Bulldozers are earth-moving machines capable of excavating, transporting, and abandoning rock and are widely used in open pit mines. For example, it is used to construct waste dumps, flatten automobile dumping sites, pile up scattered ore rock, flatten work flats and construction sites. It is used not only for auxiliary work but also for major mining work. For example: stripping and mining of sand deposits, haulage and boosting of scrapers and plows, and other earth-moving machinery to reduce the height of stripping steps when there is no transport mining method.

Bulldozers can be classified into two types: track-type and tire-type. Track-type bulldozers have large traction, low ground pressure (0.04 to 0.13 MPa), and strong climbing ability, but their running speed is low. The tire-type bulldozer has high running speed, flexible maneuverability, short working cycle time, convenient transportation and transfer, but low traction, and is suitable for situations where the work site and the field work are frequently changed.

Can be divided into general-purpose and special-purpose two kinds. General-purpose models are produced according to standards and are widely used in earth and stone works. Dedicated for specific conditions, there are wetland bulldozers and marshland bulldozers, amphibian bulldozers, underwater bulldozers, cabin bulldozers, driverless bulldozers, high prototypes and highs that use triangular wide track shoes to reduce ground pressure. Bulldozers operating under wet conditions.

Bulldozers use mechanical transmissions or hydromechanical transmissions with hydrodynamic torque converters. A few hydraulic transmission systems are also used.
