The Zero Compromise
High-End Infra Excavator


Infra Excavator

In line with Kobelco’s concept of robust construction machinery that will work long and hard on any site on the planet, the rugged machine body is newly designed, and comprehensive reinforcement makes the attachment more robust. It all adds up to Kobelco’s toughest ever mining excavator. The latest hydraulics technology delivers both high-powered output and lower fuel consumption. As the 10th generation model of Kobelco’s SK series, the SK220 meets the needs of civil engineering.
