Key Features
When we set out to design our new hydraulic excavators, we kept our eyes on the big picture. Of course, we wanted machines with greater digging capacity. But they also had to be fuel-efficient and economical, while imposing less of a burden on the local and global environments. Applying our advanced technologies, we developed KOBELCO’s new ACERA GEOSPEC series, an entirely new kind of excavator that beautifully balances all the demands of today’s construction industry. Lean and efficient with the capacity to spare, these sleek powerhouses bring a whole new style to the worksite while setting new standards for environmental responsibility.
