PROBLEM TO BE SOLVED: To facilitate maintenance work for hydraulic equipment and reduce the manufacturing cost of a revolving frame, by concentrating, in one place, paths of passage of a plurality of pilot hoses in the revolving frame and parts for insertion into a floor sheet. SOLUTION: In a revolving working machine, the revolving frame 4 is provided on a travel device 3 in such a manner as to be freely revolvable around a vertical shaft center; left and right paired control tables 43L and 43R having control levers 42L and 42R are separately arranged on both left and right sides of a driver seat 41 on the revolving frame 4; pilot valves 49L and 49R, which are housed in the respective control tables 43L and 43R, are connected to control valves 48 and 49 in the revolving frame 4 via the pilot hoses 50, respectively; and the pilot hoses 50 are combined into one group inside the revolving frame 4, and combined into two paths, that is, a first hose group 53 for one pilot valve 43L and a second hose group 54 for the other pilot valve 43R, which branch off from each other above the revolving frame 4 and below the driver seat 41.
