Komatsu D575A
The Komatsu D575A is a tractor crawler available as a bulldozer/ripper, the D575A-3, or as a dedicated bulldozer, the D575A-3 SD Super Dozer. Equipped with a standard blade, both versions are capable of moving of material per pass although the D575A-3 SD Super Dozer is capable of moving of material per pass if equipped with an optional blade. The D575A-3 can dig to a maximum depth of using its single shank ripper.
Currently the largest bulldozer in production, the D575A has been produced by Komatsu Ltd. in Osaka, Japan since 1991. Surface mine operators in the United States, Canada and Australia are the primary users of the D575A, although it is sometimes used in heavy construction applications.
==Development==
Komatsu first showed a bulldozer prototype, the D555A, to the public at the Conexpo equipment exhibition in Houston, Texas in 1981. Due to economic conditions at the time, development was stalled for much of the 1980s. A successor to the D555A prototype, the D575A-2 SR Super Ripper, began field testing in North America in 1989, and full production began in 1991. The D575A-2 SR Super Ripper was joined by the D575A-2 SD Super Dozer in 1995 when the first D575A-2 SD Super Dozer was purchased and placed into service by the Princess Beverly Coal Co. in Cabin Creek, West Virginia. The current model, the D575A-3 SD Super Dozer was introduced in 2001.
