Amphibious excavator WK 20

The Waterking WK 20 NG-A is the smallest amphibious excavator of our rental fleet. With this 2-ton class excavator, dredging and mowing activities can be carried out and it is extremely suitable for maintaining narrow waterways. Ideal when waterways are too shallow for a mowing / push boat. But also in circumstances where it is not possible to work from the shore or in poor load-bearing terrains such as wetlands.

The floating excavator is 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.

Specifications WK 20 NG-A

The 20 NG-A can work in shallow waters up to a depth of 1,10 m. When the amphibious excavator starts to float, the use of additional pontoons is mandatory to carry out the work. The additional pontoons are equipped with hydraulic spud poles (operation from the cabin). The machine is adjustable in width from 1,50 m till a max of 2,50 m and can even perform the narrowest position. The floating excavator is easy and relatively inexpensive to transport with our own trailer.

In addition, there are different types of accessories available, such as tilt-, mowing- and riddle bucket.
