Our marsh buggy/amphibious excavator Undercarriages can adapt to various brands and models of upper excavators, Ranging from 5 tons to 40 tons.


1.Specialized Track Shoes Material:
as the most imperative wear part, the track shoe cleats we produce are of China WISCO's super high strength welding structure steel HG785D whose yield and tensile strengths are 685MPa and 785MPa respectively.

2.Track Chain Roller
We choose 40Cr steel (DIN 41Cr4) for our track chain rollers which are one of the most critical wear parts during the excavator's daily operation. All Rollers must be put through heat treatment including quenching and tempering to Enhance the hardness to HRC50-56.

3.Wear Pad for Resistance
to ensure the wear pad would not be easily worn out by the track chains, We chose a special wear-resistant material NM400 for longevity. A high-quality Material selection will extend the pontoon's lifespan by 1-2 years on average.

4.Screws Adopted for Amphibious Excavator
All screws equipped on our swamp buggy are treated with the Dacromet process and must go through a salt spray test which lasts for 1000 hours. this Highly improves the anti-corrosion ability of the screws, and thus allows the Excavator to work longer in a more severe working environment. the maintenance and replacement cycle of spare parts are thus extended.

5.Hydraulic Oil Pipes & Fittings
the hydraulic oil pipe and fittings are imported from well-known brands with Good durability, and the external surface of all oil pipes is coated with a Protective layer of PVC to enhance their wear-resistant and corrosion-resistant Properties. A tidy layout is maintained for all oil pipes in an orderly manner.

6.Guide&Drive Wheel Heat Treatment
to ensure reliable hardness and strength, both the front idler and drive Sprocket of the PONTOON are specially heat-treated.

Production Process

1.High-precision equipment, excellence, Quality Assurance.
2.Robotic Welding of Pontoon Undercarriage.
3.More than ten years of welding experience, meticulous and precise.
4.the sandblasting process removes rust strongly, Each pontoon must go through shot blasting till Sa2.5 grade with surface roughness within 30-70um Before getting coated.
5.Special paint for marine ships, the thickness of coating layer must Achieve 160~200um and each pontoon must have 2 layers of primer and two layers of top coats.
6. Each H frame is machined as a whole by a gantry type machining Center and the circle of bolting holes are milled by the hole milling machine.
7. Heavy duty processing equipment, better processing skills.

the Advantages of Amphibious Excavator/Marsh buggy excavator undercarriages Fabricated by RIVER:

1.Patented technology and ISO9001 quality certificated.
2.Customized pontoon undercarriage, to meet various construction projects.
3.Increased height of the chain plate, reinforced track chain and Anti-corrosion.
4.Designed support bar inside the chain plate, more load capacity Durability.
5.Modular design facilitates transportation and on-site installation.

What Are the Characteristics of the Amphibious Excavators Produced by River?

: in general, the buoyancy of the floating pontoon we designed is less than the weight of the whole vehicle(amphibious excavator), which makes the amphibious excavator not float when working in shallow or deep water, so that it's more stable during work; if the equipment need to be carried out construction work in deep water environment, it is necessary to add side floating pontoon or positioning pile device.

Durability: the internal skeleton of the floating/side pontoon is meticulous, making the entire floating pontoon structure more stable, and the overall structure of the floating pontoon is still intact even after a few years of use; the track shoe of the amphibious excavator is made of HG785 high-strength steel plate, and the internal reinforcement plate technology is adopted to ensure the strength of track shoes is higher and not easy to deform; in addition, we also add wear strips on the contact surface between the floating pontoon and the roller to effectively prevent the wear of the pontoon undercarriage caused by long time touch with the sprocket.

Reliability: the screws installed on the amphibious undercarriage are treated with Dacromet process, which is not easy to rust and more durable; the hydraulic oil pipes and joints are from high-quality imported brands, and the oil pipes are made of 4-layer pipe technology, which is durable and not easy to burst or crack.
