Expect high fuel efficiency – more work per unit of fuel.
Match the excavator to the job with three power modes – Power, Smart, and Eco. Smart mode automatically matches engine and hydraulic power to working conditions, providing max power when needed and reducing power when it isn’t to help save fuel.
Auxiliary hydraulic options give you the versatility to use a wide range of Cat attachments, including the heaviest tools needed for demolition work.
Don’t let the temperature stop you from working. This excavator has a high-ambient capability of 52° C (125° F) and cold start capability of –18° C (0° F).
Advansys™ bucket tips increase production and lower costs with more tip life.
The Cat PL161 attachment locator is a Bluetooth® device designed to let users know where their attachments are across all worksites, reduce the number of lost attachments, and plan for attachment maintenance and replacement. The PL161 integrates easily into VisionLink® for full fleet management of machines and attachments from one smartphone or tablet dashboard to view location and tracking details.

Standard Cat Grade with 2D indicates depth and slope on the monitor with auditory alerts.
Cat Payload onboard weighing helps you achieve precise load targets to improve your operating efficiency. Pick up a load of material – with either a bucket or grapple – and get a real-time weight estimate without even swinging.
Combine Payload with VisionLink® and remotely manage your production targets. The monitor’s USB port lets you download results from one shift all the way up to 30 days of work, so you can manage your progress without needing an internet connection or VisionLink subscription.
Know the excavator’s exact position relative to GPS and GLONASS systems. The machine automatically compensates for excavator pitch and roll caused by sloping ground conditions.
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. Dashboards provide information such as hours, miles, location, idle time, and fuel utilization. Make informed decisions that lower costs, simplify maintenance, and improve safety and security on your jobsite.
VisionLink Productivity gathers and summarizes machine telematics and jobsite data from all your equipment – regardless of the manufacture.* View actionable information such as idle time, fuel burn, location, payload, load counts, total cycles, and more to improve machine efficiency, productivity, and utilization. Access data anywhere via a mobile, tablet, or desktop device - on or off the jobsite.
Remote Troubleshoot is a mobile application that allows your Cat dealer to perform diagnostic testing on your connected machine remotely to help ensure that issues are resolved quickly and with less downtime.
Remote Flash is a mobile application that allows you to update onboard software without a technician being present, allowing you to initiate software updates when convenient, increasing your overall operating efficiency.
The Cat PL161 attachment locator allows you to track attachments across all worksites, reduce the number of lost attachments, and plan for attachment maintenance and replacement. The work tool recognition feature automatically adjusts machine settings based on the selected tool.

*Data field availability can vary by equipment manufacturer.

The demolition cab comes with a deluxe heated seat and climate control.
Get in and out of the cab easier with the tip-up left console.
Control the excavator comfortably with easy-to-reach controls all located in front of you.
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 personal devices and make hands-free calls.

Start the engine with a push button; use a Bluetooth® key fob or the unique Operator ID function.
Program your power mode and joystick preferences using operator ID; the excavator will remember them every time you go to work.
Automatic hydraulic oil warmup gets you to work faster in cold temperatures and helps prolong the life of components.
Navigate quickly on the standard high-resolution 254 mm (10 in) touchscreen monitor or with the aid of the jog dial control.
Make moving the excavator much easier with Cat Stick Steer. Simply push a button and use one hand to travel and turn instead of both hands or feet on levers or pedals.
Need more lift during your shift? Auto heavy lift gives you 8% more power exactly when you need it for as long as you need it.
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.

Expect low maintenance cost with extended and synchronized service intervals.
Check hydraulic system oil and easily drain fuel system water and fuel tank water from ground level.
Track your excavator’s filter life and maintenance intervals via the in-cab monitor.
Change all fuel filters at a synchronized 1,000 hours. Oil and fuel filters grouped and located on right-hand side of machine for easy maintenance.
The air intake filter with pre-cleaner has high dust holding capacity.
The hydraulic oil filter provides improved filtration performance; anti-drain valves keep oil clean when the filter is replaced.
The high-efficiency hydraulic fan has an optional automatic reverse function to keep cores free from debris, eliminating the need for any operator interaction.
S·O·S^SM ports simplify maintenance and allow for quick, easy extraction of fluid samples for analysis.

The front windshield and top hatch are made with EN 356 P5A glazing for enhanced impact resistance.
The standard ROPS cab meets ISO 12117-2:2008 requirements.
Operator Protective Guards (OPG) enhances overhead safety.
A travel direction indicator helps operators know which way to activate the travel levers.
Enjoy great visibility with the help of narrow cab pillars, large windows, the standard parallel roof wiper and washer, and a flat engine hood design.
A ground-level shutoff switch stops all fuel to the engine when activated and shuts down the machine.
Rearview and sideview cameras are standard. Upgrade to 360° visibility and you’ll easily visualize objects and personnel around the excavator in a single view.
Serrated steps and anti-skid punch plate on the service platform help prevent slipping.
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.
Standard 2D E-Fence integrated right out of the factory prevents the excavator from moving outside of operator-defined set points.

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) 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.
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.
Don't waste fuel idling. Cat VisionLink® online fleet monitoring helps you manage idle time and reduce fuel burn and greenhouse gas emissions.
Extended maintenance intervals not only reduce downtime but decrease the amount of fluid and filters that are replaced over the life of the machine.

*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.
