History and service record of D8T

  • The D8 name goes back to 1935. The D8 nameplate began as the RD8 in 1935, a tractor that was immediately popular for its balance of size and power, and a completely redesigned D8L followed in 1981. Iron Profile: the Caterpillar D8 through history, Classic Construction Models.
  • Bigger blade option. Caterpillar's CONEXPO 2017 release for the D8T describes a 13.4 yd3 (10.3 m3) Semi-U blade with 19 percent more capacity than the standard blade, which it says lifts productivity by up to 13 percent. New Cat D8T dozer features, OEM Off-Highway.
  • Performance cutting edges. The same release describes patented Performance Cutting Edges that Cat says raise blade load mass by up to 25 percent and reduce skating in moderate rock or hard or frozen ground. New Cat D8T dozer features, OEM Off-Highway.
  • Options added for maintenance and remote work. Powered Bottom Guards for clean-out, a fully suspended Heavy Duty Extended Life Undercarriage for high-abrasion sites, and a ready-for-remote-control COMMAND for Dozing build are listed as new D8T options in that release. New Cat D8T dozer features, OEM Off-Highway.
