Product Description
Engineered in Japan and built to perform under sustained operational demand, the Kato HD1023 represents a benchmark in the 23-ton crawler excavator class. At its core sits a Mitsubishi 6D16-TE1 six-cylinder, water-cooled diesel engine displacing 7.545 liters and delivering 125 kW at 2,200 rpm — a proven powertrain known for durability across heavy-cycle applications.
Hydraulic performance is driven by a dual variable axial piston pump system with a maximum combined flow of 249 × 2 L/min, operating at a working circuit pressure of 29.4 MPa. Bucket digging force reaches 174.6 kN in Extra mode, while arm digging force hits 125.5 kN — figures that translate directly to productivity on hard material and deep excavation cycles.
