Cat 350 Hydraulic Excavator - RELIABLE IN ALL WEATHER

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 auditor alerts.
  • Grade Assist helps you stay on grade – simply and effortlessly – with single-lever digging.
  • Automatically stop excavator swing at operator-defined setpoints in truck loading and trenching applications with Swing Assist, which will help you use less effort and consume less fuel.
  • Cat Payload onboard weighing helps you achieve precise load targets to improve your operating efficiency. Pick up a load of material – with either a bucket or grapple – and get a real-time weight estimate without even swinging.
  • Combine Payload with VisionLink® and remotely manage your production targets. The monitor's USB port lets you download results from one shift all the way up to 30 days of work so you can manage your progress without needing an internet connection or VisionLink subscription.
  • Upgrade to Cat Grade with Advanced 2D and create and edit grade designs with ease on a second high-resolution 254 mm (10 in) touchscreen monitor.
  • Upgrade to Cat Grade with 3D and create and edit designs with ease and see the front linkage's full range of motion on a second high-resolution 254 mm (10 in) 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.
  • All Cat Grade systems are compatible with radios and base stations from Trimble, Topcon, and Leica.
  • Already invested in a grade infrastructure? You can install grade systems from Trimble, Topcon, and Leica onto the machine.
  • Remote troubleshoot connects you to a dealer service pro 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.
  • 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.

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.
  • Tilt-up console enables easy entry and exit.
  • 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 to personal devices and make hands-free calls.

Built For Rugged Conditions

  • The reinforced swing bearing, along with stress-relieved boom and stick, enables the 350 to take on tough work over and over again.
  • Work up to 4500 m (14,764 ft) above sea level.
  • Standard high-ambient temperature capability is 52°C (125°F). Standard cold start capability is -18°C (0°F); -32°C (-25°F) cold start capability is an available option.
  • Automatic hydraulic oil warmup gets you to work faster in cold temperatures and helps prolong the life of components.
  • Three levels of filtration protect the engine from dirty diesel fuel.
  • Grease sealed between track pins and bushings reduces travel noise and prevents debris from entering to increase undercarriage life.
  • Standard built-in protection includes bottom, travel motor,and swivel guards.
  • The sloped track frame prevents mud and debris accumulation, helping reduce risk of track damage.

High Performance, Low Fuel Consumption

  • Powerful digging force and strong swing torque enable the use of large buckets up to 3.2 m3 (4.2 yd3) for class-leading productivity.
  • Compared to the Cat 349-07, the 350 consumes up to 13 percent less fuel for lower operating costs and greater profit potential.
  • Match the excavator to the job with three power modes – Smart, Power, and Eco. 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. Power mode is maximum power all the time. Eco mode reduces engine speed and keeps it constant to reduce fuel consumption.
  • Valve priority puts hydraulic pressure and flow where you command it to go for fast light- to medium-load cycle times.

Cat 350 Hydraulic Excavator - HIGH PERFORMANCE, LOW FUEL CONSUMPTION
Cat 350 Hydraulic Excavator - SIMPLE TO OPERATE

Simple To Operate

  • Start the engine with a push 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 cuting 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.
  • Need more lift during your shift? Auto heavy lift gives you 8 percent more power exactly when you need it for as long as you need it.
  • Make moving the excavator much easier with optional Cat Stick Steer. Simply push a button and use one hand to travel and turn instead of both hands or feet on levers and pedals.
  • Navigate quickly on the standard high-resolution touchscreen monitor or with the aid of the jog dial control.
  • Protect your hammer from overworking. Auto hammer stop warns you after 15 seconds of continuous firing and then automatically shuts it off after 30 seconds – all to prevent wear and tear on the attachment and excavator.
  • 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.

Enhanced Safety

  • Keep your excavator secure with Operator ID. Use your PIN code on the monitor to enable the push button starting feature.
  • A travel direction indicator helps operators know which way to activate the travel levers.
  • A ground-level shutoff switch stops all fuel to the engine when activated and shuts down the machine.
  • Enjoy great visibility into the trench, in each swing direction, and behind you with the help of smaller cab posts and larger windows.
  • Serrated steps and anti-skid punch plate on the service platform help prevent slipping.
  • A rearview camera is standard.

Cat 350 Hydraulic Excavator - ENHANCED SAFETY

Easy Maintenance

  • Expect less maintenance cost due to extended and synchronized service intervals.
  • Check hydraulic system oil and easily drain fuel system water from ground level.
  • Track your excavator's filter life and maintenance intervals via the in-cab monitor.
  • Oil and fuel filters are grouped and located on right-hand side of machine for easy maintenance.
  • The air intake filter with pre-cleaner has high dust holding capacity.
  • Keep your excavator secure with Operator ID. Use your PIN code on the monitor to enable the push button starting feature.
  • The hydraulic oil filter provides improved filtration performance, anti-drain valves to keep oil clean when the filter is replaced, and longer life with a 3,000 hour replacement interval – 50 percent longer than previous filter designs.
  • S·O·SSM ports are on ground level, simplifying maintenance and allowing for quick, easy extraction of fluid samples for analysis.
