Introduction to Amphibious Wetland Excavators (Pontoon Excavators)
Amphibious excavators—also known as swamp or Wetland excavators—are specialized pieces of heavy construction machinery.
Core Structural Features
The upper structure consists of a standard Hydraulic Excavator unit, while the undercarriage is replaced by sealed pontoon floats and widened tracks. The pontoons provide buoyancy, and the tracks allow the machine to traverse silt and shallow water without sinking like a conventional excavator; this enables seamless operation across land, swamps, and shallow water zones.
Key Functions
River Dredging and Desilting
Clearing silt and weeds from riverbeds and ditches, as well as widening and deepening waterways (e.g., excavating silt directly from the river channel); this is the most common application in inland waterway management.
Wetland and Tidal Flat Ecological Restoration
Wetland rehabilitation, swamp excavation, tidal flat development, and reed pond management, helping to preserve wetland water systems.
Hydraulic Embankment Construction
River levee reinforcement, cofferdam excavation, flood control and emergency response, and flood defense operations in low-lying areas.
Pond and Fish Farm Modification
Excavating fish ponds, desilting shrimp ponds, and removing sediment from reservoirs.
Soft-Ground Earthworks
Excavation in swamps and low-lying soft-soil areas; capable of operating on muddy terrain inaccessible to standard excavators.
Advantages
Moves freely through shallow water and silty swamps without the need for support vessels;
Versatile functionality; supports interchangeable attachments such as buckets and Hydraulic Breakers;
Suitable for operations in narrow rivers and wetlands where large dredging vessels cannot enter.
Applicable Scenarios
River management, wetland restoration, hydraulic engineering, tidal flat development, fish pond modification, and flood control/emergency response.
Amphibious wetland excavators utilize a pontoon-track undercarriage to operate in swamps, shallows, and silty river zones. They are primarily used for river dredging, wetland restoration, pond excavation, and embankment construction, making them ideal for soft, water-logged environments where standard excavators cannot operate.
LiuGong 913 Wetland excavator for Soft Ground, Dredging and Drainage
When I talk with customers about Excavators for wetlands, I usually start with one simple question: Where will the machine actually work? That question sounds basic, but it can save a lot of trouble later.
A machine that works perfectly well on a normal construction site may behave very differently when it enters soft soil, marshland, riverbanks, ponds, muddy farmland, or waterlogged ground. The machine may sink, lose traction, become difficult to turn, or spend more time getting unstuck than doing the actual job.
This is where a LiuGong 913 Wetland excavator becomes an interesting option for customers looking for a compact-to-medium excavator platform for soft-ground applications. The LiuGong 913E is an approximately 13.5-ton Excavator platform, with a published rated power of 74 kW and standard bucket capacity of about 0.55 m³ on LiuGong's current product page.
I want to make one point clear from the beginning. “LiuGong 913 Wetland excavator” is the product keyword we use to describe a LiuGong 913-class excavator prepared for wetland work. It should not automatically be understood as the official name of a separate LiuGong factory model. LiuGong's official product information identifies the machine as the 913E.
For customers who need a machine for wetland construction, drainage, dredging, agricultural land improvement, riverbank work, pond excavation, or similar jobs, we can discuss the actual LiuGong model, undercarriage arrangement, attachments, and working configuration according to the site.
At Ganglong Heavy Industry Technology (Hefei) Co., Ltd., together with Hefei Ganglong International Trade Co., Ltd., we work with construction machinery, mining machinery, agricultural machinery, and matching attachments. We can help customers source suitable equipment, arrange inspection and preparation, and handle international shipping requirements.
In simple language, a wetland excavator is an excavator prepared to work where the ground is soft and ordinary construction equipment may struggle.
The basic machine still works in the familiar way. The engine provides power. The hydraulic system sends that power to the boom, arm, bucket, swing system, and travel motors. The operator uses the controls to dig, lift, swing, move, and place material.
The difference is mainly in how the machine is matched to the ground.
When the soil is firm, the excavator can normally sit on its crawler tracks without much trouble. But soft soil behaves differently. It can deform under load. If the machine puts too much pressure on a small contact area, the tracks can sink into the ground.
For wetland work, I therefore look at the crawler system very carefully. Wider track shoes or a suitable extended undercarriage can spread the machine's weight over a larger area. This can help reduce the pressure placed on the ground and improve mobility, although the actual result depends on soil strength, machine weight, water depth, track dimensions, and operating conditions.
LiuGong's published 913E information lists a standard track shoe width of 500 mm. One official 913E brochure also lists 500 mm, 600 mm, and 700 mm shoe-width configurations.
That difference is important for wetland projects. I do not simply look at the name “913” and assume that every machine has the same ground-contact arrangement. I check the actual machine specification and the customer's working environment before discussing the final configuration.

Soft-ground infrastructure work
The key idea is simple: the excavator must be matched to the ground instead of expecting the ground to cooperate with the machine.
If you have operated a normal excavator, the basic working principle will look familiar.
The engine drives the hydraulic system. Hydraulic pumps send oil through the control valves to different hydraulic motors and cylinders. These components move the boom, arm, bucket, swing structure, and crawler tracks.
On the LiuGong 913E, official specifications list a Cummins QSF3.8 engine, a maximum hydraulic system flow of 240 L/min on one regional product page, and a system pressure around 34 MPa.
These numbers are useful when we talk about the standard machine, but wetland work requires another layer of thinking.
Ground pressure is basically about how much load the machine puts onto the soil. Think about standing on wet mud with normal shoes versus standing on the same mud with wide boards under your feet. The wider contact area spreads your weight.
A similar principle applies to crawler excavators.
One LiuGong 913E brochure gives a reference ground pressure of 42.5 kPa with its listed configuration. The same brochure specifies a 500 mm shoe width for that configuration and also lists wider shoe options.
I would not use that 42.5 kPa number as a guaranteed value for every LiuGong 913 Wetland excavator. Once the track width, counterweight, attachment, boom, arm, fuel level, and other configuration details change, the actual machine weight and ground pressure can change as well.
Balance becomes even more important when the machine is working on wet ground.
Imagine digging a heavy bucket of wet soil while the machine is standing on soft ground. The load is not only moving vertically. It also changes the forces acting on the upper structure and undercarriage as the operator swings the machine.
This is why I always consider the bucket, boom, arm, counterweight, crawler arrangement, and working radius as a complete system.
Hydraulic control also matters. Smooth movement is often more useful than simply having a large number on a specification sheet.
The LiuGong 913E uses an electronic control system designed to coordinate the engine and hydraulic system. LiuGong describes its IPC control system as a way to match engine, pump, hydraulic, and electrical systems to the working condition.
For wetland work, smooth control helps the operator make small movements when positioning the bucket, working near water, or moving material from one side of the machine to another.
The LiuGong 913E is listed at approximately 13,500 kg operating weight on LiuGong's current official product page.
This gives the machine a useful position between smaller Compact Excavators and much heavier 20-ton-class machines. For many drainage, agricultural, municipal, and environmental projects, a 13.5-ton-class excavator can offer enough working ability without bringing the size and transport demands of a much larger machine.
Of course, wetland work is not automatically better with a smaller excavator. The right size depends on digging depth, material density, working reach, transport conditions, and ground bearing capacity.
The crawler system is one of the first things I check.
The standard 913E specification published by LiuGong shows a 500 mm track shoe width. The official brochure also lists 600 mm and 700 mm shoe-width options.
For a soft-ground application, wider tracks can be considered because they provide a larger contact area. But wider is not automatically better in every project. A wider undercarriage can increase transport width and may require different logistics arrangements.
That is why I prefer to balance three things: ground performance, machine stability, and transport practicality.
LiuGong's official 913E specification lists a maximum digging reach of 8,300 mm and a maximum digging depth of 5,470 mm for the published configuration.
These figures make the machine suitable for many general excavation tasks, but actual reach depends on the boom and arm combination. For deeper dredging or work farther away from the machine, a special long-reach configuration may need to be considered instead.
The current LiuGong 913E page lists a 0.55 m³ standard bucket capacity.
A 0.55 m³ bucket is useful for general excavation and material handling, but bucket choice should always match the material.
Soft mud, wet soil, sand, clay, gravel, and mixed construction material do not behave in the same way. A bucket that is fine for one material may not be the best choice for another.
Wetland machines often work in dirty conditions. Mud gets everywhere. Water, plant material, dust, and sediment can collect around the undercarriage and working equipment.
LiuGong highlights easy-access maintenance points on its 913E product information. The goal is simple: make routine inspection and service easier so the operator does not have to waste unnecessary time reaching filters and service points.
For me, this is not a small detail. A machine that is easier to inspect is easier to keep in working condition.
When customers ask me for specifications, I prefer to show the official reference figures and then explain which parts may change with the wetland configuration.

The figures above are useful for understanding the standard 913E platform. They are not a promise that every LiuGong 913 Wetland excavator will have exactly the same specification.
For example, a LiuGong brochure lists different track shoe widths and different boom and arm combinations. It also gives a 13,800 kg operating weight for one particular 913E configuration, showing why configuration details matter when comparing machines.
This is where I think buyers should slow down a little.
A normal excavator and a wetland excavator may share the same basic engine, hydraulic system, cab, boom, and arm. The difference can be in the way the machine is prepared for the working environment.
| Item | Standard 913E | Wetland-Oriented Configuration |
|---|---|---|
| Track Shoes | 500 mm standard reference | Wider configuration may be considered |
| Ground Condition | Normal construction ground | Soft, muddy or waterlogged ground |
| Ground Pressure | Depends on standard configuration | Configuration aims to distribute load over soft ground |
| Working Area | Roads, farms, construction sites, general excavation | Wetlands, marshes, ponds, riverbanks and drainage areas |
| Transport Width | Based on standard machine | May increase with wider tracks |
| Attachments | Standard or optional attachments | Bucket and special attachments selected according to work |
| Site Assessment | General machine selection | Ground bearing capacity and water conditions become more important |
The wetland column describes a practical project configuration approach rather than a fixed LiuGong factory specification. The actual machine should be confirmed against the customer's site conditions.
I think this distinction is worth making because online machinery listings sometimes make wetland excavators sound almost magical. They are not. A properly configured machine can perform very well in soft ground, but every excavator still has limits.
Wetland construction often involves moving soil in places where the ground is soft and uneven. The excavator may need to create channels, reshape ground, clear unwanted material, or prepare a site for future work.
The key is not just digging power. The machine needs to move safely between work areas without putting excessive pressure on the ground.
Agricultural drainage is a very practical application.
Farmers and contractors may need to clean existing drainage ditches, open new channels, remove sediment, or improve water flow. A LiuGong 913-class excavator can be useful when the project does not require the size of a large 20-ton excavator.
Ponds collect mud and sediment over time. If the pond needs cleaning, an excavator can remove accumulated material and reshape the bottom or banks.
However, I always recommend checking the bank strength before placing the machine close to the water. Soft ground beside a pond can be much weaker than it looks.
Riverbanks are another difficult working environment. The soil can be wet, loose, and uneven. The excavator may be used for bank shaping, sediment removal, drainage work, vegetation clearing, and maintenance.
For these jobs, the operator needs to keep the machine balanced and avoid working too close to unstable edges.
Land reclamation can involve moving large quantities of wet soil and sediment. A suitable crawler configuration helps the excavator work more effectively on soft ground while moving between different areas.
Environmental projects often need careful excavation rather than aggressive digging. The operator may need to remove selected material while protecting nearby areas.
For this type of work, smooth hydraulic control and the correct bucket can be just as important as raw digging force.
Drainage channels, small watercourses, urban landscaping, sewage-related earthwork, and other municipal projects can involve wet or unstable ground.
A medium-size excavator can be useful because it offers a balance between working ability and transportation requirements.
When a customer tells me they need a “913,” I do not stop there. I normally compare the machine with nearby LiuGong models to see whether the size actually fits the job.
| LiuGong Model | Operating Weight | Rated Power | Bucket Capacity | General Position |
|---|---|---|---|---|
| 913E | 13,500 kg | 74 kW | 0.55 m³ | Medium excavator |
| 915E | 14,050 kg | 86 kW | 0.6–0.65 m³ | Medium excavator |
| 915F | 15,600–16,800 kg | 90 kW | 0.65 m³ | Medium excavator |
| 922E | 22,000–23,850 kg | 112–124 kW | 0.45–1.2 m³ | Heavy medium excavator |

This comparison is useful for one reason: it shows that “bigger” is not automatically the answer.
If the job involves narrow access, agricultural drainage, pond maintenance, or relatively light wetland excavation, moving directly to a 22-ton excavator may not be necessary. On the other hand, if the project involves heavy digging, large buckets, deep excavation, or high daily production, a heavier machine may make more sense.
The final decision should come from the job requirements rather than the model number alone.
Supplying a machine is not finished when the excavator is selected.
For an international order, I also need to think about inspection, accessories, documents, packing, loading, shipping dimensions, and the destination port.
Once the model and configuration are confirmed, the production or preparation schedule depends on the machine model, configuration, order quantity, and customization requirements. We confirm the delivery schedule before production or preparation begins.
Before shipment, we inspect the main areas that matter during operation:
Machine appearance
Engine condition
Hydraulic system
Boom and arm
Bucket and linkage
Crawler and undercarriage
Travel functions
Swing function
Basic operating functions
Attachments and accessories
For a wetland excavator, I pay particular attention to the undercarriage because it will carry the machine through the exact environment that created the need for a wetland configuration in the first place.
Operation manuals, standard accessories, spare parts, and required documents are prepared according to the order.
If the customer requests additional attachments, these should be confirmed before shipment. It is much easier to prepare the correct bucket or attachment before the machine leaves than to solve the problem after it arrives at the destination.
International orders are commonly arranged through T/T. A deposit is normally paid before production or preparation, with the balance arranged before shipment according to the agreed commercial terms.
Complete excavators are generally transported by sea. Spare parts and smaller accessories can often be sent by air or express depending on their size, weight, destination, and urgency.
Before loading, the excavator is protected and secured according to transportation requirements. Film or other suitable protection can be used for exposed areas, while loose accessories and spare parts are packed separately in cartons or wooden cases when required.
For wetland excavators with wider tracks, shipping dimensions deserve special attention. The machine may be wider than the standard configuration, so I recommend confirming the final transport width before the freight booking is made.

This is useful when a customer is searching for a LiuGong 913 Wetland Excavator for Sale but is not yet sure about the exact configuration.
I do not think a machinery supplier should simply ask, “How many units do you want?”
I would rather ask:
What kind of soil are you working on?
How soft is the ground?
Is the area permanently wet or only seasonal?
How deep is the water?
How deep do you need to dig?
What material will you excavate?
How far does the machine need to reach?
Do you need dredging equipment?
What bucket capacity do you expect?
Do you need wider tracks?
What is the destination country and port?
These questions tell us much more than the word “913.”
Our international trade team has experience with construction machinery, mining machinery, agricultural machinery, and attachments. We have served customers in Asia, Africa, America, and other international markets.
We can support the process from machine selection and configuration discussion to inspection, documents, packing, and international transportation.
The official LiuGong product information identifies the excavator as the 913E. “LiuGong 913 Wetland excavator” is used on this page as a search and product description for a 913-class LiuGong excavator prepared for wetland applications.
LiuGong's current official 913E product page lists an operating weight of 13,500 kg. Another official brochure gives 13,800 kg for a particular configuration. The difference shows why the exact configuration should be confirmed before an order.
The current LiuGong 913E page lists a standard bucket capacity of 0.55 m³. LiuGong's brochure also provides bucket selection guidance for different working materials and configurations.
It can be considered for wetland applications when the machine is correctly configured for the actual ground conditions. The final setup should take soil strength, water depth, machine weight, track width, working reach, and attachments into account.
Wider track shoes can be considered depending on the machine configuration. LiuGong's official 913E brochure lists 500 mm, 600 mm, and 700 mm shoe-width options. However, wider tracks also affect transport width, so both working conditions and logistics need to be considered.
The official LiuGong 913E page lists a maximum digging depth of 5,470 mm for the published configuration. Different boom and arm arrangements can change working dimensions.
Yes, a suitable excavator configuration can be used for pond, drainage, riverbank, and sediment-removal work. The required boom, arm, bucket, and working reach depend on the depth and distance of the dredging operation.
There is no universal depth limit that applies to every wetland site. Deep mud can vary greatly in strength. Before recommending a configuration, I prefer to know the soil condition, water depth, expected travel path, and working position.
Delivery time depends on the selected LiuGong model, configuration, quantity, and customization requirements. We confirm the expected schedule before production or preparation.
Complete excavators are generally shipped by sea. Spare parts and smaller accessories can be shipped by air or express when suitable.
Yes. Bucket selection should be based on the material, digging conditions, required productivity, and machine configuration. LiuGong also provides bucket selection guidance for the 913E platform.
After working with construction machinery requirements, I have learned that the machine name is only the beginning of the conversation.
A customer may search for a LiuGong 913 Wetland excavator, but what they really need is a machine that can work reliably on their particular site.
If the project involves marshland, wet farmland, ponds, drainage channels, riverbanks, dredging, land reclamation, or environmental work, I first look at the ground. Then I look at the required digging depth, reach, bucket, track width, machine weight, attachments, transport dimensions, and expected workload.
The LiuGong 913E provides a useful 13.5-ton-class excavator platform. LiuGong's current official specifications list 74 kW rated power, a 0.55 m³ standard bucket, 8.3 m maximum digging reach, 5.47 m maximum digging depth, and a 500 mm standard track shoe width.
For wetland applications, the final configuration is what matters. Wider crawler shoes may be considered where appropriate. Different buckets can be selected for different materials. Longer working equipment may be considered for deeper or farther-reaching work. None of these choices should be made without looking at the actual site.
At Ganglong Heavy Industry Technology (Hefei) Co., Ltd. and Hefei Ganglong International Trade Co., Ltd., we can help customers move through that process step by step.
We can discuss the machine, working conditions, configuration, attachments, inspection, accessories, documents, payment, packing, and international shipping before the order is finalized.
If you are looking for a LiuGong 913 Wetland excavator for sale, a LiuGong 913 excavator for soft ground, a LiuGong Wetland excavator for dredging, or a 913E excavator for drainage and agricultural projects, send us the basic working information first.
A few site photos, the soil condition, water depth, required digging depth, expected bucket size, and destination port can tell us a lot.
That is usually the best way to start. Instead of selling you a machine based only on a model number, we can work backward from the job and discuss a configuration that makes practical sense.
Source note: Technical specifications in this page are based on LiuGong's official 913E product information and official 913E brochure. Specifications may vary by market, production version, configuration, and optional equipment. Final specifications should be confirmed against the machine offered for the specific order.
