PROBLEM TO BE SOLVED: To smoothly move a working machine by providing a vehicle body, a running device, and cables moving wires by means of winches fitted to the vehicle body and cable devices fitted to fixed bodies. SOLUTION: Fixed bodies are provided on the right and left parts of the upper part of a part position forming surface of slope. Next cable devices are fitted to the fixed bodies. A working machine main body 1 is positioned on the lower part of the part position, and wires 49A are taken out from a pair of winches 14A, and fitted to the cables of the cable devices. When the surface of slope is formed in this condition, a crawler 3 is rotated while operating the winch 14A to wind up the wire 49A. Next cutting-off and excavation are executed while moving the main body upward. Works in the right and left directions are performed by moving the cables right and left so as to position the main body 1 in the suspending condition of the wires 49A of the winches 14A positioned in the rectilinear conditions from the cables. Hereby, the work can be safely executed without casting a large burden on the wires. |
