KCMA Corp., a subsidiary of Hitachi Construction Machinery Group, rolled out the 957Z wheel loader. Equipped with a six-cylinder, 16-liter Isuzu diesel engine, the loader does not need a diesel particulate filter to meet Tier 4 Final requirements. Improvements in the standard lock-up torque converter speed cycles and improve fuel efficiency. Systems respond more quickly to vehicle demands to improve power and speed, while a new joystick steering option opens up the operator area for increased visibility and comfort. An XT package can also be equipped to handle 12-ton payloads, which allow for two pass loading on 24-ton dump trucks.
