wetland dredging equipment

Tired of dredging river silt and removing aquatic weeds?

Are you troubled by the high costs of renting dredging barges? Vessel-based dredging not only brings expensive labor costs and unsatisfactory cleaning results, but also cannot operate across both land and water.Shandong Yahui Machinery Manufacturing Co., Ltd. has developed amphibious crawler excavators and amphibious crawler transporters to solve these challenges. Equipped with a turbocharged 4108 diesel engine, the machines deliver powerful performance. They can be fitted with specialized underwater reed harvesters, hydraulic slurry pumps and multiple other attachments to realize multi-functional operations. Our equipment efficiently handles complex tasks inaccessible to ordinary barges, including river silt removal and reed & aquatic weed clearing.

Advantages & Features of Amphibious Crawler Excavator

Amphibious pontoon tracked chassis, anti-sinking performance

The widened pontoon track undercarriage generates buoyancy for water travel. It freely navigates swamps, silt lands, shallow beaches and shallow river zones that regular excavators cannot reach. Stable operation is available in water depths ranging from 0.6m to 12m. External buoyancy tanks and positioning assemblies can be installed as an option.

Quick-coupler system for fast attachment switching

The main machine can rapidly switch between reed harvester heads, suction dredging heads, hydraulic breakers, digging buckets and log grapples. A single machine completes reed harvesting, aquatic weed removal, dredging, river excavation and tidal flat renovation, greatly cutting equipment investment costs for overseas customers.

Dedicated working platform for efficient on-water reed harvesting

The front-mounted hydraulic reed cutter continuously cuts and lays down reeds. It supports large-scale harvesting of aquatic reeds, cattails and water weeds, replacing manual labor and resolving the high labor cost pain point for wetland projects worldwide.

Outstanding mobility on extreme complex terrain

Wide steel pontoon tracks achieve ultra-low ground pressure. The machine travels steadily on muddy tidal flats, lake shorelines, mangrove peripheries and swamp depressions. It works all year round without being affected by seasonal flooded wetlands. Rubber track pads are installed optionally, enabling travel on cement roads without surface damage.

Modular design for convenient cross-border ocean shipping

Modular disassembly allows containerized transportation to lower international freight expenses. Powered by globally popular diesel engines, spare parts are widely available overseas for easy maintenance. Optional external buoyancy tanks and thrusters can be added to freely switch between multiple working modes including land travel, amphibious navigation and floating operation.

Eco-friendly operation with minimal ground disturbance

The pontoon tracks cause limited damage to topsoil and avoid deep compaction of wetland sediment. The equipment complies with wetland environmental protection regulations in many countries, ideal for wetland restoration projects with strict environmental standards across Europe, Southeast Asia and other regions.

Application Scenarios of Amphibious Crawler Transporters

Southeast Asia

Reed & aquatic weed removal in the Mekong Delta (Vietnam, Thailand, Cambodia)

Overgrown reeds along Mekong River banks block irrigation channels and hinder inland water transport. Our amphibious equipment travels in shallow water to clear aquatic weeds and guarantee agricultural irrigation and river navigation.

Mangrove wetland maintenance in tropical regions (Malaysia, Indonesia)

Clear invasive aquatic weeds and dead reeds on mangrove tidal flats to protect mangrove ecological corridors. Conventional land machinery cannot access silt-covered tidal zones.

Renovation of tropical aquaculture ponds (Thailand, Vietnam)

Remove reeds and aquatic weeds around shrimp and fish ponds, clear pond sediment and reconstruct aquaculture dykes.

Africa Application of Amphibious Excavators

Resource-oriented reed harvesting in Nile wetland zones (Sudan, Egypt)

Harvest large volumes of reeds for livestock feed and papermaking raw materials. The amphibious machine enters Nile floodplain swamps for large-scale reed collection.

Dredging of seasonal swamp watercourses in West Africa (Nigeria, Ghana)

Seasonal floods submerge inland swamps, where overgrown weeds and reeds block natural waterways and trigger floods. Our equipment clears obstacles in flood-affected wetlands all year round.

Vegetation removal for mosquito breeding control

Clear rampant aquatic weeds and reeds in swamps to reduce mosquito breeding grounds and support public health management.

Working Conditions in Europe, Australia & North America

Wetland ecological restoration along the Great Lakes (USA, Canada)

Invasive aquatic plants such as reeds and cattails occupy living space for native species. Environmental authorities deploy amphibious machinery to control alien vegetation via targeted harvesting.

Wetland management along tributaries of the Rhine and Danube (Germany, France, Netherlands)

Low-disturbance operation meets EU wetland environmental legislation for reed trimming and ecological balance maintenance in river wetlands.

Seasonal floodplain weed control along the Murray River, Australia

Seasonal rains form extensive inland swamps. Spreading aquatic vegetation clogs water conveyance channels, and our equipment ensures stable water supply for inland agriculture.

Applications of Amphibious Crawler Transporters in Central & South America

Aquatic vegetation management in Amazon tributary swamps (Brazil, Peru)

Clear overgrown weeds in shallow swamps to protect native aquatic ecosystems and dredge small navigable tributaries.

Coastal tidal wetland maintenance (Panama, Costa Rica)

Remove reeds on coastal tidal flats to prevent tidal creek blockage and safeguard coastal wetland resources.

Apart from the above regions, amphibious excavators manufactured by Shandong Yahui Machinery Manufacturing Co., Ltd. are widely applicable to numerous working scenarios: resource-oriented wetland reed harvesting (raw materials for reed boards, livestock feed and biomass fuel), landscape vegetation trimming in inland lakes and artificial wetland parks, river dredging, aquatic weed clearance in flood channels and irrigation canals for flood prevention and smooth water conservancy operation, post-disaster swamp cleanup, salvage of lodged reeds and floating debris after floods.Our equipment drastically cuts labor input and improves working efficiency. Unmanned operation is also available as an optional function.
