350 Hydraulic Excavator

350

Large Excavators
The Cat® 350 is known for its premier productivity, low owning and operating costs, and easy-to-use Cat technology. With a bucket capacity of up to 3.2 m3 (4.2 yd3) and outstanding digging force and swing torque, the 350 can move tons of material for top production. The cab features large windows at the front, sides, and rear, giving excellent visibility in all directions from the operator's seat. Narrow front cab pillars allow a wider field of view to the front. The 350 will help you get tons of work done on grade and on time.

Availability may vary by region, consult your Cat® Dealer for more details.

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 1,800 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 (2.205 lb.) 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 0.810 kg (1.786 lb.) of refrigerant, which has a CO2 equivalent of 0.001 metric tonnes (0.001 tons).
