PROBLEM TO BE SOLVED: To provide a scattering prevention device capable of preventing upward scattering of debris by a simple configuration, without making a scattering prevention sheet higher than necessary or requiring a work machine such as a juxtaposed crane, when a building is demolished.SOLUTION: An arm 15 of a working front of a demolition machine is provided with an attachment frame 26. A cover frame 33 is attached in such a manner as to be capable of longitudinally rotating by a hydraulic cylinder 41 on a pivot shaft 39 provided in the attachment frame 26. Cover materials 34-36 are attached to the cover frame 33. In an attitude in which the cover frame 33 is rotated forward, a crushing tool 19 attached to the arm 15 is covered with the cover materials 34-36 from an upper side thereof.SELECTED DRAWING: Figure 2 |
