While suspending the work platform 11 by the crane during rubble disposal work, manipulators 20 suspended by a plurality of lines of respective traverse devices equipped on a work floor lower surface of the work platform 11 and attachments are operated. At the time, a suspending state is corrected so that the work platform 11 keeps a horizontal state according to a change state of load balance of leg parts 12 of the work platform 11. Then, rubble 4 (concrete mass 6 and reinforcing bars 7) accumulated inside the building is parted and crushed by the plurality of manipulators 20. |
