of the upper part of the boom 16 rolls onto the floor or is suspended using an auxiliary crane. While standing up of the lower part 14 of the main boom 12, the adjustment tab 44 is ongoing decreased so that the boom head weight lies on the ground and therefore does not have to be erected. After the lower part of the main boom has reached a corresponding angle to the ground and consequently the Masses were moved closer to the crane by pulling in the adjustment tab 44 the upper part 16 of the main boom is raised by means of the adjusting winch 42. The main boom is still at an incline front so that the boom can be brought into a stretched position without the A restraint device is required. The boom is up to a stop pulled and the adjustment tab 44 is fixed. Through this additional back tension the stability of the boom 10 is increased.
