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 an optional heavy counterweight, allowing larger work tools to handle substantial payloads and achieve exceptional production output.

Save Time and Resources
Extended service intervals and top 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.

  • Standkachel

Bijzonderheden

Go the Distance
The Cat® 340 LRE helps you hit your targets all day long. With standard Cat® Payload and 2D Grade, you can reach up to distances nearly 60 feet (18.28 meters) away. Add in an ergonomic cab, long maintenance intervals that lower your maintenance costs, and a power system that improves fuel efficiency, and you won't find a better excavator for cleaning ditches, canals, and waterways or doing heavier-duty work like dredging and long-distance excavation.

Benefits
Nearly 35% More Reach
Cat Long Reach Excavation Excavators reach nearly 35% farther than those with the standard reach configuration, with approximately 66% of the digging force.

Designed to Dig
Reinforcements in the front linkage and frame allow digging power at a distance without sacrificing durability. A heavier counterweight than equivalent standard reach excavators provides greater stability. Get added versatility with optional tool control for select hydro-mechanical tools

Stable Foundation
The heavy-duty, high, wide undercarriage provides a stable, rugged platform for long-reach digging and loading applications with high ground clearance.

Next Gen Features
Take advantage of Cat Next Generation Excavator features including improved operator comfort, reduced maintenance costs, and better fuel economy. Long reach excavation excavators are compatible with Next Generation Excavator technologies.
