The HEKING HK300SD Amphibious Excavator is a professional heavy-duty excavating machine specially developed for wetland construction, river dredging, flood control projects, coastal engineering, and oil & gas pipeline installation in difficult soft-ground environments. Built with reinforced pontoons and a specialized amphibious undercarriage system, this amphibious excavator delivers excellent stability, flotation performance, and operational efficiency in marshes, swamps, muddy terrain, shallow water, and low-bearing-capacity ground conditions.
Designed for the Europe and Middle East construction and infrastructure markets, the HK300SD combines reliable hydraulic performance, strong structural durability, and efficient excavation capability. The machine is widely used by contractors, dredging companies, government engineering projects, and oil & gas infrastructure developers requiring dependable operation in challenging terrains where conventional excavators cannot work efficiently.
The HK300SD features a reinforced amphibious pontoon undercarriage system designed to provide superior buoyancy and operational stability. The large pontoons significantly reduce ground pressure to only 0.14 kg/cm², enabling the machine to travel smoothly across wetlands, swamp areas, soft clay, marshlands, and shallow water environments without sinking.
The machine adopts a triple-chain undercarriage structure for improved durability and better traction performance in muddy conditions. Reinforced track shoes and chains increase resistance to wear, corrosion, and deformation during continuous operation in abrasive environments.
Its wide overall operating width and stable pontoon structure help maintain machine balance during digging, lifting, and traveling operations, even under difficult site conditions.
The HEKING HK300SD Amphibious Excavator is equipped with a Mitsubishi 4M50-TLC3J turbocharged diesel engine delivering stable power output for demanding excavation tasks. Combined with dual Doosan T5V112 variable plunger hydraulic pumps, the machine provides efficient hydraulic response, smooth operation, and strong digging force.
The PARKER AV280 hydraulic valve system ensures precise hydraulic control and high operational reliability, while the Eaton swing motor and DOOSAN travel motors improve machine maneuverability and working efficiency.
The advanced hydraulic configuration allows the excavator to perform efficiently in river dredging, canal maintenance, embankment reinforcement, and coastal infrastructure projects.
The HK300SD is widely used in river dredging and waterway maintenance projects where standard excavators cannot access. Its amphibious structure enables operators to perform excavation and sediment removal directly in shallow water or muddy areas.
For coastal engineering projects, the machine is suitable for shoreline reinforcement, tidal area maintenance, seawall construction, and marine infrastructure development. The excavator's stable flotation system and strong digging performance allow efficient operation in continuously wet environments.
The optional additional pontoon and spud system can further improve machine stability in deeper water applications.
The HK300SD Amphibious Excavator is highly suitable for oil & gas pipeline installation projects crossing wetlands, marshes, and swamp regions. The machine can travel safely over unstable ground while maintaining reliable digging performance for trenching, backfilling, and material handling operations.
Its low ground pressure minimizes environmental impact and reduces terrain damage during pipeline construction projects, making it an effective solution for environmentally sensitive areas.
HEKING focuses on manufacturing durable amphibious excavators capable of long-term operation in harsh environments. The HK300SD uses high-strength steel materials, reinforced pontoons, and corrosion-resistant structural components to improve machine lifespan and reduce maintenance requirements.
The hydraulic and powertrain systems are selected from internationally recognized suppliers to ensure component availability and long-term reliability for overseas customers.
With simplified maintenance access and robust engineering, the HK300SD helps reduce downtime and operational costs for contractors and fleet owners.
HEKING provides professional export support for customers across Europe, the Middle East, Southeast Asia, Africa, and South America. The HK300SD Amphibious Excavator is available with customized configurations based on project requirements.
Production time is typically within 40 days after receipt of down payment. Payment terms are T/T 30% down payment with 70% balance before delivery.
The company also provides technical support, spare parts assistance, and international logistics coordination for global buyers.
