Description

A construction machine according to the present invention includes a self-propelled vehicle body, a work device that is attached to the vehicle body so as to be movable up and down, and a work arm that is operated by an actuator, and the work for supplying and discharging pressure oil to and from the actuator of the work device. A plurality of fixed tube bodies extending along the length direction of the arm and fixed to at least one of the actuator and the work arm, and separately from the fixed tube body, along the length direction of the work arm And a flexible tube provided.
And in order to solve the subject mentioned above, the feature of the configuration adopted by the invention of claim 1 is a tubular body having a bolt insertion hole through which a bolt is inserted and a tubular body insertion hole through which a flexible tubular body is inserted. bracket and has and a U-bolt is provided for fixing the disposed across the fixed tube body the tubular body bracket is inserted into the bolt insertion holes of the tube bracket to the fixed tube, the flexible tube is that described above and configuration that is attached to a fixed tube while being inserted into the tube insertion holes of the tubular body bracket.
According to a second aspect of the present invention, the flexible tubular body is formed in a desired length dimension by connecting ends of adjacent tubular bodies in the length direction using a connecting adapter. The tube is configured to be attached to the tube bracket at the position of the connecting adapter.
According to a fourth aspect of the present invention, the fixed tube is disposed along a length direction of the working arm, and the flexible tube is disposed below the fixed tube, and the tube bracket. It lies in the configuration that is mounted and in a state of being suspended with respect to the fixed tube by.
