In the first aspect, the scrap 9 is loaded on the scrap loading / moving vehicle 1 by a tow truck at the (a side) in FIG. After the loading, the scrap loading mobile trolley 1 is moved into the dust collection building 3, and then the shutter 8 is closed. Cutting is
Since the self-propelled gas cutting device 2 that travels on the gas cutting device traveling rail 7 is used, the size of the building is set to a space that can accommodate the scrap loading and moving vehicle 1.
Cutting work can be performed regardless of the weather such as wind and rain. Dust collector 4
Is used for the purpose of collecting fumes and dust at the time of cutting, and for preventing the temperature inside the dust collection building 3 from rising. 10 is an exhaust fan.
