حفار برمائي Caterpillar 320C

Our factory offers standardized refurbishment of Caterpillar 320C amphibious excavators. Featuring the classic 3306 direct-injection engine, it's compatible with even low-quality fuel. The custom-made, thickened, sealed pontoon hull is specifically designed for wading, swamp, and tidal flat operations, making it irreplaceable by ordinary land excavators. Complete refurbishment and overhaul of the entire machine provides significantly better value than brand-new amphibious excavators, making it a top-selling choice for river dredging and tidal flat development.

Equipped with a standard 0.92m³ earthmoving bucket, this machine boasts a maximum excavation depth of 5.95m, enabling versatile operations in lake dredging, river channel clearing, tidal flat reclamation, wetland infrastructure construction, and coastal cofferdam construction. Its custom-designed fully sealed floating pontoon provides ample buoyancy reserves, allowing for all-weather floating operations. It remains secure in shallow water and silt-filled swamps, offering dual-mode operation for both land and water. The original Caterpillar hydraulic system has been refurbished and overhauled, with all seals replaced, ensuring smooth, consistent operation and precise control during heavy-duty silt excavation and slope trimming. The classic direct-injection engine features a simple structure and extremely low failure rate, making maintenance in remote overseas areas easy and accessible to local technicians, ensuring uninterrupted work without delays.

The boom and stick are reinforced with high-strength steel plates through flaw detection and welding, with all cracks repaired, ensuring no deformation under heavy-load excavation. The amphibious pontoons are constructed from thickened, wear-resistant marine steel plates, integrally welded, with multiple sealed compartments for watertight protection, corrosion and anti-corrosion treatment, making them resistant to water immersion and corrosion, and ensuring a long service life. The entire machine undergoes sandblasting for rust removal, followed by a double-layer protection with original Caterpillar yellow paint and a clear varnish, ensuring no paint peeling or rust during long-term outdoor water operations. Extended and reinforced track plates enhance wear resistance, preventing entanglement with aquatic plants and silt in amphibious applications. The refurbished walking mechanism eliminates deviation and chain slippage issues.

We cater to overseas river dredging companies, coastal reclamation contractors, wetland restoration project owners, fishpond and reservoir dredging contractors, swamp and tidal flat infrastructure construction teams, and waterway engineering leasing companies; specializing in overseas clients undertaking special construction projects in water-based and silt-prone soft soil conditions.

The entire machine is refurbished and tested under full load on both land and water. A complete list of refurbished and replaced parts is provided, and all maintenance procedures are traceable. The engine and hydraulic core components are covered by a warranty, and remote troubleshooting guidance is available. The pontoon structure welding is guaranteed, eliminating the risk of leaks. Hydraulic breakers, grab buckets, and weed cutters can be added as needed. All customs documents are complete, and full container shipping is supported. On-site testing and inspection are available at our domestic warehouse.
