PERFORMANCE
- UHD can reach up to 18.6m (60 ft 11 in) of vertical pin height, working with a 3.7 ton (8,157 lbs) tool with 11.7m (38 ft 4 in) horizontal reach.
- Cat active stability monitoring system continuously informs operators of work tool position within the safe working range and warns when approaching the stability limit.
- Hydraulically actuated variable gauge undercarriage provides outstanding stability extended to 4000 mm (13 ft); it retracts to 3000 mm (10 ft) to make transportation easier.
- Standard rearview and right-hand sideview cameras give clear views on the monitor.
- The C9.3B engine can run on biodiesel up to B20 and meets EU Stage V, U.S. EPA Tier 4 Final, and Japan 2014 emission standards.
- Match the excavator to the job with three power modes – Power, Smart, and ECO. Smart mode automatically matches engine and hydraulic power to working requirements, providing maximum power when needed and reducing power when it isn’t to help save fuel.
- The high-efficiency hydraulic reversing fan cools the engine on demand to help reduce fuel consumption.
- Cat technologies increase operating efficiency to lower operator fatigue, operating costs, and fuel consumption.
OPERATOR COMFORT
- Demolition cab with standard Operator Protective Guards (OPG) includes front and roof of P5A
10 mm (0.4”) laminated glass. - Tilt-up 30° for a more productive and comfortable sight line.
- The windshield and roof one-piece parallel wipers with three intermittent settings includes washer spray.
- Premium heated and cooled seat is standard.
- Get in and out of the cab easier using 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.
- Use the standard radio’s USB ports and Bluetooth® technology to connect personal devices and make hands-free calls.
SIMPLE OPERATION
- 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.
- Automatic hydraulic oil warmup gets you to work faster in cold temperatures and helps prolong the life of components.
- Navigate quickly on the 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.
- 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.
EFFICIENCY AND PRODUCTIVITY WITH CAT TECHNOLOGY
- 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.
MAINTENANCE
- Enjoy low maintenance cost due to extended 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 are grouped and located on the right-hand side of the machine for easy maintenance.
- The engine air intake filter with pre-cleaner has double the dust holding capacity of the previous air intake filter.
- The hydraulic oil filter provides improved filtration; anti-drain valves keep oil clean when the filter is replaced.
- 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•SSM ports simplify maintenance and allow for quick, easy extraction of fluid samples for analysis.
SAFETY
- On-board stability monitoring helps the operator enhance job safety.
- A travel direction indicator helps the operator know which way to activate the travel levers.
- Enjoy greater visibility in each swing direction with the help of narrow cab pillars and large windows.
- 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.
- Serrated steps and an anti-skid punch plate on the service platform help prevent slipping.
- Standard 2D E-Fence (swing) helps you avoid swinging into obstacles to the side of the machine such as live traffic and structures.
SUSTAINABILITY
- 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 (hydrogenated 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.
*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.
