340 Long Reach Excavator
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, longer maintenance intervals that lower your maintenance costs by up to 15%, and a power system that improves fuel efficiency by up to 15%, 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.

Note (1)
Net power advertised is the power available at the flywheel when the engine is equipped with fan, air intake system, exhaust system, and alternator with engine speed at 1,900 rpm. Advertised power is tested per the specified standard in effect at the time of manufacture.
Note (2)
¹Cat diesel engines are required to use ULSD (ultra-low sulfur diesel fuel with 15 ppm of sulfur or less) or ULSD blended with the following lower-carbon intensity fuels** up to: 20% biodiesel FAME (fatty acid methyl ester)* or 100% renewable diesel, HVO (hydrotreated vegetable oil) and GTL (gas-to-liquid) fuels.Refer to guidelines for successful application. Please consult your Cat dealer or “Caterpillar Machine Fluids Recommendations” (SEBU6250) for details. *Engines with no aftertreatment devices can use higher blends, up to 100% biodiesel (for use of blends higher than 20% biodiesel, consult your Cat dealer). **Tailpipe greenhouse gas emissions from lower-carbon intensity fuels are essentially the same as traditional fuels.
