Definitions

  • the present invention relates to a crane with an about an upright axis rotatable superstructure, one on the superstructure about a horizontal axis tiltable articulated boom, a luffing device for rocking up and down the boom, and a counteracting the moment of the boom operating ballast.
  • the present invention is therefore based on the object, an improved Crane of the type mentioned, the disadvantages of the prior art Avoiding technology and the latter develops in an advantageous manner.
  • the erection of very long boom combinations be achieved without to provide redundant ballast for the operation.
  • the crane is thus characterized in that a erecting auxiliary frame is provided, according to the superstructure and / or the operating ballast cantilevered at the rear and with a righting ballast for erecting the boom is connectable.
  • the Aufrichteangesrahmen can thereby on the Rear of the superstructure or the attached operating ballast attached be that from the opposite side of the boom from the boom protrudes to the rear and has an extended lever arm, where the Rearing auxiliary ballast can be attached.
  • the righting help ballast becomes special attached for erecting the boom on the erecting auxiliary frame and for the Crane operation removed. Due to the Aufrichteosrahmen he has a very large Lever arm, the Nachvornekippen the crane when erecting even long boom prevented.
  • a preferably mobile auxiliary crane to be attached which is used to assemble the crane place.
  • the erecting auxiliary frame has for this purpose suitable attachment means to which the auxiliary crane can be attached as Aufrichteangesballast.
  • the usage the mobile auxiliary crane, which actually serves to build the crane, as additional ballast has the advantage that additional low loaders can be saved with which otherwise additional revolving ballast transported to the site would have to be.
  • the erecting auxiliary frame for crane operation is off its rearwardly projecting position in another crane operating position Can be brought in the Aufrichteangesrahmen substantially within that of the superstructure or the operating ballast fixed thereto pivoting range lies.
  • the rear-projecting erection frame would be disturbing, so that it advantageously from its rearwardly projecting upright position can be removed.
  • the erection frame can be pivoted on the uppercarriage and / or the Operating ballast articulated and by a pivoting device between the post swung rear projecting upright position and a crane operating position become.
  • the pivot axis about which the erection frame can be pivoted advantageously extends substantially horizontally in the region of Upper carriage, so that the erection frame by the pivoting device after can be swung up in the said crane operating position.
  • the Pivoting device can basically be designed differently.
  • a preferred embodiment of the invention is at least one hydraulic power lift provided for upward pivoting of Aufrichteevers.
  • the erection frame can be detached with releasable attachment means be attached and dismounted. This allows the erection frame after the Erecting the boom are completely disassembled, so that in crane operation no disturbing effect of Aufrichterahmens is given.
  • the previously described embodiment after which the erection frame in an upward tilted crane operating position can be brought, the advantage that the Aufrichtahmen can be used as additional ballast use.
  • the trailing means of the erecting auxiliary frame to which the erecting auxiliary ballast can be hung in the invention two in the longitudinal direction the Aufrichteanges spaced apart fasteners have, whose distance is adjustable from each other.
  • the adjustable distance of the Suspension points allow various sized mobile auxiliary cranes as Aufrichteangesballast to use.
  • the auxiliary cranes at their Bodenabstützungen be hung up. In so far as their distance vary depending on the mobile crane can, it allows the variable-spacing formation of the fasteners on the erecting auxiliary frame, differently shaped auxiliary cranes on the erecting auxiliary frame attach.
  • the fasteners even at a fixed, unchanged distance to the erecting auxiliary frame be arranged, if it is sufficient, with only a certain additional ballast or mobile crane.
  • the fasteners of cross members be formed, of which at least one in the longitudinal direction of the erecting auxiliary frame changeable, preferably arranged displaceably on the erecting auxiliary frame is.
  • the cross beams cantilever transversely to the longitudinal direction of Aufrichteangesrahmens beyond this. They can hook at their ends or other suitable fasteners have, where support cables or the like for attaching the Rearing aid ballasts can be attached.
  • the height adjustment device can be designed differently.
  • the height adjustment device is designed such that each breakpoint the towing means is separately height adjustable.
  • the invention associated with each fastener each have a threaded spindle be, with the help of which the attachment point is height adjustable.
  • the erection frame may vary in length.
  • the over the operating ballast Rearwardly projecting cantilever of the erection frame is preferably adapted to the length of the erectile boom that a suitable Aufrichteangesballast sufficient.
  • the Rigid auxiliary frame a projecting beyond the operating ballast to the rear Have Kragander, at least the distance of the operating ballast center of gravity from the superstructure axis of rotation corresponds.
  • the crane shown in the figures has an undercarriage 1 with a chassis 2, which is designed in the illustrated embodiment as a crawler chassis and comprises two right and left arranged caterpillar tracks.
  • a chassis 2 which is designed in the illustrated embodiment as a crawler chassis and comprises two right and left arranged caterpillar tracks.
  • On the undercarriage 1 is about an upright axis of rotation 3, a revolving stage or a superstructure 4 rotatable stored.
  • the upper carriage 4 carries a boom 5, which is about a horizontal rocking axis 6 is articulated to the superstructure 4 and in a conventional manner a hoist rope drain over its top.
  • the boom 5 can be about a guy 8 to the rocker axis 6 up and tipped off and erected from the position shown in the drawings.
  • the bracing 8 is guided over a support arm 9 to the bracing. 8 to give a cheaper lever arm.
  • the support arm 9 is one to the rocking axis 6 parallel axis swiveling.
  • the bracing is known per se Way over multiple reeving adjustment cables 10 in the area of the operating ballast 7 led to the superstructure.
  • the erecting auxiliary frame 11 preferably consists of two parallel longitudinal members, which several transverse profiles are welded together. It is understood that the erecting auxiliary frame 11 but also be designed as truss or otherwise could.
  • the erecting auxiliary frame 11 extends in a flat uprising of the crane essentially horizontally to the rear, substantially at the level of the upper side
  • the erecting auxiliary frame 11 is arranged so high, that a mobile auxiliary crane, which is used for the construction of the crane, under he is mobile.
  • the cross member 12 are advantageously so from each other spaced, that their distance from the distance of ground supports of the auxiliary crane equivalent.
  • the side out of the auxiliary crane extended floor supports attached by means of steel ropes 15 to the cross members 12, so that the auxiliary crane forms a rearing aid ballast 16.
  • the erecting auxiliary frame 11 can in principle be rigidly bolted to the uppercarriage 4 so that he takes the drawing position drawn in the figures.
  • the erecting auxiliary frame is then aborted and removed.
  • the operating ballast 7 alone is sufficient for the operation of the crane in particular then, if this is operated only with a steeply erected boom.
  • the erecting auxiliary frame 11 on the Upper carriage 4 also be pivotally mounted, and advantageously by one to Wippachse 6 parallel axis.
  • the erecting auxiliary frame 11 can be a Swivel drive 17 assigned for example in the form of a hydraulic power lift be, with the help of which the erecting auxiliary frame 11 from the substantially horizontally rearwardly projecting upright position into an operating position can be pivoted upward, which is indicated by dashed lines in Figure 2.
  • the upwardly pivoted operating position of Aufrichteangesrahmen 11 is at least so far pivoted that he over obstacles standing on the ground away swings.
  • the erecting auxiliary frame 11 can be as far behind be pivoted above, that he is within the from the trailing edge of the superstructure 4 defined pivoting circle comes to rest. Compared to Figure 2 would be to swing the erecting auxiliary frame a little further upwards. Not to collide with the Verstellverseilung 10, the Aufrichteangesrahmen in the area its articulation possess a U-shaped profile, so that the stranding between can pass through the two thighs.
