The Cat® 340 UHD provides optimum machine solutions for building demolition up to 8 stories. With its unique coupling system, you can switch between two lengths of Ultra High Demolition fronts and two types of Retrofit booms and sticks with no special tools in 15 minutes. You simply won’t find a better 50-ton class choice for demolition..
Hydraulic quick disconnect requires no tools to swap booms in 15 minutes; choose your front - work up to 22 m with a 3.7 T tool (72 ft with 8,160 lb tool) or up to 25 m with a 3.3 T tool (82 ft with 7,275 lb tool) front or basement to 2 story work and truckloading with Retrofit.
Variable gauge undercarriage provides excellent stability extended and ease of transportation retracted.
Deluxe cab tilts 30 degrees for a more ergonomic operator station includes P5A high resistance glass for safety and premium seat for comfort while 254 mm (10 in) color touchscreen indicates easy to read stability monitoring system information.

| 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 equivale 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). |
