Product Description
Built for serious earthmoving, the 2020 Komatsu PC450-7 delivers 45-ton class performance at a fraction of new equipment cost. Powered by the Komatsu SAA6D125E-3 six-cylinder turbocharged engine producing 259 kW, this machine combines proven reliability with the kind of digging force — 278 kN bucket, 233 kN arm — that handles demanding cut-and-fill, quarry, and mass excavation work without breaking stride.
Sourced directly from Guangdong, China, this unit represents a smart capital allocation for contractors who need heavy iron without heavy depreciation on a brand-new machine.
