Case Construction Equipment's CX800B excavator.

Near-zero tail swing on the new Doosan DX235LCR crawler excavator allows it to work close to buildings and in confined areas without sacrificing performance and stability. With a tail swing radius of 5-feet-6-inches and a tail swing of just 3.75 inches over standard 31.5-inch shoes, the DX235LCR is designed to work on congested jobsites such as roadways and rail lines without blocking traffic in the adjacent lane or track. Powered by a 166 hp 6-cylinder Doosan turbocharged diesel engine, the DX235LCR has an operating weight of 53,572 pounds with standard boom, arm and 1.2 cubic yard bucket. Bucket breakout force is 33,510 pounds while arm breakout force is 23,810 pounds. Use of power boost increases both forces by about 5 percent, the highest of any excavator in this class. Maximum digging reach is 32 feet 3 inches and maximum digging depth is 21 feet 11 inches. Dump height is 26 feet 1 inch. Depending on the application, the operator can choose between three working modes — power, standard or economy.
