Cat 340 Hydraulic Excavator

340 Hydraulic Excavator

Overview

With up to 10 percent more productivity than the model it replaces, the Cat® 340 is the best in its class for moving tons per hour. Add in the excavator’s low owning and operating costs and you will profit like nobody’s business.

High Performance
  • The C9.3B engine generates more power than the 2020 model year 336 engine.
  • More power to the pumps, wider undercarriage, and heavy counterweight enable up to 10 percent more productivity.
  • Match the excavator to the job with three power modes – Power, Smart, and Eco. Power mode is maximum power all the time. Smart mode automatically matches engine and hydraulic power to digging conditions, providing maximum power when needed and reducing power when it isn’t to help save fuel. Eco mode reduces engine speed and keeps it constant to reduce fuel consumption.
Boost Efficiency and Productivity
  • Boost productivity up to 45 percent with optional Cat Grade technology.
  • 2D Grade indicates depth and slope on the monitor with auditory alerts.
  • Grade Assist helps you stay on grade – simply and effortlessly – with single-lever digging.
  • Automatically stop excavator swing at operator-defined set points in truck loading and trenching applications with optional Swing Assist, which will help you use less effort and consume less fuel.
Built for Rugged Conditions
  • Reinforced structures ensure long-term durability in harsh environments.
  • Work up to 4500 m (14,764 ft) above sea level.
  • Standard high-ambient temperature capability is 52° C (125° F) with cold start capability at –18° C (0° F).
  • An optional battery operated engine heater enables starting at –32° C (–25.6° F).
Work in Comfort
  • Choose between Deluxe and Premium cabs – both with automatic climate control.
  • Deluxe cab comes with heated seat to keep you warm.
  • Premium cab comes with heated and ventilated seat for year-round comfort.
  • Control the excavator comfortably with easy-to-reach controls all located in front of you.
Simple to Operate
  • Start the engine with the push of a button; use a Bluetooth key fob or Operator ID passcode.
  • 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.
  • Trouble cutting through tough material? Auto dig boost gives you an automatic power increase of 8 percent when you need it for better bucket penetration, shorter cycle times, and greater payloads.
Easy Maintenance
  • Expect less maintenance cost due to 1,000 hour engine oil intervals.
  • Change all fuel filters at a synchronized 1,000 hours. Filters are grouped and located on right-hand side of machine for easy maintenance.
  • Check hydraulic system oil and easily drain fuel system water and fuel tank water from ground level.
Enhanced Safety
