TURNTABLE STRUCTURE FOR BACKHOE

PURPOSE: To easy inspect valve groups by connecting a frame along the outer side of a swing frame in the state that a space open to the outer side is formed between the frame and the bottom plate of the swing frame and making a space blocking side plate freely removable. CONSTITUTION: A step mounting frame 3a is fixed and connected to the upper ends of supporting legs 3A standingly fixed to the outer periphery of the bottom plate 3C of a turntable at preset spaces, ranging over a rear frame which partitions a supporting plate for mounting a backhoe device, a valve room and an engine room along the outer side of the turntable. A peripheral side wall 3D is fixed and connected to the rear side of the step mounting frame 3a ranging from the step mounting frame 3a to the bottom plate 3C. An opening 3E ranging from the front face to the side face is blocked by a side plate 3F L-shaped in a plan view in a removable manner. When the side plate 3F is removed, the peripheral side wall of the turntable is open ranging from the front face to the side face to easily inspect valve 8 groups.
