Overview

If you want high production and more durability with less maintenance, the 374 is a terrific choice. With 10 percent more swing torque than the 374F it replaces, you’ll experience faster cycle times. Plus you get two times more structural durability and up to 20 percent less maintenance for longer service life and greater uptime.

High Performance
  • The 374 can load up to 33 trucks per hour with 36 tonne (40 ton) capacity.
  • Swing torque increase of 10 percent makes cycle times much faster than the previous series.
  • Multifunctioning is smoother and more efficient with the new hydrostatic swing circuit.
  • Enhanced heavy lift mode increases system pressure to help you pick and place heavy material with ease.
Boost Efficiency and Productivity with Cat Technology
  • Standard Cat PAYLOAD on-board weighing system: Achieve precise load targets and increase loading efficiency with on-the-go weighing and real-time estimates of your payload without swinging.
  • VisionLink® helps you remotely manage production targets. The monitor’s USB port lets you download your results from one shift all the way up to 30 days of work so you can manage progress without needing an internet connection or VisionLink subscription.
Simple to Operate
  • 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.
  • Program up to four depth and slope offsets so you can easily get to grade without a grade checker – a real time saver and safety enhancer on the jobsite.
Work In Comfort in the All-New Cab
  • Choose between Deluxe and Premium cabs – both with automatic climate control.
  • Stay warm with the Deluxe heated seat; stay warm and cool with the Premium heated and ventilated seat.
  • Get in and out of the cab easier using the tip-up left console.
  • Advanced viscous mounts reduce cab vibration up to 50 percent over previous excavator models.
Less Maintenance
  • Expect up to 20 percent less maintenance cost than the 374F due to reduced hydraulic oil capacity and extended and synchronized service intervals
  • The excavator is auto lube ready with built-in mounting points; an available auto lube retrofit kit provides additional hardware to mount a grease pump and line guards.
Enhanced Safety
  • Standard 2D E-Fence is integrated right out of the factory, which prevents the excavator from moving outside of operator-defined set points.
  • Lift Assist helps you avoid tipping by letting you know if your load is within the excavator’s safe working range limits.
  • Rear and right-hand-sideview cameras are standard. Upgrade to 360° visibility and you’ll easily visualize objects and personnel around the excavator in a single view.

  • Boost productivity versus traditional grading with standard Cat GRADE with 2D system – includes indicate-only and laser capability.
  • Upgrade easily to optional Cat GRADE with Advanced 2D or 3D.
  • 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.
  • 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.
  • 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.
  • 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.
Simple to Operate
  • 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.
  • Program up to four depth and slope offsets so you can easily get to grade without a grade checker – a real time saver and safety enhancer on the jobsite.
  • 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.
  • Automatic hydraulic oil warm up gets you to work faster in cold temperatures and helps prolong the life of components.
  • Navigate quickly on the standard high-resolution 254 mm (10 in) touchscreen monitor or with the aid of the jog dial control.
  • A second 254 mm (10 in) monitor is available for the Cat GRADE with Advanced 2D and Cat GRADE with 3D.
  • The Cat PL161 Attachment Locator is a Bluetooth device that makes finding your attachments and other gear quick and easy. The excavator’s onboard Bluetooth reader or Cat App on your phone will locate the device automatically.
  • Save more time and energy with available work tool recognition. A simple shake of the attached tool confirms its identity; it also ensures all the attachment settings are correct so you can get to work quickly and efficiently.
  • 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.
  • Need more lift during your shift? Turn on Auto Heavy Lift and get 8% more power exactly when you need it for as long as you need it.
