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

| 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 2,000 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) and are compatible* with ULSD blended with the following lower-carbon intensity fuels** up to: 20% biodiesel FAME (fatty acid methyl ester)*** 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. *While Caterpillar engines are compatible with these alternative fuels, some regions may not allow their use. ** Tailpipe greenhouse gas emissions from lower-carbon intensity fuels are essentially the same as traditional fuels. *** Engines with no aftertreatment devices are compatible with higher blends, up to 100% biodiesel (for use of blends higher than 20% biodiesel, consult your Cat dealer). |

| Air Conditioning | The air conditioning system on this machine contains the fluorinated greenhouse gas refrigerant R134a or R1234yf. See the label or instruction manual for identification of the gas. If equipped with R134a (Global Warming Potential = 1430), the system contains 1.000 kg (2.205lb.) of refrigerant, which has a CO2 equivalent of 1.430 metric tonnes (1.576 tons). If equipped with R1234yf (Global Warming Potential = 0.501), the system contains 0.790 kg (1.742 lb.) of refrigerant, which has a CO2 equivalent of 0.001 metric tonnes (0.001 tons). |
