NEW TRACK STRUCTURE & FEATURE 1) Adoption of wedge ring to the pin hold bore at bushing turn. As a result, man-hour can be shortened and parts reusable ratio can be increased. 2) Link guard and link shape change to avoid interference of pin ends and guards. effect: Pin press-fitting force can be reduced, and it reduce scuffing between pin and link effect: Pin end face wear can be eliminated, then it result man-hour reduction of pin end face maintenance and pin reusable ratio improvement. 3) Expanding of link and rollers tread width effect: Wear life on track link and rollers can be elongated due to surface pressure reduction.
4) Adoption of K-bogie which rollers following-up track link movement. effect: Elimination of track coming off, then rollers flange wear life can be extended. And riding comfort would be improved. - 2 - K- bogie NEW TRACK CURRENT TRACK Track Link tread roller Link Guard Wedge ring
