HYDRAULIC PIPING STRUCTURE FOR CONSTRUCTION MACHINE

摘要

PROBLEM TO BE SOLVED: To simplify assembly of a hydraulic hose in a construction machine equipped with a balanced-lever lift control box. SOLUTION: A pilot hose 21 is suspended from a remote control valve 15 operated by an operation lever 13 and pulled out from a control box 14 and is bent in the middle of a pipeline going to the control valve, and its bent portion is displaced when the control box 14 is lifted by the balanced-lever. In this way, the up-down motion of the pilot hose 21 can be absorbed.
