Abstract: A track chain member (700) comprising a shoe member (702) defining a track chain traveling direction (T) and a lateral direction (L), the shoe member (702) further defining a first lateral end (703), a second lateral end (705), and a ground engaging surface (740) spanning from the one end (703) to the other end (705); wherein the shoe member (702) further defines a first side void (756) proximate the first lateral end (703), a second side void (705) proximate the second lateral end (705), and the first side void (756) terminates a first predetermined distance (760) from the first lateral end (703) and the second side void (758) terminates a second predetermined distance (762) from the second lateral end (705).

Abstract: A track chain assembly (100) comprises a plurality of interlocking track chain members (500) wherein each track chain member (500) defines a track chain traveling direction (T), a lateral direction (L) perpendicular to the track chain traveling direction (T), and includes a shoe member (502) defining a shoe width (W502) along the lateral direction (L); and a first track pad member defining a first track pad maximum width along the lateral direction, and a second track pad member defining a second maximum track pad width along the lateral direction, wherein a ratio of either track pad maximum widths to the shoe member width ranges from 1:4 to 3:4.

Abstract: A track chain member (400) comprises a shoe member (402), and a first rail member (404) extending from the shoe member (402), wherein the first rail member (404) defines a track chain traveling direction (T, 114) and a lateral direction (L) generally perpendicular to track chain traveling direction (T, 114), a first support surface (406) extending generally in both the track chain traveling direction (T, 114) and the lateral direction (L) defining an outer lateral extremity (408), and a first crest shaped member (410) disposed laterally adjacent the outer lateral extremity (408) of the first support surface (406).
