340 UHD Ultra High Demolition Hydraulic Excavator

The Cat® 340 UHD provides optimum machine solutions for building demolition up to 8 stories. With its unique coupling system, you can switch between two lengths of Ultra High Demolition fronts and two types of Retrofit booms and sticks with no special tools in 15 minutes. You simply won’t find a better 50-ton class choice for demolition..



340 UHD working 7 to 8 stories highTest

PERFORMANCE

  • UHD front parts work (1/2)at 18.6m (60'ft 11in)of vertical pin height, working with a 3.7 ton (8,157 lbs) tool with 11.7m (38ft 4in) 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) and retracted to
    3000 mm (10 ft). Transportation of the machine is simple.
  • Standard rearview and right-hand sideview cameras give clear views on the monitor.
  • The C9.3Bengine 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 new high-efficiency hydraulic reversing fan cools the engine on demand to help reduce fuel consumption.
  • Cat technologies increase operating efficiency to lower operator fatigue and your operating costs, including fuel consumption and daily maintenance.

SIMPLE OPERATION

SIMPLE OPERATIONSIMPLE 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.
  • 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.
  • 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.

EFFICIENCY AND PRODUCTIVITY WITH INTEGRATED 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 Flash works around your schedule to ensure your machine’s software is up to date for optimal performance.
  • The Cat App helps you manage fleet location, hours, and maintenance schedules; it also alerts you for required maintenance and even allows you to request service from your local Cat dealer.
  • The Cat attachment locator can help you find tools, track work time, and plan maintenance and replacement – all through your Cat App- equipped smartphone.
 

340 UHD Hydraulic Service CenterTest

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 precleaner has double the dust holding capacity of the previous air intake filter.
  • The hydraulic oil filter provides improved filtration performance, anti-drain valves to keep oil clean when the filter is replaced, and long life with a 3,000-hour replacement interval – 50% longer than previous filter designs.
  • S•O•SSM ports simplify maintenance and allow for quick, easy extraction of fluid samples for analysis.

SAFETY

SAFETYSAFETY   
  • The standard Stability Monitoring System provides operator- friendly interface with adjustable warning.
  • A travel direction indicator helps operators know which way to activate the travel levers.
  • Enjoy greater visibility in each swing direction with the help of smaller cab pillars and larger windows.
  • A ground-level shutoff switch stops all fuel to the engine when activated and shuts down the machine.
  • Rear and right-hand side cameras are standard.
  • Serrated steps and an anti-skid punch plate on the service platform help prevent slipping.
