Definitions

  • the invention relates to a lattice piece for a mobile large crane and a method for erecting such a lattice piece.
  • lateral stiffeners were attached to both arms on both sides and adjusted with a double derrick (as proposed in the DE 100 02 917 A1 ).
  • the cantilevered outriggers are to be pivotable on a common axis, all solutions have in common that the width of the assembled cantilever was always greater than the height.
  • the known boom in the rocker plane less resilient than perpendicular to the rocker plane.
  • the maximum length to be erected is also limited by the cross-sectional values of the jib in the teetering plane.
  • Object of the present invention is to provide lattice pieces that can be used in a mobile crane, with extremely high loads can be lifted to great heights, the individual lattice pieces still remain road transportable.
  • a lattice piece for a mobile large crane which consists of four corner posts and diagonal bars connecting them, so divided into two parts that two interconnected corner stems each part of the diagonal bars is articulated hinged.
  • the lattice pieces according to the invention can be transported in this disassembled form.
  • large lattice pieces can be created with a profile which has a cross section of, for example, 8 x 6 m and a length of 11 m.
  • the mesh pieces of the present invention can be assembled into a correspondingly powerful boom.
  • the lattice pieces according to the invention can be transported with so-called flat containers. These have dimensions that are uniform worldwide.
  • the disassembly of the lattice pieces into two parts is preferably chosen such that a separation takes place in the width as well as in the height of the lattice pieces.
  • the lattice pieces are to be designed so that the assembly and disassembly of the respective lattice piece can be carried out economically. This means that the construction and dismantling of the lattice piece must be done in a reasonable amount of time, with the least possible aids and taking into account the safety during assembly and disassembly.
  • additional zero rods can be hinged hinged to two interconnected corner stems. These zero bars serve to increase the stability. But they are not fundamentally necessary. In their place, according to another preferred embodiment of the invention, a rigid connection between the individual lattice pieces occur.
  • the lattice pieces can advantageously have corner stems, which consist of profiles which have fork-finger connections at their ends. At each corner post four zero bars and four diagonal bars can be articulated.
  • At least a portion of the zero bars and / or the diagonal bars may be telescopic.
  • Both the zero bars and the diagonal bars can be fixed in the construction in each case by means of bolted connections to the corner posts or with one another.
  • the profile of the corner handles made of two angled box-shaped miteinender welded sheets, to which each of the fork-finger connections are welded.
  • the connection between the corner stems and the diagonal and zero bars is rigid.
  • positioning devices can be provided for positioning the diagonal bars and / or zero bars in the disassembled state. So the transport units are securely kept in touch.
  • the positioning devices can also remain in the constructed lattice piece and in the crane use on or in the lattice piece.
  • a further advantageous embodiment of the invention is that an additional spatial diagonal is provided in each grid element.
  • the zero rods can roll during erection over arranged at their free ends rollers along the corner stems.
  • FIG. 1 an inventive lattice piece 10 is shown in perspective.
  • This lattice piece consists of four corner stems 12, which are connected to each other via diagonal bars 14 and 16 and zero bars 18 and 20, respectively.
  • a lattice piece 10, as in the FIGS. 1 to 5 is shown, for example, has a length L of 11 m, a width B of 8 m and a height H of 6 m.
  • this lattice piece In order to transport this lattice piece on the street, it is divided into two parts. In this case, two lattice piece halves, each comprising two corner handles 12, formed. These lattice piece parts are starting from the constructed lattice piece according to FIG. 1 formed by that corresponding bolt connections to the diagonal bars 16 and the zero bars 18 are solved at least on one side. The respective divided lattice pieces 10 are then in a folded position, as in FIG. 2 is shown transferred. For this purpose, the zero rods 20 are folded and the diagonal bars 14, which are telescopic, ateleskopiert. The corresponding folded or extended state is in FIG. 3 represented by the distinction of solid to dash-dotted lines. As in FIG.
  • the diagonal bars 14 are each struck at pivot points 22 and 24 of the corner stems 12. In extended position, as in solid line in FIG. 3 is shown, the diagonal bars 14 are bolted via bolts 26 in its extended position. The zero bars 20 are struck in each case via pivot points 28 on a corner post 12. The opposite free end can be bolted to the opposite corner post 12.
  • FIG. 4 is a view from above shown.
  • the corner handles 12 are connected to each other via the diagonal bars 16 and the zero bars 18.
  • the diagonal bars 16 are pivotable about pivot points 28, while the zero bars 18 are pivotable about pivot points 30 and 32, respectively.
  • the pivoted position is in the FIG. 4 represented by dash-dotted lines.
  • the respective free ends of the diagonal bars 16 and the zero bars 18 are bolted to the opposite Anbolz Vietnameseen the corner post 12.
  • FIG. 5 there are no spatial diagonal bars.
  • the corner handles 12 may be made of any profile.
  • the profile according to the embodiments according to FIG. 6 made of two angled and welded sheets 36, 38.
  • the cross-sectionally square profile has a side length of about 800 x 800 mm.
  • At the corner piece guide plates 40 may be welded to corresponding stiffeners 42 for receiving the zero bars or diagonal bars. With 44 bolt connections are indicated here.
  • the profiles of the diagonal bars 14, 16 and zero bars 18, 20 is arbitrary. They consist for example of a welded pipe construction or a welded construction of straight or bent sheets. In any case, the profiles are formed but kink-proof.
  • FIG. 7 is purely schematic and exemplified the process sequence for the construction of the lattice piece according to the invention.
  • Figure 7a is shown as a first transport unit 46 is removed by means of an auxiliary crane not shown here from a flat container, also not shown, on which the first transport unit has been transported and is stored at a distance B from a second transport unit 48.
  • This second transport unit 48 was previously also taken up by a flat container with the auxiliary crane and to the in Figure 7a shown position.
  • the lower diagonal bars 16 are swung out and bolted, resulting in the distance B of 8 m.
  • the diagonal bars 16 and the zero bars 18 are attached to an auxiliary crane.
  • the upper diagonal 16 and the upper zero bars 18, that is, the diagonal 16 and the zero bars 18 of the upper disc swung out and bolted by means of bolts 50 with the corner stems 12 ,
  • the zero rods 20 can embrace the corner stems 12 fork-shaped. In this position, the zero rods 20 can be bolted to the corner stems 12. According to the embodiment in the Fig. 1 and Fig. 5 the zero rods 20 are bolted to corresponding tabs welded to the corner posts. Not shown here are roles similar to those in the FIG. 3 act described manner.
  • the pivot piece or the head piece (not shown here) can be made collapsible.
