**Tailpipe greenhouse gas emissions from lower-carbon intensity fuels are essentially the same as traditional fuels.
340 Variable Angle Boom Configuration
The Cat® 340 Variable Angle Boom 6.6m (21'8") (VAB) provides one extra articulation to maximize your application range while minimizing the space required to rotate in tight earthmoving and demolition sites, allowing you to work closer to the machine.
On-Board Cat Technology Helps Increase Efficiency
- This configuration is equipped with standard Cat technologies, including Standard Grade Assist, Cat Payload, and 2D E-Fence, which boosts operating efficiency through technology and is compatible with VisionLink®, Cat PL161 attachment locator, Remote Troubleshoot, Remote Flash, and Cat Inspect, allowing you to eliminate the guesswork in managing your equipment.
- Cat Grade Assist for excavators automates boom and stick movements for more accurate cuts with less effort. It uses machine position sensors and operator-defined depth and slope parameters to enable single-lever digging, helping improve efficiency.
- Cat Payload helps you achieve precise load targets to improve your operating efficiency. Pick up a load of material--with a bucket and thumb combination or grapple and clamshell attachments--and get a real-time weight estimate without swinging.
- The 2D E-Fence prevents the excavator from moving outside operator-defined set points. The system works with thumb and bucket combinations, hammer, grapple, and clamshell attachments.
Demolition Cab Compatibility
- For demanding demolition sites, the 340 VAB is compatible with the optional demolition cab that tilts up to 30° for a more productive and comfortable sight line.
- The front windshield and roof window are made with EN 356 P5A glazing for enhanced impact resistance and have one-piece parallel wipers with three intermittent settings and washer spray.
- Standard Operator Protective Guards (OPG) help protect the roof and front reinforced EN356 P5A laminated windows from falling debris during demolition while helping to maintain visibility on the jobsite.
- The optional demolition cab features a larger premium heated and cooled seat with a 254 mm (10 in) high-resolution touchscreen monitor. The monitor allows operators to view the active stability monitoring system, which gives audible and visual alerts when the work tool's position approaches its stability limit.
- Get in and out of the cab with ease using the tip-up left console.
- Control the excavator comfortably with easy-to-reach controls located in front of you.
- 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 personal devices and make hands-free calls.
- Rearview and side-view cameras are standard. You can also upgrade to 360° visibility to view objects and personnel around the machine in a single view.
- Grease sealed between track pins and bushings reduces travel noise and prevents debris from entering to increase undercarriage life.
The 340 VAB configuration is available for Europe only.
