PROBLEM TO BE SOLVED: To provide a piping structure of a front work machine capable of improving durability by reducing a burden to a hydraulic pipe caused by the rotational movement of the front work machine, by laying a pipe in conformity with a structure of the vertically rotating front work machine, by preventing the expansion of the whole width of the front work machine by the hydraulic pipe extended from the main machine side. SOLUTION: This piping structure of the front work machine is installed in a main machine via a bracket 7 as a rotational movement support part arranged on both left and right sides or one side of a hood arranged in a main machine front part. A hole part 20 for penetrating the hydraulic pipe 30 is arranged in a lift arm 11 being a structural member of the front work machine. COPYRIGHT: (C)2006,JPO&NCIPI |
