340 UHD Ultra High Demolition Hydraulic Excavator

Overview

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 high
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.
340 UHD Tilting Cab
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.
254 mm (10") Color Monitor
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.
340 UHD with Retrofit Boom
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.

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.
Safety
SAFETY
  • 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.
