Incredible Power, Durability and Versatility.
More Comfort – More Performance – More Versatility
-
Smooth Operating Performance
The dedicated hydrostatic swing circuit regenerates swing break energy and independently manages cylinder oil flow for proven operating performance.
-
Track Production from a Single Shift up to 30 Days
Onboard Cat Payload weighs loads on the go to help meet cycle targets and helps prevent overloading or underloading trucks.
-
Ultimate Operator Comfort
Both cab options - Deluxe and Premium - are equipped with adjustable and optimally shaped seats for healthy support, automatic climate control, USB charging ports, Bluetooth® technology, and plenty of in-cab storage.

| Note (1) | Net power advertised is the power available at the flywheel when the engine is equipped with fan, air intake system, exhaust system, and alternator with engine speed at 1,700 rpm. Advertised power is tested per the specified standard in effect at time of manufacture. |
| Note (2) | ¹Cat diesel engines are required to use ULSD (ultra-low sulfur diesel fuel with 15 ppm of sulfur or less) or ULSD blended with the following lower-carbon intensity fuels** up to: 20% biodiesel FAME (fatty acid methyl ester)* or 100% renewable diesel, HVO (hydrotreated vegetable oil) and GTL (gas-to-liquid) fuels.Refer to guidelines for successful application. Please consult your Cat dealer or “Caterpillar Machine Fluids Recommendations” (SEBU6250) for details. * Engines with no aftertreatment devices can use higher blends, up to 100% biodiesel (for use of blends higher than 20% biodiesel, consult your Cat dealer).** Tailpipe greenhouse gas emissions from lower-carbon intensity fuels are essentially the same as traditional fuels. |
