Definitions

  • the invention relates to a chassis, preferably for a crawler crane, with a on a crawler carrier running crawler, which is articulated from each other Bottom plates consists, wherein formed on the bottom plates cams are, which engage in grooves of rollers arranged in the crawler, wherein Center the caterpillar track under the rollers.
  • FIG. 1 A caterpillar track according to the prior art is shown for example in FIG.
  • the crawler 12th comprises, on which a crawler 14 runs, which are articulated from each other Floor panels 16 is.
  • the bottom plates 16 approximately centrally cams 18th exhibit.
  • the cams engage in grooves 20, the all-round in rollers 22nd are provided (see Fig. 1a).
  • the rollers are arranged in the crawler support 12.
  • the crawler 14 is driven by a drive wheel 24.
  • Object of the present invention is to provide a generic suspension such educate that a jumping off the crawler also when driving over of bumps can be effectively prevented.
  • cranked Screws are inserted and held, holding the retaining plate to the bottom plate establish.
  • those at the top of the Base plates cast holes, which are used for holding the cores during the Casting process are required to be used for mounting of retaining plates.
  • two cranked screws are connected to one another via a transverse web connected over which the screws inserted in the bottom plates on this support.
  • the attachable to these screws holding plates can, for example be firmly connected to the bottom plate via two nuts.
  • the holding plates can, for example be made as a casting.
  • the holding plates can advantageously be trapezoidal and because of this design they can be soiled derive to the outside.
  • the invention also relates to a crawler for a chassis and a crawler crane with a chassis according to the invention.
  • Another advantage of the invention is that the chain is not in transit more sags. Thus, the middle piece in his Verbolzung essential lower jacked.
  • Fig. 2 is a chassis 10 of a crawler crane not shown in detail represented according to the present invention.
  • Fig. 2a shows a corresponding Section, wherein the features essential to the invention in an enlarged Representation of a detail of Fig. 2a in Fig. 6 are shown in more detail.
  • the chassis 10 has a crawler support 12 with a caterpillar track 14 running on it on.
  • the caterpillar track consists of articulated floor plates 16.
  • cams 18 are formed, which in circumferential grooves 20 are provided by arranged in the crawler support 12 rollers.
  • the caterpillar For example, by a drive wheel 24 in a conventional manner and Way powered.
  • Fig. 6 shows now in detail that laterally on the bottom plate 16 holding plates 26 are provided, the carrier-resistant baffles 28 behind or overlap.
  • a gap 30 In the conventional method of the chassis results between the holding plates 26th and the baffles 28, a gap 30.
  • the gap 30 is chosen so small that it is smaller is as the height of the cam 18. This is reliably prevents the cam 18th no longer lie in the groove 20.
  • the shape of the retaining plate results in particular from the sectional view according to 5 and from the top view of FIG. 7.
  • the holding plate is after appropriate plugging on the screws 36 by screwed onto the thread 40 of the screw 36 nuts 42 secured.
  • the holding plates 26, as shown in Fig. 7, preferably a trapezoidal shape, so that occurring in this area soiling be derived to the outside.
