Definitions

  • the invention relates to a crane, in particular a large mobile crane, with a lower crane frame, an upper crane frame rotatably arranged thereon, which has a lightweight construction and is provided with additional load-increasing devices.
  • Such a large crane with a crane subframe, a crane upper frame, a first main boom, a luffing jib, a lower luffing support and an upper luffing support as well as with a super lift device is known and is in principle successfully used in practice for lifting heavy loads (cf. DE -C2-31 08 454).
  • the invention specified in claim 1 is therefore based on the problem of creating a crane device which saves a second complete crane, in particular a large crane, and which increases its load-bearing capacity without the need for a second crane, i.e. without taking up a larger footprint and is therefore more economical.
  • the object is achieved according to the invention in that a second main boom, which is supported on a platform, is articulated on the first main boom via an essentially horizontally arranged supporting structure.
  • the advantage of this design not only includes an increase in load capacity of almost 100%, hardly any additional space or floor space is required, and not only very heavy transport objects but also very long objects can be lifted.
  • FIG. 2 An advantageous embodiment of the invention is specified in claim 2.
  • the development according to claim 2 is that the structure consists of an original luffing jib, which is used as a pressure support, and that the structure is held by means of guy rods or cables, to which a crossbar is attached.
  • the advantage of this solution is that an existing boom can be taken over and that the crossbar is clearly centered.
  • An improvement of the invention is that the crane-side pulley is connected to ropes from the hoisting winches of the crane upper frame. This results in an advantageous symmetrical arrangement of the assemblies on both sides.
  • At least two hydraulically operated cable lifting devices are arranged on the crossmember, to which load-carrying means are attached.
  • Such a design supports any height and therefore hardly takes up space below the cross member, which can thus be kept free for the load or the load stroke.
  • the supporting structure consists of a bending beam articulated on the first and on the second main boom and that the upper roller sets of the two pulley blocks are mounted directly on the bending beam.
  • a further embodiment of the invention consists in that the structure consists of a tie rod forming the base of a triangle and of supports forming the triangular legs. This saves a too heavy bending beam without having to accept a loss of overall height.
  • the task set out is further achieved according to a second alternative in that a first main boom and a second main boom are coupled by means of a relatively short pressure rod, that at least two guy rods or ropes are articulated on a stationary platform and that a crane-side pulley system with ropes the hoisting winches of the upper crane frame and a pulley facing away from the crane can be actuated with ropes from hoisting winches of the platform.
  • a correspondingly short pressure rod the roller sets for the pulley blocks are accordingly close together, so that the structure can shrink considerably, provided that an approximately trapezoidal space underneath is sufficient for the necessary lifting work.
  • a mobile platform is provided for mobile use instead of the stationary platform, which can be moved in parallel with the crane subframe in parallel trajectories.
  • the advantage of this is not only being able to lift long objects, but also to be able to raise.
  • the load can be connected to the platform at least temporarily by means of a coupling frame for the travel process.
  • the second main boom is arranged essentially upright. This solution is particularly suitable for heavy objects to be transported in a horizontal position, e.g. Refinery columns.
  • a further development of the invention is that the cable lifting devices can be moved horizontally on the supporting structure. Such a device enables the said columns to be erected, lifted and laterally lifted in refineries.
  • a hydraulic cylinder with its cylinder housing is rigidly arranged and another hydraulic cylinder is articulated with its cylinder housing, the piston rods being articulated on the second main boom and engaging in external support points.
  • Fig. 1 shows a mobile lattice boom crane, consisting of a crane subframe 1, a crane upper frame 2, a first main boom 3, a luffing jib 4, a lower luffing jib 5, an upper luffing jib 6 and a super lift device 7 to increase the load capacity.
  • Such an assembly is regarded as a basic device and serves as the basis for the present invention.
  • the upper crane frame 2 which is rotatably arranged on the crane subframe 1, has the first main boom 3, which is of lightweight construction, and in addition to the additional load-increasing devices, such as the super lift device 7 is now articulated on the first main boom 3 via a substantially horizontally arranged supporting structure 30, a second main boom 8, which is supported on a platform 10.
  • These two described sides of the large crane thus form a lifting frame which in the area of a load 41 has a considerable amount of free space, i.e. Has displacement (Fig. 1).
  • the structure 30 is formed from an original luffing jib 4, which is used as a pressure support 4a, and the structure 30 is held by means of guy rods or ropes 11, to which a cross member 12 is attached.
  • Two upper roller sets 12a and 12b for two pulley blocks 13 and 15 are mounted in the traverse 12.
  • the crane-side pulley 13 is connected to ropes 14a and 14b from the lifting winches 14 of the crane upper frame 2.
  • the pulley 15 facing away from the crane side is connected to ropes 16a and 16b from lifting winches 16 arranged on the stationary platform 10.
  • the first main boom 3 and the second main boom 8 can be designed in exactly the same way for economical production to guarantee.
  • At least two hydraulically operated cable lifting devices 17 are arranged on the cross member 12, to which load-carrying means 40 for the load 41, which may consist of cables, are fastened.
  • These rope lifting devices 17 can be used, for example, if the rope capacity of the lifting winches 14 and 16 should not be sufficient for a special lift.
  • the supporting structure 30 consists of a bending beam 18 articulated on the first and on the second main boom 3 and 8, and the upper roller sets 12a and 12b of the two pulleys 13 and 15 are mounted directly on the bending beam 18.
  • the bending beam 18 is replaced 1, the two guy rods or ropes 11 and the traverse 12.
  • the upper roller sets 12a and 12b of the two pulley blocks 13 and 15 are mounted directly on the bending beam 18.
  • the hydraulically operated cable lifting devices 17 are arranged directly on the bending beam 18. This means that different lifting devices can be used variably.
  • the cable lifting devices 17 described in FIG. 2 are mounted directly on the bending beam 18, so that the space below the bending beam 15 is free for the load 41.
  • the supporting structure 30 consists of a tie rod 19 forming the base of a triangle and of supports 20 and 21 forming the triangle legs.
  • the pull rod 19, the two Supports 20 and 21 and guy ropes 22 replace the pressure support 4a shown in FIG. 1, the two guy rods or ropes 11 and the crossbar 12.
  • the rope lifting devices 17 shown in FIG. 2 are mounted directly on the pull rod 19. For the lifting height the same advantages result as in the solutions according to FIGS. 3 and 4.
  • FIG. 6 An alternative solution is shown in FIG. 6.
  • the crane in particular a large crane, is also provided with a crane subframe 1, a (rotatable) crane upper frame 2 arranged thereon, which has a lightweight main boom 3 and with additional load-increasing devices, such as e.g. the super lift device 7 is provided.
  • additional load-increasing devices such as e.g. the super lift device 7 is provided.
  • first main boom 3 and the second main boom 8 are coupled by means of a relatively short pressure rod 23, furthermore at least two guy rods or ropes 9 are articulated on the stationary platform 10, and a pulley 13 on the crane side with ropes 14a and 14b is out of the lifting winches 14 of the crane upper frame 2 and a pulley 15 facing away from the crane can be actuated with ropes 16a and 16b from lifting winches 16 of the platform 10.
  • the short pressure rod 23 couples the first main boom 3 to the second main boom 8.
  • a base 24 and a plurality of support beams 25 are provided for stationary use instead of the crane subframe 1.
  • the load 41 can be connected at least temporarily to the platform 26 by a coupling frame 28 for the travel process.
  • the one shown in FIG to 6 shown stationary platform 10 replaced by the mobile platform 26, which can be moved, for example, on two slideways (movement paths 27) in parallel with the crawler track.
  • the load After the load has been raised, it is connected to the platform 26 by at least one coupling frame 28, but only for the movement process.
  • the second main boom 8 is arranged substantially upright. This creates an even higher space for the load 41 which, as drawn, consists of a column for a refinery.
  • the cable lifting devices 17 can be seen to be horizontally displaceable on the supporting structure 30, a trolley 29 being used.
  • FIG. 11 shows a view A according to FIG. 9, so that the vertical second main boom 8 can also be seen from the side, as well as guy rods or cables 9 and ballast 34 on a platform 32.
  • the essentially upright second main boom 8 is supported on vertically actuatable hydraulic cylinders 35 and 36.
  • the hydraulic cylinder 35 is rigidly arranged with its cylinder housing as shown, and another hydraulic cylinder 36 is articulated with its cylinder housing, the piston rods each being articulated on the second main boom 8 and resting on the platform 32 spaced apart in external supports.
  • the hydraulic cylinders 35 and 36 serve essentially as an assembly aid to compensate for inaccuracies in the articulation points in the area of the supporting structure 30.
  • the second main boom 8 is here via four hydraulic cylinders 35, 36 mounted on the platform 32 and two guy rods or ropes 9 provide lateral stability for the second main boom 8, and in addition the ballast 34 increases the stability of the entire system.
  • the four hydraulic cylinders 35 and 36 which are rigidly and articulated in pairs on the platform 32, not only enable a height correction, but also an angle correction of the second main boom 8.
