Amphibious Equipments’ working conditions are mainly wetlands and soft terrains. Wetlands are areas where water covers the soil, or is present either at or near the surface of the soil all year or for varying periods of time during the year, including during the growing season. They can be saltwater, freshwater, or brackish. The most common categories of wetland are marsh, swamp, and peat bog. Soft-terrain is any ground condition that will not support traditional heavy equipment, even a person can't stand in that ground.

Wetlands and soft terrain is inaccessible to the conventional equipment designed to work either in deep water in the case of boats, or barges, or on firm ground as excavators, cranes or drill rigs etc, because water is too shallow or obstructed for water-based machines, and too soft for conventional heavy equipment. This unique challenge requires a different machine that both demonstrating the low ground pressure and performing heavy work in soft ground, wetlands, marsh and swamp. That is just what amphibious equipment or marsh equipment could do. They are specially designed and the pontoon undercarriage creates buoyancy, giving the machine capabilities between those of a barge and a regular excavator.
