Caterpillar introduced three new C-Series wheeled excavators, the M316C, M318C and M322C. The M316C, a new size in the lineup, delivers 138 net horsepower and has an operating weight of 35,800 to 40,200 pounds.
A new Cat 3056E ATAAC engine provides power for all three models. This electronically controlled engine is turbocharged and air-to-air aftercooled to boost performance, reduce emissions and extend piston and cylinder bore life. The engine is integrated with a variable-speed, on-demand cooling fan, which reduces average fan speed, minimizing fuel consumption and noise.
