Amphibious excavator

An amphibious excavator (or pontoon excavator or floating excavator) is a type of excavator that can perform dredging while afloat on soft terrain such as swamp, wet land, and shallow water. An amphibious excavator is better adapted for removing silty clay, clearing silted trenches, swampland operation, and shallow water operation than traditional barge-mounted dredgers.[1]

Walking and working

The amphibious excavator can walk or work in water, because the chassis crawler floats on sealed pontoons. It may swing or even roll over when excavating with no support underneath. It moves using a dual-body boat form buoyancy tank. A reducer drives the crawler chain, allowing free and smooth movement. Its upper structure is a modified excavator that allows 360° full rotation and hydraulic operation.

Sealed pontoon

The pontoons are manufactured from high tension steel and they are atmospheric corrosion- and saltwater-resistant. Each pontoon has 5 independent water tight compartment with maintenance hole. The bottoms of the pontoons are reinforced for rough terrain operation. The power for the pontoon tracks is provided by an excavator engine and main hydraulic pumps with traveling motors.

Amphibious Excavator Market Overview

For the forecast period 2020-2026, the amphibious excavators market is predicted to have a modest growth rate of 5%. Specifically designed to work in shallow water, these excavators are available for rent at a reasonable cost. Increased maritime traffic, as well as new seaport development and expansion of existing ports, are all contributing to the market's expansion. These factors are creating a significant demand for dredging services. Governments conduct dredging efforts in shallow water reservoirs on a regular basis in order to keep the water reservoirs clean and the flow of rivers unimpeded. It is because of this that the dredging business generates large money from government contracts and that the market for dredging equipment has increased demand.[2]
