It is comprised with the cylinder 794 for operation.

Next, an example of the dismantling process work by one embodiment of the dismantling work machine of this invention mentioned above is demonstrated using FIG.
FIG. 5 shows an example of performing an operation of separating the aluminum window frame A incorporated in the wooden frame W from the wooden frame W according to one embodiment of the demolition work machine of the present invention.
First, a part of the aluminum window frame A incorporated in the wooden frame W is cut with an appropriate cutter. After positioning the dismantling work machine of the present invention on the wooden frame W in this state, the first work arm 6 is operated and the wooden work W is gripped by the first work tool 67. Thereby, the wooden frame W incorporating the aluminum window frame A is in a fixed state.

  Next, the swinging device 8, the rotating device 9 and the second working arm 7 are driven and operated, and the tip of the second working tool 79 is made of the aluminum window frame A incorporated in the wooden frame W described above.
