The 181,880-pound R800LC-7A is Hyundai's largest excavator; the next largest model weighs 107,580 pounds. The new model is powered by a Tier 3 Cummins QSX engine, generating 460 net horsepower at 1,600 rpm. Hydraulics have been optimized to improve response time, and the system performs faster and saves fuel. Equipped with a mass-excavator 23-foot-7-inch boom and 9-foot-8-inch arm, the R800LC-7A can handle a 5.93-cubic-yard bucket. Unlike many competitors, Hyundai says it includes many features as standard rather than options. Estimated list price: $997,370.
