The Caterpillar D8T is a large crawler dozer designed for heavy earthmoving, mining support, land clearing, and site preparation. It is part of Caterpillar's D8 series and is commonly used in applications that require high drawbar pull, blade capacity, and durable undercarriage performance. The D8T is typically equipped with a Caterpillar diesel engine, hydrostatic or powershift drivetrain depending on configuration, and a sealed, lubricated track system for improved service life. Common attachments include straight, semi-U, and coal blades, plus single-shank or multi-shank rippers. The model is used in construction, quarrying, forestry, and material handling operations.
