PROBLEM TO BE SOLVED: To provide a hydraulic piping structure for a construction machine, which is constructed by simplifying hydraulic pipes connecting a hydraulic source of a main body to a pair of hydraulic cylinders of an operating attachment, to thereby reduce the number of component parts for pipe arrangement and pipe connecting portions. SOLUTION: The construction machine is formed of the equipment main body and the operating attachment mounted on the main body in a derrickable manner by means of the hydraulic cylinders 12A, 12B. According to the construction equipment thus formed, the pipes connecting the hydraulic source of the main body to the hydraulic cylinders 12A, 12B consist of a main body-side pipe 41 formed of a flexible hose connected to the hydraulic source of the main body, and cylinder-side pipes 42, 43 connected to the hydraulic cylinders 12A, 12B. Further, the main body-side pipe 41 is branched by a branch joint 51 attached to the tip thereof, and the cylinder-side pipes 42, 43 are connected to the branch joint 51, whereby the main body-side pipe 41 is branched and connected to the hydraulic cylinders 12A, 12B.
