  Since the dismantling machines described in Patent Document 1 and Patent Document 2 perform work from a high place to a low place only by adjusting the length with a telescopic boom, the mobility and work radius of the boom itself are reduced. Therefore, the mobility of the lowered boom itself and the narrowed working radius are compensated by the movement of the dismantling machine.

  However, since the demolition work machine is heavy, it is necessary to reinforce the work floor with a temporary material so that the work floor can withstand the weight. Therefore, the wider the range of dismantling machine movement, the more temporary work will be required for reinforcement, and the longer the construction period and the higher the cost in the dismantling work that requires speed and safety. Issues to be addressed remain. In addition, this type of construction machine needs to be moved from the site to the site by placing it on the trailer bed, so it can be folded compactly during transportation, and the amount of overhang from the rear end of the trailer bed is small. It is requested.

  Therefore, with one construction machine, it is possible to perform dismantling work with less movement from work at high places to work at low places, and technical issues to be solved to make a structure with good transportability The present invention aims to solve this problem.
