Latest Features

Machine Setup Simplification

At the touch of fingertips and navigating user-friendly icons, the latest operator oriented User Interface (UI) maximizes uptime and gets crews to work without delay. From re-ordering work tool lists to creating new work tool combinations as needed, operators can quickly set up machines and easily access information.
The interface allows operators to maintain accuracy and makes the most of every second of their shift. Adding the ability to input couplers and attachments into the system makes setting up work tool combinations highly efficient by significantly reducing calibration time. It also eliminates the need to measure up again when changing Cat® work tool attachments and makes it manageable for a single person to check and adjust for bucket wear.

Cat Payload and Advanced Payload*

Cat Payload provides operators with on-the-go weighing to help them hit load targets and avoid overloading, underloading, or misloading materials. Advanced Payload is a system upgrade that offers expanded features and capabilities, including custom tags, daily totals, and electronic ticketing. Combine Payload with VisionLink™** to analyze jobsites and individual assets for remote management of production targets and key metrics.

*Payload technologies are not legal for trade.
**VisionLink subscription required.

Not all features are available in all regions. Please check with your local Cat dealer for specific offering availability in your area. Build Number: 08D.

Attachments

Tackle your jobs with a complete Cat® solution. Cat attachments are not just accessories – they are essential tools that define what your machine can do. When you pair a Cat excavator with Cat attachments, you unlock a fully integrated system built for performance, durability, and efficiency. Whether you are clearing land, breaking concrete, or compacting soil, the right attachment transforms your excavator into a powerful, multi-purpose tool ready for any challenge. Depending on your project or application, you could benefit from excavator attachments such as

Buckets: Handle everything from digging and grading to cleanup and debris removal with your excavator. Caterpillar® offers general duty, heavy duty, extreme duty, and severe duty buckets, as well as specialized designs for ditch cleaning, rock, and finishing work. Reinforced edges and wear-resistant materials ensure long-lasting performance in tough conditions.
Couplers (HEX): Cat® couplers for excavators enable fast, secure attachment changes, without the need to leave the cab. From Pin Grabbers to hydraulic quick connect options, couplers help reduce downtime, boost jobsite efficiency and promote versatility by allowing multiple machines to share a common attachment inventory.
Hammers: Break concrete, rock, and steel with up to 1,000 blows per minute. Built for high-production demolition, quarrying, and construction, they offer powerful impact energy and consistent performance. Their durability and low-maintenance design make them essential for demanding breaking applications.
Multi-Processors: A versatile tool for demolition, equipped with interchangeable jaws to handle concrete, steel, and rebar. Multi-Processors combine cutting, crushing and pulverizing capabilities in one attachment. Their modular design maximizes efficiency across a range of job site demands.
Demolition and Sorting Grapples: Tackle larger debris or precisely sort materials into piles. These grapples are engineered for accuracy in demolition and material sorting, handling concrete, rebar, wood, and mixed debris. High clamping force and agile movement make them ideal for primary and secondary demolition and recycling operations
Scrap and Demolition Shears: Rotating shears provide precision cutting for metal structures, pipes, rebar, and scrap, making them ideal for demolition and recycling. Their powerful jaws and fast cycle times ensure clean cuts and high productivity. Built for durability, they excel in heavy-duty steel processing.
Pulverizers: Built to crush concrete and separate rebar during demolition and recycling. With high crushing force and fast cycle times, pulverizers efficiently reduce material for easier handling. Primary models feature 360° bidirectional rotation and tackle structure teardown, while secondary models have a fixed jaw design and process debris after demolition.
Orange Peel Grapples: Built for scrap and bulk material handling, Orange Peel Grapples excel with irregular, heavy loads like metal, rock, and waste. Their hydraulic tines provide superior grip and penetration. High-capacity and continuous rotation are perfect for scrap yards and transfer stations. Caterpillar® offers these grapples with a choice of different shell designs and tine options suited to various applications.
Clamshell Grapples: Perfect for bulk material handling, dredging, and excavation of loose or semi-compacted materials like sand, gravel, and debris. Their dual-opening jaws allow for precise loading and unloading. High-capacity and controlled operation make them ideal for ports, recycling, and heavy civil projects.
Compactors (Vibratory Plate): Compact soil, sand, gravel and asphalt quickly and efficiently to create a stable foundation. Vibratory plate compactors deliver high-impact force and even coverage, reducing air pockets and improving surface integrity for trenching, roadwork, and patching.
Rotary Cutters: Get accurate, precise work with less noise and vibration. Cat® Rotary Cutters deliver high torque and precision for a range of applications: demolition, grinding, profiling, trenching, tunneling, and quarrying. Specifically designed for excavator-mounted use to handle heavy-duty materials like concrete, rock, and dense brush with ease.

Cat® attachments are engineered to maximize your excavator’s productivity, helping you get more work done with greater efficiency and confidence. Choosing the right attachment is not just about compatibility, it is about unlocking your machine’s full potential while avoiding equipment damage or safety risks. Connect with your Cat Dealer to find the optimal attachments for your specific machine and application needs.

Not all attachments are available in all regions. Contact your Cat Dealer for details.

Sustainability

The Cat® C9.3B engine meets U.S. EPA Tier 4 Final, EU Stage V, and Japan 2014 emission standards.
Cat diesel engines are required to use ULSD (ultra-low sulfur diesel fuel with 15 ppm of sulfur or less) and are compatible* with 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.
Auto Engine Speed Control helps reduce unnecessary fuel burn and greenhouse gas emissions by allowing the engine to automatically go into idle mode when the machine is not working.
Cat Grade technologies combine advanced guidance with optional automated machine control helping you reach grading targets while reducing fuel burn and greenhouse gas emissions by improving efficiency, job site productivity, and accuracy.
Cat® Payload for excavators provides on-the-go material weighing which helps reduce fuel burn by improving loading efficiency, job site productivity, and eliminating trips to the scale.
Cat® 2D E-fence keeps the front linkage within a predefined work area to avoid hazards such as traffic - not only helping keep personnel safe but also helps you avoid repairs, downtime, and costly job site fines.
Extended maintenance intervals not only reduce downtime but decrease the amount of fluid and filters that are replaced over the life of the machine.
Remote Flash minimizes downtime and maintenance time while keeping your asset running with maximum efficiency. Alerts for machine updates are sent virtually from your Cat dealer and updates can be deployed without a dealer technician needing to be onsite.

*While Caterpillar engines are compatible with these alternative fuels, some regions may not allow their use.
**Tailpipe greenhouse gas emissions from lower-carbon intensity fuels are essentially the same as traditional fuels.
***Engines with no aftertreatment devices are compatible with higher blends, up to 100% biodiesel (for use of blends higher than 20% biodiesel, consult your Cat dealer).
