Kind Code:
B2
Abstract:
To improve assembly workability of a clamp device in a clamp device in which a hydraulic piping is easily fixed on an outside face of a work arm.SOLUTION: A lower clamp 22 for a hydraulic piping of a clamp device 20 is temporarily secured on a pedestal 21 by inserting first fixing bolt 25 through a bolt insertion hole 22c and screwing it into a screw hole 21A of the pedestal 21. Thus, when second fixing bolts 24 are inserted through bolt insertion holes 23C,23D,22D,22E of an upper clamp 23 for a hydraulic piping and the lower clamp 22 for a hydraulic piping and screwed to screw holes 21B,21C of the pedestal 21, the upper clamp 23 for a hydraulic piping can be prevented from floating with respect to the lower clamp 22 for a hydraulic piping and the pedestal 21. A fastening work of the second fixing bolts 24 and an assembly work of the clamp device 20 can be easy.SELECTED DRAWING: Figure 3
