Manufacturer: Caterpillar ➔
Model: D8T ➔

Caterpillar D8T is a large crawler dozer designed for heavy earthmoving, mining support, land clearing, and site preparation. It uses a Caterpillar diesel powertrain, hydrostatic or powershift-style drivetrain depending on configuration, and a wide undercarriage for traction and stability on rough terrain. The D8T is commonly equipped with a straight blade, semi-U blade, or other dozer attachments for grading, pushing, and bulk material handling. It is used in construction, quarry, forestry, and road building applications where high drawbar pull and durable undercarriage performance are required. The model is known for serviceability, operator visibility, and compatibility with grade control systems.
