Product Description
Built around Komatsu's SAA6D125E-5 engine — a 11.04L, 6-cylinder, water-cooled, turbocharged direct-injection powerplant rated at 257 kW / 1,900 rpm — the PC450-8 represents precision Japanese engineering at the 45-ton class. Electronic speed regulation and a dual axial-plunger hydraulic system delivering up to 690 L/min of main pump flow give this machine the muscle and control demanded by large-scale civil, mining, and infrastructure operations.
