Definitions

  • the invention relates to a ring lift crane according to the preamble of Claim 1.
  • a genre-trained ring lift crane is known from the company brochure Mannesmann Demag special machinery "Ringlift Cranes" CC 2000 RL; CC 4000 RL, Issue 11/82.
  • This known ring lift crane has one that can be raised and one a circular lane forming ring, which consists of several interconnectable Segments.
  • An undercarriage is rotatable within the ring connected superstructure and having multiple winches.
  • the uppercarriage is connected to both ends with an adapter, which is by means of rockers connected to one another on the adapters Support roller sets on the circular track of the ring.
  • One is an adapter to accommodate a counterweight and the other adapter as a supporting element for a boom which can be arranged articulated at the free end of the adapter (Main boom + mast) trained.
  • the rotary movement of the ring lift crane is by means of a toothed ring arranged on the inside of the ring and in it engaging pinion mounted on rockers.
  • To stabilize the Overall construction is the undercarriage with different reinforcement struts Sections of the ring connected.
  • the tip of the mast is on the one hand Bracing with the counterweight and on the other hand via a length-adjustable Rope guying connected to the head of the main boom.
  • This Ringlift crane consists of a stand-up ring that forms a circular track and a construction inside the ring with a kingpin and one Platform which is provided with a sleeve for receiving the kingpin.
  • the platform is connected to an adapter in each of the two end areas Support roller sets on the ring by rolling on the adapters, whereby the center of the ring forms the axis of rotation for the platform.
  • On the platform there are several winches and a counterweight on the rear adapter.
  • On the front adapter there is a main boom and a mast (counter jib) hinged attached.
  • the one-piece ring is secant and within the Stiffened ring struts.
  • Ring lift cranes of the type described above can only be used in the prior art an elaborate assembly or disassembly procedure erected or filed become.
  • the object of the invention is to provide a ring lift crane of the generic type, which can be easily erected and stored.
  • the mast and the main boom are erected in a simple manner or store.
  • the guy support and the auxiliary winch are preferably both the guy support and the auxiliary winch arranged on one side outside the working area of the main winches.
  • the guy support and auxiliary winch are connected by a cable drive with correspondingly on the free end of the guy support as well as on the support rods arranged roller sets.
  • the length and the linkage on the mast of the Guy supports are chosen so that after erecting the mast Head area of the guy support can be placed on the counterweight. This has the Advantage that the winch operation is also free from the side of the guy support remains accessible.
  • FIG. 1 shows a schematic diagram of the arrangement of a mast 1 in a first position before its erection.
  • the movable ring lift crane shown here consists of an undercarriage, here a crawler track 2 and one arranged above it, cantilevered support element designed on both sides 3.
  • the support element 3 is rolling in both end areas on the one Crawler chassis 2 ring from.
  • the ring is designed as a double ring 4.
  • the double ring 4 is by means of several supports 5 on the Floor 6 elevated.
  • To the erected ring lift crane as a whole using the To be able to move crawler tracks 2 are at the ends of the support element 3 one piston-cylinder unit 7,7 'each.
  • the piston-cylinder units 7,7 ' are designed so that they can lift the ring lift crane as a whole to to lock the support element 3 with the crawler track 2.
  • the main winches 8-11 are arranged in the middle of the Main element 3.
  • a counterweight 12 is arranged on the support element 3, which by Support rods 13, 14 is supported laterally.
  • the mast 1 is arranged articulated.
  • Erecting and placing the mast 1 on the counterweight 12 facing Side a guy support 15 arranged articulated.
  • the free end of the Guy support is on the one hand with a guy 16 and on the other hand with a length-adjustable rope guying 17 connected.
  • the other end of the rope guy 17 is with the head region of the support rods 13, 14 of the counterweight 12 connected. From there, the free end of the rope 32 runs to one on the Support element arranged auxiliary winch 20.
  • the direction of installation for the guy support 15 is marked with an arrow 18.
  • To the mast 1 level with the To be able to arrange the support element is, in the alternative, a platform 19 on the head region underpinned.
  • FIG. 2 shows a further position in which, after the guy support 15 has been set up and the tension 16 under tension is the mast 1 shortly before erection.
  • the installation direction for the mast 1 is marked with an arrow 21.
  • Figure 4 shows in a last position the end position of the mast 1 just before Raising the main boom 22.
  • the details of this final phase are as Detail A shown in Figures 5 and 6.
  • the end region of the guy support 15 has a 16 for fastening the guy web plate 25 provided with a connecting eye 24.
  • a roller set 30 is arranged, which with a a tab 33 swinging on the guy support 15 arranged roller set 31st interacts.
  • the two roller sets 30.31 is the one already mentioned Rope guying 17 arranged, the free rope end 32 led to the auxiliary winch 20 is.
  • the end of the guy support 15 is below the roller set 31 Support plate 35 arranged.
  • FIG. 5 now shows a position in which, by tightening the cable guying 17 the guying 16 is relieved to the shortest distance, so that it according to the arrow 34 from the end of the guy support 15 to the support rods 13,14 can be reassigned.
  • the rope guying 17 can be carried out according to FIG of the support plate 35 are placed on the upper edge of the counterweight 12. The guy support 15 is thus relieved and the mast 1 is fixed via the guy 16, which is now fixed to the support rods 13,14 Counterweight 12 is connected.
  • Figure 7 shows a view in the direction X in Figure 2. In this view is the one-sided Arrangement of the auxiliary winch 20 and the roller set 30 outside the area of Main winches 8-11 recognizable.
