CAT 320 B

Cat 3066T is a six-cylinder mechanical direct injection engine without exhaust after-treatment. It does not require low-quality diesel. The spare parts market has a large supply and the maintenance cost is extremely low. It differs from 307D Mitsubishi and 312D/315D four-cylinder Caterpillar machines. This is a classic 20-ton model. It has strong hydraulic power and is suitable for crushing, earthwork, and heavy-duty mining conditions. It is equipped with original crusher pipe lines as standard. The thickened X-shaped frame and heavy-duty outriggers are durable and sturdy. There is a large second-hand circulation volume and a high preservation rate. The extended chassis 320BL has a larger ground contact area for the tracks, making it less prone to getting stuck on muddy and soft ground, and has a greater self-weight for more stable lifting. The combined fuel consumption is 11–14L/h. Compared to the new electronic injection models, the fuel consumption is higher, but there are no faults caused by after-treatment blockages.
