HIGH PERFORMANCE WITH LOW FUEL CONSUMPTION

High fuel efficiency ensures more work per unit of fuel.
The C9.3B engine and electrohydraulic system will power through all different types of material.
Auxiliary hydraulic options give you the versatility to use a wide range of Cat attachments, including the largest attachments needed for demolition work.
Achieve higher vertical reach up to 22 m (72'2") or 25 m (82'0") with a UHD boom.
Match the excavator to the job with three power modes – Smart, Power, and Eco. Smart mode automatically matches engine and hydraulic power to digging conditions, providing maximum power when needed and reducing power when it isn't to help save fuel. Power mode is maximum power all the time. Eco mode reduces engine speed and keeps it constant to reduce fuel consumption.
The high-efficiency hydraulic fan cools the engine on demand to help reduce fuel consumption; standard reverse function makes it easy to keep cores clean.

BOOST EFFICIENCY AND PRODUCTIVITY

Standard Cat Grade with 2D with a retrofit boom 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 with a retrofit boom. 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.
The stability monitoring system continuously informs operators of work tool position within the safe working range and warns when approaching the stability limit.
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 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.

*Data field availability can vary by equipment manufacturer.

RELIABLE IN TOUGH CONDITIONS

Reinforced booms, sticks, and frame make the machine more durable and built to last.
Standard high-ambient temperature capability is 52°C (125°F) with cold start capability at -18°C (0°F).
Auto hydraulic oil warmup gets you to work faster in cold temperatures and helps prolong the life of components.
Grease sealed between track pins and bushings reduces travel noise and prevents debris from entering to increase undercarriage life.
The sloped track frame prevents mud and debris accumulation, helping reduce risk of track damage.

SIMPLE TO OPERATE

Start the engine with a push button; use a Bluetooth® key fob or the unique Operator ID function.
Program each joystick button, including power mode, response, and pattern, using Operator ID; the machine will remember what you set each time you go to work.
Make moving the excavator much easier with standard 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.
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.

WORK IN COMFORT

Get in and out of the cab easily with the standard tilt-up left console.
Deluxe cab with premium seat offers a heated and ventilated seat for year-round comfort.
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 and in the consoles.
Use the standard radio’s USB ports and Bluetooth® technology to connect personal devices and make hands-free calls.

EASY MAINTENANCE

Long life fuel, oil, and air filters keep you working on the job longer.
Check the hydraulic system oil and easily drain fuel system water from ground level.
Track your excavator’s filter life and maintenance intervals via the in-cab monitor. The optional engine oil sensor tracks your oil levels to speed up your daily maintenance routine.
Change all fuel filters at a synchronized 1,000 hours. Filters are grouped together for easy maintenance.
The air intake filter with pre-cleaner has a high dust holding capacity.
The hydraulic oil filter provides improved filtration performance and anti-drain valves to keep oil clean when the filter is replaced.
The high-efficiency hydraulic fan has a standard automatic reverse function to keep cores free from debris, eliminating the need for any operator interaction.
Boost productivity with proactive service reminders. The Integrated vehicle health management system alerts the operator with step-by-step service guidance along with parts needed so you don't experience any unnecessary downtime.
S•O•S^SMports simplify maintenance and allow for quick, easy extraction of fluid samples for analysis.

SAFELY HOME EVERY DAY

The front windshield and roof window are made with P5A glazing for enhanced impact resistance.
A travel direction indicator helps operators know which way to activate the travel levers.
Enjoy great visibility in each swing direction and behind you with the help of smaller cab pillars and larger windows.
Standard Operator Protective Guards (OPG) protect the roof and front window in a demolition application while also maintaining visibility to the jobsite.
A ground-level shutoff switch stops all fuel to the engine when activated and shuts down the machine.
Rearview and right-hand-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.
Keep your excavator secure with Operator ID. Use your PIN code on the monitor to enable the push button starting feature.
Standard 2D E-Fence (swing) helps you avoid swinging into obstacles to the side of the machine such as live traffic and structures
Cat Lift Assist with retrofit boom helps you avoid tipping by letting you know if your load is within the excavator’s safe working range.

SUSTAINABILITY

The Cat® C9.3B engine emits equivalent to U.S. EPA Tier 3 and EU Stage IIIA.
Cat engines are compatible with diesel fuel blended with the following lower-carbon intensity fuels** up to: 100% 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.

*For use of blends higher than 20% biodiesel, consult your Cat dealer.
