Hyundai's amphibious excavator treads lightly
Hyundai has created its first amphibious excavator, designed for operators looking for an excavating solution when working in wetlands, swamps and marshes,
Using the R220LC-9A 22tonne excavator as the starting point, the firm removed its traditional undercarriage and fitted the excavator with hydraulically extending pontoons.
“Each pontoon uses 1.62m wide track shoes allowing the machine to tread lightly in water up to a depth of 1.5m,” explained Todd Johnson, Hyundai Construction Equipment Americas’ north central district sales manager. “Optional supplementary pontoons can be added to boost machine stability in deeper water - typically up to 4.3M deep.”
Each pontoon uses multi-synchronous hydraulic motors – having more than one motor is said to be required for effective propulsion in virtually any terrain, he said.
