by Amphibious diggers, also known as amphibious diggers, are a unique type of heavy construction equipment that is capable of performing excavation and loading tasks both on land and in water. These vehicles have the ability to smoothly transition between land and aquatic environments, making them highly versatile for a wide range of infrastructure and civil engineering projects.
Key Features of Amphibious Excavator
Amphibious diggers are designed with some important features that allow them to operate on both land and water.
Tracks and Propulsion System
Amphibious Excavator diggers are tracked vehicles similar to regular excavators used on land. However, they also have powerful water jets or propellers installed at the rear end for propulsion in water. The tracks provide traction on land while the rear propulsion helps maneuver and move the vehicle when partially or fully submerged in water.
Buoyancy and Stability
The hull design of amphibious diggers incorporates air chambers or floats to provide buoyancy when the vehicle is in water. Additional weights are also installed to increase stability on land and prevent the vehicle from tilting too much during excavation tasks.
Seals and Waterproofing
All areas containing mechanical and electrical components are sealed tightly to prevent water ingress. Waterproofing is done to protect sensitive parts from getting damaged even when the excavator is fully submerged for prolonged periods.
Applications of Amphibious diggers
Coastal and Riverbank Construction
Amphibious diggers are ideal for infrastructure projects located along coastlines or river banks. They can easily access construction sites that regular land excavators find difficult to reach due to the water barrier. Tasks like reclamation, dredging, bank reinforcement etc. can be performed efficiently.
Flood Control and Restoration
After floods, amphibious diggers play a crucial role in restoration work like clearing debris, digging temporary channels and rebuilding embankments. They provide quick access across submerged areas to speed up relief operations.
Marine Construction
In marine environments like construction of offshore ports, drilling platforms etc., amphibious diggers exhibit unmatched versatility. They operate freely on the marine worksite, barges as well as on the mainland for transporting materials.
Main Types of Amphibious diggers
There are two main types of amphibious diggers available in the market:
Floating Excavators
As the name suggests, floating excavators stay afloat on water with the help of integrated foam-filled floats or air chambers. They are often lighter and have lower ground pressure compared to swimming excavators. Floating excavators work best in shallow waters with uniform bottom conditions.
Swimming Excavators
Swimming excavators are heavier duty machines designed for working in deeper waters. They rely on rear propellers for propulsion rather than buoyancy. Swimming excavators can fully submerge themselves underwater during operation, making them suitable for jobs requiring greater mobility and underwater reach.
Buying Considerations for Amphibious diggers
There are some key factors to evaluate when purchasing an amphibious digger:
– Intended work environment – Marine, riverine or both. Depth of operations.
– Required tasks – Dredging, backfilling, debris clearance etc.
– Engine power- Higher hp for heavy-duty projects in deep waters.
– Maximum excavator reach – Consider boom and stick length.
– Transport options – Self-propelled or trailer mounted.
– Safety features – Foam filled pontoons, lighting, stability aids etc.
– Aftersales service and spare parts availability.
– Lifecycle cost including fuel efficiency and resale value.
Amphibious diggers have established themselves as a indispensable equipment in coastal, flood control and marine projects due to their unique ability to work seamlessly on land and water. With advancements in propsulsion, sealing and stability technologies, they continue to get more powerful and versatile to take on tougher jobs in diverse wet infrastructure sites. Proper selection based on intended use ensures owners reap maximum productivity from these do-it-all machines.
