- Make the jobsite safer with an optional swing alarm.
Build Number: 07C
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 faster than the previous series.
- Multifunctioning is smoother and more efficient with the hydrostatic swing circuit.
- Enhanced heavy lift mode increases system pressure to help you pick and place heavy material with ease.
- Booms, sticks, and frames are up to two times more durable than the previous series, which will give you years of reliable performance in the harshest environments.
- Match the excavator to the job with three operating modes: Power, Smart, and ECO.
- Advansys™ bucket tips increase penetration and improve cycle times. Tip changes can be done quickly with a simple lug wrench instead of a hammer or special tool, improving safety and uptime.
- Auxiliary hydraulic options give you the versatility to use a wide range of Cat attachments.
- Don’t let the temperature stop you from working. This excavator has a high-ambient capability of 52° C (125° F) and standard cold start capability of –18° C (-0.4° F).
Boost Efficiency and Productivity
- 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 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.
Work In Comfort
- Work year-round with automatic climate control and available heated 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.
- Control the excavator comfortably with easy-to-reach controls all located in front of you.
- Stow your gear with plenty of in-cab storage.
- Use the standard radio’s USB ports and Bluetooth® technology to connect personal devices and make hands-free calls.
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.
- 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 touchscreen monitor.
- 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.
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.
- Track your excavator’s filter life and maintenance intervals via the in-cab monitor.
- Fuel filters are synchronized to be changed at 1,000 hours; they are accessible from the upper platform.
- The advanced air intake filter with pre-cleaner has double the dust holding capacity of the previous air intake filter.
- The new hydraulic oil filter provides improved filtration performance and 3,000 hour replacement interval – 50 percent longer than previous filter design.
- The high-efficiency hydraulic fan has an automatic reverse function to keep cores free from debris, eliminating the need for any operator interaction.
- S∙O∙S ports simplify maintenance and allow for quick, easy extraction of fluid samples for analysis.
Enhanced Safety
- Rearview camera is an available option. Upgrade to 360° visibility and you’ll easily visualize objects and personnel around the excavator in a single view.
- See all around the machine with the premium 360° lighting package and its 1800 lumen lights on the chassis, cab, boom, sides, and rear.
- Serrated steps and anti-skid punch plate on the service platform help prevent slipping.
- A travel direction indicator helps operators know which way to activate the travel levers.
- Enjoy great visibility into the trench, in each swing direction, and behind you with the help of smaller cab pillars, larger windows, and a flat engine hood design.
- A ground-level shutoff switch stops all fuel to the engine when activated and shuts down the machine.
