In circumstances where it is not possible to work from the shore or in poor load-bearing terrainssuch as wetlands. Or if the water is too shallow for a dredger or silt push boat,one of our amphibious excavators is the solution. The machines are very efficient, crane mats (crawler excavator) are no longer needed. There is no chance of getting stuck in the mud. The machine is fully floating. This makes crossing waterways easy. Thanks to its powerful travel motors, the amphibious excavator is able to drive in and out of the water independently. The relatively low ground pressure ensures a minimum of terrain damage.
