Brand: Doosan – A world-leading South Korean heavy equipment manufacturer with 50+ years of excavator R&D and production experience, renowned for rugged construction, powerful performance, and cost-effective after-sales support. Doosan machinery dominates the amphibious excavator market in Southeast Asia, the Middle East, and Africa, trusted by coastal engineering, river management, and aquaculture enterprises for its exceptional adaptability to wetland, shallow water, and marine environments.
Model: Doosan DX215 Amphibious Excavator (Marine Customized Version) – A 21-ton-class professional water-land dual-use excavator, upgraded from the classic DX215-9C with a reinforced floating pontoon undercarriage and anti-corrosion components. Equipped with a Doosan DL06P turbocharged diesel engine, it excels in coastal dredging, river channel cleaning, tidal flat reclamation, and shallow sea construction tasks, delivering unmatched stability and efficiency in harsh marine environments.
- Operating Weight: 23,500kg (including floating pontoon undercarriage)
- Engine: Doosan DL06P 6-cylinder turbocharged intercooled diesel engine; rated power 110kW @ 2000rpm; peak torque 560N·m @ 1400rpm; compliant with Tier 2/EU Stage II emission standards; marine-grade anti-corrosion treatment for cylinder block and exhaust system
- Undercarriage: Reinforced steel floating pontoon (width 3200mm); sealed track chain with rubber pads; maximum floating depth 1.8m; land travel speed 3.2/5.5km/h; water travel speed 1.2km/h; pontoon anti-collision rubber strip for coastal rock zone operation
- Working Device: Standard 1.0m³ marine-grade bucket (high manganese steel, wear-resistant); maximum digging depth 6.2m; maximum digging radius 9.8m; maximum dumping height 6.5m; optional long-reach arm (15m) for deep-water dredging
- Hydraulic System: Doosan proprietary load-sensing hydraulic system; working pressure 34.3MPa; main pump displacement 2×123cc/rev; swing speed 12.5rpm; arm speed 5.2m/s (lifting)
- Anti-Corrosion Configuration: Full-body marine epoxy coating (180μm thickness); galvanized steel for electrical components; stainless steel bolts and hinges; waterproof cab with IP67 protection rating
- Operator Cab: ROPS/FOPS certified; air suspension seat with lumbar support; air conditioning (standard); waterproof touchscreen monitor; rearview camera + 360° surround view system; cab noise ≤78dB(A)
- Fuel & Fluid Capacity: Fuel tank 320L; hydraulic oil tank 150L; engine oil capacity 18L; coolant capacity 25L; pontoon buoyancy reserve ≥20% (for overload operation safety)
- 3200mm Wide Floating Pontoon: The reinforced steel pontoon distributes weight evenly, ensuring stable floating in 1.8m-deep water without sinking, suitable for tidal flats, swamps, and shallow coastal areas where land excavators cannot access. The anti-collision rubber strip on the pontoon edge prevents damage from rocks and ship hulls during coastal operations.
- Dual-Mode Travel System: Smooth switching between land and water travel—3.2/5.5km/h land speed meets short-distance relocation needs; 1.2km/h water speed ensures safe navigation in slow-flowing rivers and coastal waters, eliminating the need for additional transportation vessels and reducing project costs.
- Marine-Grade Working Device: The 1.0m³ high-manganese steel bucket resists corrosion from seawater and sediment wear, with a service life 30% longer than standard buckets. The optional 15m long-reach arm extends the maximum digging depth to 9.5m, ideal for large-scale river dredging and port channel maintenance.
- Doosan DL06P Engine: The 6-cylinder turbocharged engine delivers strong low-speed torque, easily handling heavy-load digging and dredging tasks in soft soil and sediment. The marine-grade anti-corrosion treatment protects key components from seawater erosion, ensuring stable operation even in long-term coastal work scenarios.
- Load-Sensing Hydraulic System: The system adjusts flow and pressure according to working conditions, minimizing energy waste and improving operation precision. The synchronized movement of boom, arm, and bucket reduces cycle time by 15% compared to conventional hydraulic systems, boosting daily work efficiency by up to 200m³ of dredged material.
- Comprehensive Marine Anti-Corrosion Protection: Full-body epoxy coating, galvanized electrical parts, and stainless steel fasteners form a multi-layer anti-corrosion barrier, effectively resisting salt spray, seawater immersion, and sediment abrasion. The waterproof cab (IP67 rating) ensures electrical components work normally even in heavy rain and splash conditions.
- Intelligent Safety Monitoring: The waterproof touchscreen monitor displays real-time data including engine temperature, hydraulic pressure, and pontoon buoyancy status; automatic alarm triggers when the water depth exceeds the safe limit or the hydraulic system malfunctions. The 360° surround view system eliminates blind spots during water navigation, preventing collisions with hidden obstacles.
- Operator Comfort Optimization: The air suspension seat and air conditioning system create a comfortable working environment for long shifts in hot and humid coastal areas. The ergonomic control layout reduces operator fatigue, and the low-noise cab design improves concentration during high-intensity operations.
- Modular Component Design: Key components (engine, hydraulic pump, swing motor) are modularized for easy disassembly and replacement, reducing maintenance time by 25%. The centralized lubrication system simplifies daily maintenance, and the pontoon track chain has a service life of 5000+ hours under normal operation.
- Global After-Sales Network: Doosan has 200+ authorized service centers and 15 regional parts warehouses worldwide (Singapore, Dubai, Johannesburg, etc.). Marine-specific spare parts (pontoon rubber strips, anti-corrosion buckets) can be delivered within 7-15 days, and on-site technical support is available within 72 hours in major coastal cities.
- Coastal Dredging & Port Construction: Dredging port channels, deepening berths, and cleaning sediment in coastal harbors to ensure safe ship navigation.
- River & Lake Management: Cleaning river channels, removing aquatic weeds, and excavating flood control ditches to improve water flow and prevent flooding.
- Tidal Flat Reclamation & Aquaculture: Reclaiming tidal flat land for agricultural use, and excavating ponds for shrimp, crab, and fish farming in coastal areas.
- Wetland Restoration & Environmental Engineering: Restoring wetland ecosystems, excavating artificial lakes, and building ecological embankments in nature reserves.
