Definitions

  • the invention relates to a mobile implement, particularly for demolition work suitable is.
  • Demolition excavators which have a demolition tool, e.g. a Demolition shears, wear.
  • the boom has two or more against each other swiveling sections to the height at which the demolition tool works, is determined by the angular position of the two sections: Demolition tools work at great heights, then the upper section of the Outrigger with the swung up lower section an obtuse angle. Should the demolition tool work at a lower height, then the upper section pivoted downwards relative to the lower section. But that’s how it works Tool tipping moment increased. This creates the risk that the Tool tipped over. This danger can be caused by swiveling the lower one back Section of the boom can only be counteracted to a limited extent. Such demolition excavators therefore have only a limited working area in which they work stably can. You need a heavy chassis that can prevent tipping.
