Overview

Quality, Reliability and Durability Come Standard.

The Cat® 340 is evidence of our time-proven engineering and manufacturing know-how for top-notch quality, reliability, and durability. In addition to a powerful engine with millions of hours of service and reinforced booms and sticks for taking on hard and heavy work, the standard, heavy-duty reinforced undercarriage expertly absorbs the stress between jobsite terrain and machine. Built for rugged conditions, this rock-solid machine will help you turn payloads into profit.

Benefits

Get More Work Done

The 340 features high horsepower, a wide undercarriage, and a heavy counterweight, allowing larger work tools to handle substantial payloads and achieve exceptional production output.

Save Time and Resources

Extended service intervals and industry-leading fuel efficiency mean you’ll spend more time working and less time and money on maintenance.

Easy-to-Use Technology

Available technology enables operators of all skill levels to produce faster, better cuts and fills and more accurate payloads. Cat Grade and Payload enhance speed, accuracy, and operating efficiency. Cat E-Fence improves jobsite safety for you, your team, and others.
