WK 20 NG-A

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.

Specifications WK 20 NG-A

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 or where working from the shore is not possible.

The 20 NG-A  can work in shallow waters up to a depth of 1.1 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 from 1.5 m to 2.5 m width and can also perform work in the narrowest position.

The WK 20 NG-A 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.
