Engine and Powertrain
- Powered by a robust Cummins QSK19 six-cylinder, turbocharged, aftercooled diesel engine.
- The engine delivers a gross power of up to 560 hp (418 kW) and net power approximately 515 hp (384 kW).
- Engine displacement of 19 liters delivers high torque, around 2,379 Nm (1,755 lb-ft), at 1,300 rpm.
- Emission standard compliance to US EPA Tier 3 and EU Stage IIIA regulations.
- Variable speed, hydraulically driven suction-type cooling fan reduces fuel consumption by up to 5%.
- Equipped with a ZF 4WG-310 power shift transmission offering 4 forward and 3 reverse speeds.
- Maximum travel speed up to 10.6 mph (17 km/h) providing efficient site mobility.
- Heavy-duty tracked undercarriage with a track gauge of 90 inches and 7 carrier rollers per side.
- Track shoe width typically 30 inches with ground pressure around 21.8 psi.
- Standard blade options include Semi-U, Full-U, and specialized Coal blades with capacities ranging from 24.3 to 52 cubic yards (18.6 to 39.8 cubic meters).
- Blade height around 7 ft 4 in to 8 ft 2 in depending on the model.
- Maximum blade lift height approximately 5 ft.
- Rippers offered with 1 to 3 shanks extend machine versatility in tough ground conditions.
- Spacious ROPS/FOPS certified cab with air conditioning and ergonomic suspension seat reduces operator fatigue.
- Multi-function joystick controls provide responsive blade and steering input.
- Enhanced visibility is bolstered by cab-mounted lighting and rearview camera options.
- Overall height approximately 13 to 14 feet depending on cab and exhaust configurations.
- Length with blade varies between 26 and 34 feet with attached ripper.
- Operating weight ranges around 200,000 lbs (90,700 kg).
- Weight distribution optimized for traction and stability in severe terrain.
- Power Shift Transmission: Gear system enabling smooth shift change under load.
- Turbocharged and Aftercooled: Engine features increasing power and efficiency by forcing extra air and cooling it before combustion.
- Ground Pressure: Measure of pressure exerted on the ground by the machine tracks.
- ROPS/FOPS: Safety standards for roll-over and falling object protection structures in cabs.
- Carrier Rollers: Components supporting the upper run of the crawler track, protecting track and undercarriage.
