Cummins KTA50-C2250 Engine is a high-power, highly reliable diesel engine designed for heavy-duty mining machinery. Below are its common application scenarios and compatible equipment types:
1. Mining Dump Trucks (rigid/articulated)
- Ultra-large mining trucks: Suitable for dump trucks with a payload capacity exceeding 150 tons, such as:
- Terex Unit Rig MT6300 (configuration verification required)
- BelAZ 7530/7531 series (compatible with certain models)
- Komatsu 930E (typically uses Cummins QSK series, but custom versions may integrate KTA50)
2. Large Hydraulic Excavators
- Ultra-large excavators: For models with bucket capacity exceeding 20 cubic meters, such as:
- Liebherr R 9800 (custom power configuration required)
- Caterpillar 6090 FS (usually equipped with Cat engines, but modified versions may adapt KTA50)
3. Mining Drills
- Open-pit drilling equipment: Suitable for high-torque rotary blast hole drills, e.g.:
- Atlas Copco Rotary Blast Hole Drills (e.g., PV-271 series)
- Sandvik DR Series Drills
4. Large Loaders
- Wheeled/tracked loaders: For ore-handling equipment, such as:
- Komatsu WA1200 (wheeled loader; power configuration verification required)
- Caterpillar 994K (typically uses Cat engines, but special retrofits may adapt KTA50)
5. Bulldozers and Graders
- Large tracked bulldozers: E.g., Komatsu D475A (custom configuration required; typically equipped with Komatsu engines).
Key Considerations
- Compatibility verification: Specific compatibility depends on OEM designs. The Cummins engine may be offered as an optional or customized solution.
- Environmental requirements: The KTA50-C2250 operates well in high-temperature, dusty mining environments but requires regular air and fuel filter maintenance.
- Power matching: With 1,600 HP (~1,193 kW), it is ideal for ultra-heavy machinery, but transmission systems must align with engine performance.
Note: Equipment compatibility and configurations may vary based on manufacturer specifications and custom engineering solutions.
