340 UHD Latest Features

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 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 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

  • 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.

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.
  • 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 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 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.
