HYDRAULIC PIPING STRUCTURE OF SWING TYPE WORKING VEHICLE

摘要

PROBLEM TO BE SOLVED: To provide the layout structure of a hydraulic hose in a swing type working vehicle structured not to project a hydraulic pipe outward when swinging right and left while allowing a boom to sufficiently rotate to the back face side and an arm to sufficiently be bent to the ventral side of the boom to allow the small swing of a working machine. SOLUTION: In the swing type working vehicle, a piping part H4 of the hydraulic pipe at the back face of the boom 4 is recessed to the back face side of the boom 4 and bent toward the ventral side near the interference position of the boom 4 and a cabin 2a. A clearance between the cabin 2a and the boom 4 is thereby enlarged to avoid an interference and to ensure a backward rotating angle of the boom 4. COPYRIGHT: (C)2005,JPO&NCIPI
