STRUCTURE FOR MOUNTING A HYDRAULIC HOSE ON HYDRAULIC CYLINDER FOR BLADE OPERATION

摘要

PROBLEM TO BE SOLVED: To provide a structure for mounting a hydraulic hose devised to change only a broken hydraulic hose even when it is broken in the middle of working by dividing the hydraulic hose to a hydraulic hose connecting part of the hydraulic cylinder for blade working from the hydraulic hose connecting part of a selector valve provided on a swivel joint in a revolving round barrel of a lower part travelling body in two pieces. SOLUTION: The hydraulic hoses are respectively installed between the hydraulic hose connecting part of the selector valve and a hydraulic hose connecting part of a hydraulic hose junction holding bracket and between the hydraulic hose connecting part of the hydraulic hose junction holding bracket and the hydraulic hose connecting part of the hydraulic cylinder for blade working by providing the hydraulic hose junction holding bracket on a blade elevating frame at a position equivalent to roughly the middle of the hydraulic hose connecting part of the selector valve provided on the swivel joint in the inside of the revolving round barrel of the lower part travelling body and the hydraulic hose connecting part of the hydraulic cylinder for blade working.
