Professional Swamp Excavator for Wetland Engineering

The HK200SD swamp excavator is a professional amphibious excavator specifically designed for soft ground, wetlands, marshes, shallow water, and river dredging operations. Built for contractors and engineering companies working in challenging terrain, this machine combines excellent flotation capability, stable hydraulic performance, and reliable structural durability.

Traditional excavators often experience sinking, instability, and mobility limitations when operating on muddy or waterlogged terrain. This swamp excavator solves these problems through a specially designed pontoon undercarriage system with low ground pressure and large buoyancy capacity. The machine can travel efficiently across wetlands, marshland, soft clay, peat soil, and shallow water conditions while maintaining operational stability.

With an operating weight of 20 tons and a maximum digging reach of 10.8 meters, the excavator is suitable for medium and large-scale dredging and wetland construction projects throughout Europe, the Middle East, Africa, and Southeast Asia.

Product Advantages

  • Designed for swamp, marsh, and wetland excavation projects

  • Large buoyancy pontoons improve floating stability

  • Four travel motors enhance traction in muddy conditions

  • Extendable undercarriage increases operational balance

  • Reinforced chains and track shoes improve durability

  • Low ground pressure reduces sinking risk on soft terrain

  • Reliable hydraulic system ensures smooth operation

  • Suitable for dredging, flood control, and pipeline projects

  • Optional deep-water accessories available for customized work

Efficient Hydraulic System and Reliable Powertrain

The excavator is powered by a Mitsubishi 4D34 turbocharged diesel engine, delivering stable output and fuel-efficient operation for long working hours. The engine provides 70 kW at 2200 rpm, ensuring sufficient power for demanding excavation applications in swampy environments.

The hydraulic system uses a DOOSAN T5V63 variable plunger pump combined with PARKER AV170 control valves for precise hydraulic response and smooth machine control. This configuration improves digging efficiency, travel performance, and operational accuracy.

The four DOOSAN TM22VC travel motors distribute traction power evenly across the undercarriage system. Compared with conventional crawler excavators, the four-motor configuration significantly improves mobility and reduces the risk of slippage on muddy terrain.

The strengthened track shoes and reinforced chain system are engineered for heavy-duty applications and continuous exposure to abrasive materials such as sand, sludge, clay, and gravel.

Floating Pontoon Undercarriage for Soft Ground Stability

The large pontoon undercarriage provides excellent flotation performance and low ground pressure operation. The swamp excavator can move safely across unstable surfaces where traditional tracked excavators may become trapped.

The extendable undercarriage improves working stability and transportation flexibility. Customers can choose between manual extendable or hydraulic extendable undercarriage configurations according to project requirements and operating preferences.

Key undercarriage advantages include:

  • High buoyancy floating pontoons

  • Low ground pressure design

  • Reinforced chain structure

  • Heavy-duty track shoes

  • Improved lateral stability

  • Strong adaptability to muddy environments

The optional additional pontoon and spud system allows the machine to perform in deeper water applications and more demanding dredging environments.

Ideal for Multiple Industrial Applications

This swamp excavator is widely used in various industries where conventional excavators cannot operate efficiently.

Common applications include:

  • River dredging projects

  • Wetland restoration work

  • Flood control engineering

  • Coastal maintenance projects

  • Irrigation canal cleaning

  • Oil and gas pipeline construction

  • Marsh excavation

  • Pond and lake maintenance

  • Environmental remediation projects

  • Waterway development work

The excavator is especially suitable for contractors involved in infrastructure construction and environmental engineering projects across Europe and the Middle East.

Designed for International Buyers and Contractors

The HK200SD swamp excavator is developed for international B2B customers requiring reliable equipment performance, reduced maintenance costs, and flexible customization options. The machine is easy to transport, operate, and maintain, making it suitable for rental companies, contractors, and engineering firms.

The excavator can be customized with optional pontoons, spuds, and additional attachments depending on project conditions.

Production time is generally within 20 days after receiving the down payment, helping customers reduce project waiting time and equipment procurement delays.

Payment terms are 30% T/T deposit and 70% balance before delivery.
