A grounding place variable outrigger for a wheel excavator provides optimal stability concerning the task of excavator regardless of the direction of work because the grounding place of the float of leg is changed. A grounding place variable outrigger for a wheel excavator comprises a frame(10), an arm(20) whereof one end is connected to the frame and is permitted to rotate around the perpendicular shaft to the ground, and a leg(30) with a float(40) which is connected to the other end of the arm. According to rotation of arm, the grounding place of float is variable. The arm rotates with a arm tilting cylinder(70). One end of the arm tilting cylinder is connected to the arm and the other end is connected to the frame. The arm is connected to the frame and is permitted to rotate around the arm tilting hinge point. |
