Like a number of other excavator builders, Hyundai unveiled new models at the vast bauma 2007 construction and mining machinery trade show held in late April in Munich, Germany. Among the new machines that Hyundai planned to exhibit is the 179,000-pound Robex R800LC-7A, which represents a major class leap from the company's former top-of-the-line, 50-mt R500LC-7A, and is aimed directly at the quarry/small-mine market sector. Equipped with a 4.5 cubic yard bucket capacity, the R800LC-7A is powered by a Cummins QSX 15 Tier 3-certified diesel rated at 460 horsepower. Fully integrated engine control unit (ECU) reportedly offers 10 times the storage and computing power of previous models, for more efficient and intelligent engine management.
