- Long Reach Booms: Available in lengths from 9 to 13 meters for versatile excavation tasks.
Descriptions of 18-22 Ton Amphibious Excavator
According to our sales data in the past few years, 20ton class amphibious excavators have been the best seller. They are widely used for dredging, landscaping, and deepening of river deltas, etc. RIVER’s customized model of RS215-A pontoon undercarriage can perfectly match 18-22 ton swamp excavators. Its standard design allows its independant maximum working depth of within 1.8 meters. Professional in fine machining, River also manufactures and provides alternative long reach booms ranging from 9 meters to 13 meters long.
On many occassions, this model of excavators are appointed for more complicated construction tasks, especially in 2-4m deep water area. Over the years we have been providing our customers with 2-piece hydraulic spuds solution to fix and stablize the excavating platform to ensure both working efficieny and safety. However, slight shaking during digging movement is still unavoidable, while this is the common difficult problem many competitors from both home and abroad are facing. In 2021, in response to demands of our customers, RIVER’s new generation of 4 hydraulic spuds solution finally came out–the 4 pieces of pile spuds are driven by 4 independant hydraulic motors. The operator only needs to press the putton in the cabin to automatically switch on the spud’s streching out and standing up which are both realized by oil cylinders. Thus the excavator undercarriage’s operating stability is further improved and the overall safety condition is better secured. RIVER has already applied for a patent for this typical design.

Applications of 18-22 Ton Amphibious Excavator
- Deep Water Dredging: Ideal for dredging rivers, lakes, and canals, this excavator excels in deep water tasks. Its amphibious design allows it to operate effectively in deeper water, efficiently removing sediment and debris to maintain and expand waterways.
- Wetland Landscaping: This excavator is perfect for large-scale landscaping projects in wetlands and marshy areas. Its stability and flexibility in challenging water conditions ensure precise land shaping and site preparation.
- River Delta Deepening: Suitable for deepening river deltas, this excavator operates efficiently in water depths ranging from 2 to 4 meters. It is crucial for modifying river channels and managing sediment, which aids in flood control and improving water flow.
Benefits of Using Hydraulic Spuds:
- Enhanced Stability: Hydraulic spuds provide additional stability during operation, reducing the risk of tipping or swaying in deep water and soft terrain. This ensures safer and more stable performance.
- Precision Operation: With hydraulic spuds, the excavator maintains a level position in complex terrains, enabling precise excavation and task execution.
- Increased Efficiency: The use of spuds improves operational efficiency by stabilizing the excavator in challenging conditions, minimizing equipment wear and maintenance needs.
