Amphibious excavators

The Waterking amphibious excavator is well-suited for various kinds of activities on very poor load-bearing soils, such as wetlands, dredging deposits, ponds, deltas, etc. We rent out three Waterking models (WK 80, WK 220 and WK 250). The machines are inspected yearly and meet the strictest safety and environmental requirements. The amphibious excavators are only rented out with an operator. Our operators all have a basic safety certificate (Basic SCC).

The Waterking is capable of operating in shallow waters up to a depth of 1.5 m. For operating in deeper waters, we can supply additional side-pontoons with spud poles to provide greater floating capacity. The spud poles are 4-6 metres in length and are operated from within the excavator.

Floating capacity: Fully in depths of 1.5 m and over
