Title:
HYDRAULIC PIPE STRUCTURE FOR ATTACHMENT TO MOVABLE WORKING VEHICLE
Document Type and Number:
WIPO Patent Application WO/2012/148084
Kind Code:
A2
Abstract:
The present invention pertains to a hydraulic pipe structure for attachment to a movable working vehicle which supplies pressured oil to an attachment connection link cylinder or the like for easily attaching or detaching an attachment such as a bucket or the like which is a work instrument attached to one end of an arm which is mounted to a movable working vehicle such as a tractor or the like. More specifically, only a minimal part of an oil pressure supply hose is exposed to the outside with respect to the hydraulic pipe which supplies the pressured oil to the attachment connection link cylinder for easily attaching or detaching an attachment attached to one end of the arm. Therefore, the oil pressure supply hose is prevented from being damaged due to collisions with stones or obstacles during operation. In addition, the hydraulic pipe structure is simplified and thus manufacturing costs may be reduced or the like.
