EX5600-6 excavator has increased production capacity without a significant increase in its footprint, according to Hitachi. BE-backhoe version has a 44.5-cubic-yard bucket, up from 38 cubic yards; and the BH backhoe front version has a 38-yard bucket, up from 35.5 cubic yards. Hydraulic pump output is 10 percent higher than the predecessor through a gear ratio change in the pump drive gear.
