CAT D8 Bulldozer Specification or Parts Details

The CAT D8 bulldozer performs outstandingly in construction operations, relying on the excellent performance of its components. Its engine serves as the core power source, adopting the Caterpillar CAT 3406C TA engine. With a large displacement of 14.6L, a cylinder bore of 137mm and a stroke of 165mm, it can output a power of 228kW, easily handling complex working conditions and ensuring the efficient operation of the equipment.

The transmission system is extremely sophisticated, with multiple gears set. The speed of the first gear is 0 - 3.5 km/h, suitable for fine operations such as trench excavation, allowing for precise control; the speed of the second gear is 0 - 6.2 km/h, balancing efficiency and control, and is suitable for regular earth - moving work; the maximum speed of the third gear reaches 0 - 10.8 km/h. When moving over long distances or working in open areas, it can move quickly, improving work efficiency.

In addition, the hydraulic system ensures the stable operation of working devices such as the bulldozer blade. All components work in coordination, making the CAT D8 bulldozer a reliable partner in construction projects and creating greater value for enterprises.
