PROBLEM TO BE SOLVED: To prevent a crane hook from striking against a window arranged at a soundproof box top plate of a mobile working machine for use in fixing the crane hook against a suspender.SOLUTION: A tray 32 is fixed to the rear surface of a top plate 42a of a soundproof box 40 at a position where a window 30 is formed, and a cavity 33 defined by the tray 32 is formed within the window 30. At the same time, the bottom surface of the cavity 33 is provided with an opening 34, so that a suspender fitting 22 oscillatably pivoted at the upper end of a suspender main body 21 can be protruded out of the soundproof box 40 through the opening 34. In this way, a crane hook is fixed to the suspender fitting 22 protruded out of the soundproof box 40 to enable the crane hook to be less easily struck against an opening edge 31 of the window 30, and then there can be prevented the generation of clearance to be an immersion path of rain water generated between the window 30 and a door 15 as a result of strain of the window 30 caused by the striking. |
