Sites where excavators work are typically rugged and challenging. That’s why it’s important that the 374 cab help protect the operator as much as possible from fatigue, stresses, sounds, and temperatures of the job.
Comfort and efficiency of movement help keep operators productive and alert all shift long. The standard seat is wide and adjustable for operators of virtually any size.
The tip-up left console makes getting in and out of the seat easy.
Two cab options – Deluxe, and Premium – let you choose the level of comfort you need.
The Deluxe cab package includes a heated air suspension seat; the Premium seat is heated and cooled.
The cab is sound-suppressed and sealed.
Advanced viscous mounts reduce cab vibration
Control the excavator comfortably with easy-to-reach controls located in front of you.
The touchscreen monitor makes it easy to access critical information and settings. Shortcut keys make it easy, and two are for entertainment, heating, and air conditioning. There is also a shortcut key for apps and functions that you can set.
Standard automatic climate control keeps you at the right temperature throughout your shift.
Convenience features include Bluetooth® integrated radio, USB charging and phone connectivity ports, 12V DC outlets, and an AUX port.
Cup and bottle holders are easy to reach, and storage spaces are located conveniently throughout the cab.

Not all features are available in all regions. Please check with your local Cat® dealer for specific offering availability in your area.

Optional Cat® Command remote control enables equipment operators to work safely outside the machine when working in hazardous environments. Command offers the choice of handheld Consoles* (line-of-sight) or long-distance virtual Stations (non-line-of-sight). Deep integration with machine systems enables efficiency and productivity by maintaining the use of in-cab technology** features (Grade, Payload, Assist, etc.).
Keep your excavator secure with Operator ID. Use your PIN code on the monitor to enable the pushbutton starting feature.
Enhance operator safety by adding Cat® Command to your fleet. The remote-control system keeps you away from potential hazards. The non-line-of-site kit has a Wi-Fi radio, cameras, and a microphone to work anywhere.
Standard 2D E-Fence is integrated right out of the factory, preventing the excavator from moving outside operator-defined set points; the system works with thumb and bucket combinations, hammer, grapple, and clamshell attachments.
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.
The right-hand service platform design provides easy, safe, and quick access to the upper service platform; the service platform steps use serrated steps and an anti-skid punch plate to prevent slipping. The handrails comply with ISO 2867:2011 requirements.
Lift Assist helps you avoid tipping by letting you know if your load is within the excavator’s safe working range limits.
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.
Enhance jobsite safety. Add a swing alarm to alert people when rotating from the trench to the stockpile.
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.
See all around the machine with the premium 360° lighting package and its 1800 lm lights on the chassis, cab, boom, sides, and rear.

The 374 uses a keyless push-button engine start. This adds security for the machine by using Operator ID codes to limit and track machine access. Codes can be entered manually via an optional Bluetooth key fob.
Most machine settings can be controlled through the high-resolution touchscreen monitor. It offers several languages and is easy to reach from the seat – no twisting or turning.
A second 254 mm (10 in) monitor is available for the Cat® Grade and Cat® Grade with 3D.
Operating can be made easier with the touch of a joystick button. The joystick function can be customized through the monitor. The joystick pattern and response can be set to match operator preference. All preferences are saved with the Operator ID and restored at login.
Make moving the excavator much easier with Cat® Stick Steer. Push a button and use one hand to travel and turn instead of both hands or feet on levers or pedals.
You can also add an auxiliary relay to power on or turn off a CB radio, beacon light, or other attachment so you don’t have to take your hands off the joysticks.
Program up to four depth and slope offsets so you can easily get to grade without a grade checker – saving time and enhancing safety on the jobsite.
Operator coaching is an in-cab system that recognizes specific opportunities for operators to be more productive and prevent unnecessary machine wear and tear.
Not sure how a function works or how to maintain the excavator? Always have the operator’s manual at your fingertips on the touchscreen monitor.
Use the in-monitor QR code to learn about machine and technology features through a full suite of “how-to” videos.
