High Performance
The C9.3B engine generates more power than the 2020 model year 336 engine.
More power to the pumps, wider undercarriage, and heavier counterweight enable up to 10 percent more productivity.
Match the excavator to the job with three power modes – Power, Smart, and Eco. Power mode is maximum power all the time. 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. Eco mode reduces engine speed and keeps it constant to reduce fuel consumption
Boost Efficiency and Productivity
Boost productivity up to 45 percent with optional Cat Grade technology.
Optional 2D Grade indicates depth and slope on the monitor with auditory alerts.
Optional Grade Assist helps you stay on grade – simply and effortlessly – with single-lever digging.
Automatically stop excavator swing at operator-defined set points in truck loading and trenching applications with optional Swing Assist, which will help you use less effort and consume less fuel.
Optional Cat Payload on board weighing helps you achieve precise load targets to improve your operating efficiency. Pick up a load of material – with a bucket and thumb combination or grapple and clamshell attachments – 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.
Upgrade to Cat Grade with Advanced 2D and create and edit grade designs with ease on a second high-resolution 254 mm (10 in) touchscreen monitor.
Want a 3D system to improve your digging results? Caterpillar's new single antenna global navigation satellite system (GNSS) makes it easy by giving you visual and auditory guidance to grade. Plus you can create and edit designs on the touchscreen monitor while you’re on the job. If your application calls for a dual antenna system, it’s easy to upgrade.
Upgrade to our dual antenna GNSS for maximum grading efficiency. The system lets you create and edit designs on the touchscreen monitor while you’re on the job, or you can have the plan design sent to the excavator to make your work easier. Plus you get added benefits of avoidance zones, cut and fill mapping, lane guidance, and augmented reality along with advanced positioning capability.
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.
All Cat Grade systems are compatible with radios and base stations from Trimble, Topcon, and Leica.
Already invested in a grade infrastructure? You can install grade systems from Trimble, Topcon, and Leica onto the machine.
Remote troubleshoot connects you to a dealer service pro to help solve your problem and quickly get you to work.
Remote flash works around your schedule to ensure your machine’s software is up to date for optimal performance.
Standard Product Link™ provides location, machine hours, fuel usage, productivity, idle time, diagnostic codes, and other machine data on demand through VisionLink online interface, helping you improve jobsite efficiency with lower operating costs.
Built for Rugged Conditions
Reinforced structures ensure long-term durability in harsh environments.
Work up to 4500 m (14,764 ft) above sea level.
Standard high-ambient temperature capability is 52° C (125° F) with cold start capability at –18° C (0° F).
An optional battery-operated engine heater enables starting at –32° C (–25.6° F).
Auto hydraulic oil warmup gets you to work faster in cold temperatures and helps prolong the life of components.
Two levels of filtration protect the engine from low-quality diesel fuel.
Grease sealed between track pins and bushings reduces travel noise and prevents debris from entering to increase undercarriage life.
Work in Comfort
Choose between Essential and Deluxe cabs – both with automatic climate control.
Deluxe cab comes with heated seat to keep you warm and tilt-up left console to enable easy entry and exit.
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.
Use the standard radio’s USB ports and Bluetooth® technology to connect personal devices and make hands-free calls.
Simple to Operate
Start the engine with the push of a button; use a Bluetooth key fob or Operator ID passcode.
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.
Trouble cutting through tough material? Optional auto dig boost gives you an automatic power increase of 8 percent when you need it for better bucket penetration, shorter cycle times, and greater payloads.
Need more lift during your shift? Optional auto heavy lift gives you 8 percent more power exactly when you need it for as long as you need it.
Make moving the excavator much easier with optional 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.
Navigate quickly on the standard high-resolution 203 mm (8 inch) touchscreen monitor or available 254 mm (10 in) monitor.
Protect your hammer from overworking. Auto hammer stop warns you after 15 seconds of continuous firing and then automatically shuts it off after 30 seconds – all to prevent wear and tear on the attachment and excavator.
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.
Enhanced Safety
2D E-Fence prevents the excavator from moving outside of operator-defined set points; the system works with thumb and bucket combinations along with hammer, grapple, and clamshell attachments.
Cat Detect - People Detection helps protect the most valuable asset on any jobsite – people. The system uses smart cameras with depth sensors to provide the operator with visual and auditory alerts so he or she can take immediate action when a person is too close to the excavator.
The Rollover Protective Structure (ROPS) cab meets ISO12117-2:2008 requirements.
Enjoy great visibility with the help of narrow cab pillars, large windows, and a flat engine hood design.
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.
Optional Cat Lift Assist helps you avoid tipping by letting you know if your load is within the excavator’s safe working range.
A travel direction indicator helps you know which way to activate travel levers.
Enhance jobsite safety. Add a swing alarm to alert people when you're rotating from trench to stockpile and back again.
Keep your excavator secure with Operator ID. Use your PIN code on the monitor to enable the push button starting feature.
A ground-level shutoff switch stops all fuel to the engine when activated and shuts down the machine.
Serrated steps and anti skid punch plate on the service platform help prevent slipping.
A rearview camera is standard.
Easy Maintenance
Boost productivity with proactive service reminders. Our new 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.
Expect less maintenance cost due to 1,000 hour engine oil intervals.
Change all fuel filters at a synchronized 1,000 hours. Filters are grouped and located on right-hand side of machine for easy maintenance.
Check hydraulic system oil and easily drain fuel system water and fuel tank water from ground level.
The air intake filter with pre-cleaner has high dust holding capacity.
The hydraulic oil filter provides superior filtration; 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 are on ground level, simplifying maintenance and allowing for quick, easy extraction of fluid samples for analysis.
