Our model RS80-A series amphibious excavators are suitable for 5-9 ton excavation, many of which are adopted for canal cleaning, waterway widening and wetland maintenance. Meanwhile they are often equipped with hydraulic attachments like pile hammer and clamps to meet wider application requirements. Additionaly, we could also increase two additional RC80-A pontoons on both sides to enable the amphibious excavator to travel through deep water area more safely.
