An upper rotating frame mounted on a lower traveling body, and earth removal plates provided at the front and rear of the lower traveling body, and each drive cylinder of both outriggers and each driving cylinder provided on the upper rotating frame. In construction machinery, a hydraulic circuit is provided in which the upper swing frame side and the lower traveling body side are connected by a swivel joint between the hydraulic power sources, and the upper swing frame side of the hydraulic circuit is connected to the hydraulic power source via a control valve. The first to be
The pipe is connected to the port of the swivel joint, and the lower running body side of the hydraulic circuit is connected to the port of the switching valve material connecting the port and the cylinder for driving the earth removal plate. A third pipe line of a switching valve material which is branched from between the switching valve and the port in the second pipe line and connected to the driving cylinder of the outrigger, 1. An operating device for earth removal plates and outriggers for construction machinery, characterized in that a driver's seat provided in a frame is provided with an operating lever for operating the control valve and an operating lever for operating each switching valve. 2. The operating device for earth removal plates and outriggers for construction machinery as set forth in claim 1, wherein the operating lever for operating each switching valve also serves as a parking brake operating device.
