On March 4, 2014, the triennial CONEXPO-CON/AGG 2014 opened as scheduled at the Las Vegas Convention Center in the United States.

 

　　At the Hyundai booth, an amphibious excavator, the R220LC-9A, caught customers' attention. “This machine is a new model developed specifically for working in wetlands and swamps. Building on the existing R220LC-9A excavator, we made further breakthroughs by removing the traditional undercarriage and installing hydraulic extension pontoons on the excavator.” Hyundai's regional sales manager for the North American center told reporters, “Each pontoon on this excavator uses 1.62-meter-wide track shoes, so the machine can operate freely even in 1.5 meters of water.”
