Excavator in Lake 

The amphibious undercarriage is specially designed to maneuver in difficult conditions, such as swamps, inland lakes, rivers and shallow waters, where it is difficult to carry a standard excavator.
Some locations, such as bay habitats, wetlands, remote islands, coastlines, and submerged aquatic vegetation, require specialized machinery.
An amphibious excavator is a type of excavator that features sealed pontoon gear that allows it to perform dredging work while floating in shallow water.
The pontoons are built with high tensile strength steel, due to the working conditions in which they find themselves, they are resistant to corrosion and capable of working in conditions of high salinity as in the case of working with sea water.
This ensures that the excavator can operate even in extreme conditions. It is a piece of equipment that is specifically designed to maneuver in swampy areas such as wetlands and soft ground, as well as to float on water. These excavators are fully self-propelled using a hydraulic direct drive guide system.
The physical principle that makes the amphibious excavator possible lies in hermetically sealed pontoons.
Coupled with its large size, this creates really low ground pressure. The machine is capable of operating in dry, soft and swampy areas with little or no risk of getting caught in the mud.
Undercarriages are considered one of the main innovations in the area of ​​the construction industry.
These excavators are capable of operating in the harsh wetlands that are common throughout the world, especially in North America and Europe.
Engineers were generally limited to operations on dry land, so under these conditions they would have to figure out how to make dry land for these machines by building roads or running barges through canals.
Because these overall wetland-related costs needed to be reduced, engineers developed amphibious landing gear.
Amphibious landing gear could be installed on excavators and other heavy duty equipment, attaching the landing gear gives it buoyancy and the ability to work in wet environments without the need to build a solid foundation to transport it.
