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.
- Pin Grabber: Offer fast, secure attachment changes and are compatible with a wide range of tools. Ideal for operators who need flexibility on the job site, they allow switching between buckets, hammers, and grapples. Features a redundant locking system to keep your attachments in place and protect them from damage.
- CW Quick Couplers: Rugged, wedge-style quick couplers built to increase the utilization of your excavator. Designed to fit your machine and application needs, Caterpillar® offers a series of CW couplers in mechanical and hydraulic versions. Ideal for contractors who prioritize a strong, simple locking system for frequent attachment changes.
- S-Type Couplers: A pin grabber-style dedicated coupler, S-Type Couplers feature a narrow, lightweight design for improved performance. They offer precision, flexibility, and are ideal for fleets needing consistent attachment interchangeability.
- Hydraulic Connecting S-Type (HCS) Couplers: HCS Couplers offer automatic hydraulic connection with the compact, low-profile design of the S-Type. With advanced functionality such as full hydraulic and electronic connection, hydromechanical attachments are connected and ready to operate in seconds.
- Performance Hammers: Built for high-demand applications, performance hammers deliver maximum impact energy and fast cycle times for breaking concrete, rock, and asphalt. Ideal for heavy-duty demolition, quarrying, and production environments where speed and power are critical.
- GC S Hammers: Simplified, silenced models designed for noise-sensitive environments. They maintain solid performance while reducing sound levels, making them ideal for urban job sites, residential areas, and regulated zones. Ideal for site prep, light demolition, foundry and quarry applications.
- Mulchers: Ideal for forestry and agriculture applications. Mulchers clear land and manage vegetation by shredding brush, trees, and undergrowth into fine mulch. Their high-speed rotors deliver fast, consistent results, with interchangeable teeth to suit different materials and desired final mulch size.
- 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. 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.

Refer to guidelines for successful application. Please consult your Cat dealer or “Caterpillar Machine Fluids Recommendations” (SEBU6250) for details.
- Auto Engine Speed Control reduces unnecessary fuel burn and greenhouse gas emissions by allowing the engine to automatically go into idle mode when the machine is not working.
- Extended maintenance intervals reduce downtime and decrease the amount of fluid and filters that are replaced over the machine's life.
- Cat® VisionLink displays the CO2 emissions for monitored assets, calculated by fuel type for the Runtime Fuel Burned each day in a selected date range.
- 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).
