TRACK EXECUTION MACHINE FOR EXCAVATING BALLAST MATERIAL OF TRACK

摘要

PROBLEM TO BE SOLVED: To change the place of an excavation chain from the place of transport (an inoperative place) for relocation to the place of operation quickly at comparatively low structural cost by improving a track execution machine. SOLUTION: The track execution machine 1 is constituted as a cleaner between sleepers, in which a ballast scraping-out instrument 18 has a plate-shaped scraping-out tool 17 capable of being intruded between the sleepers and being extended in the longitudinal direction of a machine. The height of the scraping- out tool 17 can be adjusted within the range of the height of at least 65cm from the place of transport for relocation to the place of operation relatively to a support frame fixed onto a machine frame 3 at that time.
