• Make service work easier and safer with optional inspection lighting. With the flip of a switch, lights will illuminate the engine, pump, battery, and radiator compartments to enhance visibility.

    
• Start the engine with a push button; use a Bluetooth® key fob, or the unique Operator ID function.

    

• Program each joystick button, including response and pattern, using Operator ID; it will also remember climate control fan and radio settings.

    

• Navigate quickly on the standard high-resolution 203 mm (8 in) touchscreen monitor or with the aid of the jog dial control.

    

• Continuously improved user interface allows for intuitive navigation, minimizing performance interruption with the easy-to-use touchscreen menu.

    

• Use the in-monitor QR code to learn about machine and technology features through a full suite of “how-to” videos.

    

• Protect your hammer tool from overheating and rapid wear. Auto hammer stop warns you after 15 seconds of continuous firing and then automatically shuts it off after 30 seconds – all to extend the tool’s service life.

    

• Not sure how a function works or how to maintain the excavator? Always have the operator’s manual at your fingertips in the touchscreen monitor.

    
• The Comfort cab has a wide seat that adjusts for operators of all sizes.

    

• Control the excavator comfortably with easy-to-reach controls all located in front of you.

    

• Standard automatic climate control keeps you at the right temperature all shift long.

    

• Stow your gear with plenty of in-cab storage beneath and behind the seat, overhead, and in the consoles. A cup holder, document holder, bottle holder, and coat hook are also provided.

    

• Use the standard radio’s USB ports and Bluetooth® technology to connect to personal devices.

    
• VisionLink™ provides actionable data insights for all assets – regardless of fleet size or equipment manufacturer.* Review equipment data from your desktop or mobile device to maximize uptime and optimize assets. Equipment management features provide up-to-date asset tracking of your entire fleet. You can track asset location, operating hours, fuel level, health issues, and overall utilization. Monitor equipment health with fault codes, fluid analysis, and inspection due dates. It’s all about making informed, data-based decisions to help reduce operating costs. Productivity management features enable you to analyze overall job site performance. You’ll be able to track tonnage moved, production targets, and payload, as well as Grade 3D and compaction data. These vital metrics help you to reduce costs and improve jobsite operational efficiency.

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.

    

• 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.

    

• 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.

Cat® attachments are engineered to maximize your excavator’s productivity, helping you get more work done with greater efficiency and confidence.
