PROBLEM TO BE SOLVED: To easily attach an accelerator lever, an unloading lever, a selector valve, and a selector lever to a slewing table and reduce the production steps for assembling members. SOLUTION: In this slewing work machine, a dozer is disposed at the front of a laterally extensible lower structure. A work device is supported on the slewing table on the lower structure. An operator's seat is installed on the slewing table. An operation box having a steering lever for steering the work device is installed at the front of the operator's seat on the slewing table. A support frame is vertically installed on the slewing table at the side of the operator's seat. The accelerator lever for controlling the rotation of an engine and the unloading lever for disabling the steering of the work device by the steering lever are installed, apart from each other in the longitudinal direction, on the support frame at the side of the operator's seat. The selector valve for selecting between the vertical movement of the dozer and the extension/retraction of the lower structure as well as the selector lever for operating the selector valve are installed under the accelerator lever and the unloading lever of the support frame.
