HYDRAULIC PIPING ARRANGEMENT STRUCTURE FOR CONSTRUCTION MACHINE

摘要

In the laying of hydraulic piping leading from a control valve to a hydraulic actuator of a front working machine, the space for laying the piping is reduced and a problem such as oil leakage from a connector joint section is eliminated. A hydraulic hose (22) for a front working machine, which hose leads from a control valve (20) to the front working machine, is laid so as to run from below the control valve (20), pass through an opening (15b) made in a supporting frame (15L), reach a space (S) formed between right and left supporting frames (15R, 15L), pass through a through-hole made in a coupling plate (17) covering the space (S), and then reach the front working machine. Further, a holding member (23) for supporting the hydraulic hose (22) is attached to the through-hole in the coupling plate (17).;COPYRIGHT KIPO & WIPO 2010
