Product Description
Engineered with precision by Kato's joint-venture manufacturing in Japan, this 2016 HD820V delivers 20-ton performance through proven Mitsubishi 4M50-TLE3A power. Rated at 112.5 kW and 2000 rpm, the water-cooled 4.9L engine drives dual variable axial piston pumps producing 235 l/min each, feeding a 34.3 MPa working hydraulic circuit for consistent power under load.
Digging force reaches 159 kN (bucket) and 115 kN (arm) in Extra mode, supported by a 5630mm boom and 2930mm stick configuration. Maximum reach extends to 9910mm with 6700mm digging depth, while the 0.45-1.1 m³ bucket range adapts to varied material handling requirements. Operating weight of 19,900 kg distributes across 600mm track plates, maintaining 45 kPa ground pressure for stable operation on compromised terrain.
