Definitions

  • the invention relates to a chassis, preferably for a crawler crane, running on a caterpillar track crawler consisting of articulated floor plates, which are formed on the bottom plates cams, which engage in grooves arranged in the crawler track rollers, taking the crawler under Center the rollers on the side.
  • a chassis according to the preamble of claim 1 is made EP 0 533 502 A1 known.
  • FIG. 1 A caterpillar track according to the prior art is, for example, in FIG. 1 shown.
  • a chassis 10 which includes a crawler support 12, on which a track 14 runs, which consists of hingedly interconnected floor panels 16.
  • a crawler support 12 on which a track 14 runs, which consists of hingedly interconnected floor panels 16.
  • the bottom plates 16 approximately centrally cams 18 have.
  • the cams engage in grooves 20 which are provided circumferentially in rollers 22 (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 develop a generic suspension such that a dropping down of the crawler can be effectively prevented even when driving over bumps.
  • the object is achieved on the basis of a chassis according to the preamble of claim 1 by the combination with the features of the characterizing part of claim 1.
  • the holes bent screws can be used and held, which define the retaining plate on the bottom plate.
  • the holes cast in the top of the bottom plates which are required for holding the cores during the casting process, can be used to mount retaining plates.
  • two cranked screws are connected to one another via a transverse web, over which the screws introduced into the base plates are supported on this.
  • the attachable to these screws holding plates can be firmly connected, for example, two nuts with the bottom plate.
  • the holding plates can be made for example as a casting.
  • the retaining plates may advantageously be trapezoidal and due to this design, they can derive dirt 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 no longer sags during transport. Thus, the middle piece can be jacked much lower in his Verbolzung.
  • the loading of a crawler crane equipped with the landing gear according to the invention can be substantially improved on a low loader. So far, it was necessary that the lower chain of the track chain is fixed with specially designated chains. This additional laying around of chains around the lower chain center can be dispensed with during loading in the future.
  • Fig. 2 is a chassis 10 of a crawler crane not shown in detail according to the present invention shown.
  • Fig. 2a shows a corresponding section, wherein the features essential to the invention in an enlarged view of a detail of Fig. 2a in Fig. 6 are shown in more detail.
  • the chassis 10 has a crawler support 12 with a crawler 14 running on it.
  • the crawler consists of articulated floor plates 16.
  • cams 18 are formed, which are provided in circumferential grooves 20 arranged in the crawler 12 rollers.
  • the crawler is driven, for example, by a drive wheel 24 in a conventional manner.
  • Fig. 6 now shows in detail that 16 holding plates 26 are provided laterally on the bottom plate, the carrier-resistant baffles 28 behind or overlap.
  • a gap 30 In the conventional method of the chassis results in between the holding plates 26 and the baffles 28, a gap 30.
  • the gap 30 is chosen so small that it is less than the height of the cam 18. This is reliably prevents the cams 18 are no longer in the groove 20.
  • FIGS. 3, 4 and 5 The manner in which the holding plates 26 are connected to the bottom plates 16 results in detail from the FIGS. 3, 4 and 5 , In particular the Figures 3 and 5 , In particular the Figures 3 and 5 It can be seen that the bottom plates 16 have cast holes 32. In the cast holes access via openings 34 two mutually parallel cranked screws 36, wherein the screws 36 are connected to each other via a holding web 38. As is clear from the Figures 3 and 5 yields, on the one hand support the bent ends of the screws 36 and on the other hand, the support plate 38 on the corresponding wall of the bottom plate 16, so that here is given sufficient stability.
  • the cranked screws 36 have at their free end in each case a thread 40 (see. Fig. 4 ). On the corresponding screws 36 which consists of a casting holding plate 26 is attached.
  • the shape of the holding plate results in particular from the sectional view according to the Fig. 5 and from the top view according to Fig. 7 , As in Fig. 5 in detail shown, the retaining plate is secured by appropriate attachment to the screws 36 by screwed onto the thread 40 of the screw 36 nuts 42.
  • the holding plates 26 have, as in Fig. 7 represented, preferably a trapezoidal shape, so that occurring in this area contaminants are discharged to the outside.
