HY155 ME Amphibious Excavator

Water Conservancy & Dredging Special Amphibious Digger

Hiyo HY155ME is a professional 22.5-ton amphibious pontoon excavator tailored for river dredging and water conservancy projects. The fully sealed anti-corrosion floating chassis enables safe floating operation on shallow rivers and muddy tidal flats without sinking risk. Equipped with 86kW stable low-consumption engine, it supports long-hour continuous aquatic construction. Standard 0.54m³ bucket finishes large-scale silt cleaning, while interchangeable breaker and grapple expand working functions. The 360° rotating upper body operates flexibly in narrow waterways and wetland trenches. Compared with ordinary land excavators, it saves high costs of temporary barges and mud pavement. Widely used in river regulation, reservoir dredging and water environment restoration, HY155ME is recognized by global water engineering contractors for stable floating performance and multi-functional advantages.

Key Highlight Features

1. Fully sealed buoyancy pontoon undercarriage: Adopt high-tensile corrosion resistant steel, realize safe floating operation in shallow river and tidal zones.
2. Low ground pressure design: Large contact area pontoons avoid sinking on marsh, mudflat and soft wet soil terrain.
3. Powerful 86kW industrial engine: Stable power output, low fuel consumption, adapt long-hour aquatic continuous work.
4. Multi-attachment compatible hydraulic system: Quick change interface for bucket, hydraulic breaker, wood grapple, vibratory hammer.
5. Full anti-corrosion protection: Chassis, track and hydraulic pipeline adopt waterproof anti-rust coating for long water service life.
6. 360° full rotation upper body: Flexible operation without dead angle in narrow waterway and marsh areas.
7. Stable traveling hydraulic drive: Synchronous track drive system ensures balanced movement on water and mud ground.
8. Wide working coverage: Fit water conservancy, port dredging, wetland restoration and tidal flat development.

Performance Advantages

1. Dual land & water working capacity: Eliminate temporary barges or mud access mats, cut extra construction cost greatly.
2. Excellent anti-sink performance: Oversized sealed pontoons disperse machine weight evenly on soft mud and shallow water.
3. Versatile multi-tool operation: One machine completes dredging, rock breaking, timber handling and foundation compaction.
4. Long-lasting waterproof structure: Sealed pontoon chambers prevent water infiltration, reduce daily maintenance frequency.
5. Stable floating balance: Optimized weight layout avoids rollover during side digging on water surface.
6. Energy-saving power matching: Engine and hydraulic system coordinated to lower fuel consumption under long aquatic shifts.
7. Simple transfer: Detachable pontoon design for land transportation by standard flat truck.
8. Strong terrain adaptability: Pass swamp, tidal flat, lake shoal and muddy riverbank smoothly.
