Definitions

  • the rear pivoting leg is articulated on the frame pivotably about a vertical pivoting axis and has a recess open towards the pivoting axis, the rear pivoting leg preferably being fork-shaped in the region of the recess.
  • the fork depth can be less than, more than, or substantially half the length of the rear pivot leg.
  • the support device according to the invention is not only suitable for extending the support lengths, e.g.
  • the front swivel legs 10 shown are designed as single telescopes, these fork depths would not be sufficient to accommodate the parts of the retracted telescopic sections 16 that protrude backwards beyond the swivel sections 14 . Due to the fact that the front pivoting legs 10 are designed according to the invention as multiple telescopic legs and have several (here: two) telescopic stages, the recesses 18 can be smaller, which gives the rear pivoting legs 12 greater rigidity.
  • the support device according to the invention is therefore also suitable for very large/heavy truck-mounted concrete pumps.
  • the machine components or add-on parts mentioned can be, for example, control blocks, switch cabinets, storage space, but also any other components. These can be mounted on the frame 26 .
