Build Number: 07E


  • UHD can reach up to 28 m (90 ft) of vertical pin height, working with a 3.7 ton (8,157 lbs) tool with 15.8 m (51 ft) 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 when 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 C13 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.


  • Demolition cab with FOGS 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 include 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.
  • UHD front is worktool camera ready for easy dealer-available kit installation and includes water-spray-system-ready wiring and hoses.
  • 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.


  • 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.


  • 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.
  • 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.
  • Remote troubleshoot connects you to a dealer service professional 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.
  • The Cat PL161 attachment locator can help you find tools, track work time, and plan maintenance and replacement.


  • 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 excellent filtration; anti-drain valves keep oil clean when the filter is replaced.
  • S•O•SSM ports simplify maintenance and allow for quick, easy extraction of fluid samples for analysis.


  • On-board stability monitoring helps the operator enhance jobsite 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 narrowr 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.


  • The Cat® C13 engine meets U.S. EPA Tier 4 Final, EU Stage V, and Japan 2014 emission standards.
  • The 352 UHD emits up to 31% less CO2 than the 345C*.
  • 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 reduces unnecessary fuel burn and greenhouse gas emissions by allowing the engine to automatically go into idle mode when the machine is not working.
  • Cat Scheduled Oil Sampling (S•O•S℠) Services helps reveal excessive wear, contaminated fluids or other “unseen” issues that can shorten component life. In many cases, you can extend oil and coolant change intervals by using fluid monitoring. Consult your Cat dealer or the machine's operation and maintenance manual for more information.
  • 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.
  • Remote troubleshoot decreases maintenance time and keeps your machine running with maximum efficiency by allowing your Cat dealer to virtually test the machine while working. Once a problem is identified, a technician can fix it the first time, saving time and money.

*All comparisons to 345C. Productivity, fuel, and CO2 emissions vary by application. CO2 emissions calculations based on a reference work cycle using 2.2 U.S. gallons per hour of #2 U.S. diesel fuel based. Applies IPCC2006 methodology using U.S. EPA Emissions Hub emission factors. Includes DEF (diesel exhaust fluid) related CO2. Fuel measurements are at 15°C. Estimated average fuel consumption improvements are based on tests or Product Link® data where available. Productivity improvements are based on test data.
**Engines with no aftertreatment devices can use higher blends, up to 100% biodiesel.
