by What are Amphibious Excavator?
Amphibious diggers are large excavating machines that have the capability to travel over land and water. They are equipped with large tracks or wheels that allow them to operate on land and in water. On land, the excavator moves around just like regular construction equipment using its tracks or wheels. However, when in water, it uses propulsion systems like propellers mounted on the chassis to maneuver.
Key Components of Amphibious Excavator
Amphibious diggers consist of certain key components that enable their amphibious operation:
– Tracks/Wheels: Most Amphibious Excavator diggers are equipped with very large tracks or oversized wheels to support their weight both on land and in water. The tracks also act as the primary means of propulsion on land.
– Buoyancy Compartments: Sections of the chassis are divided into buoyancy compartments that provide floatation when the machine is in water. This allows the excavator to remain stable and afloat.
– Propulsion System: In water, excavators rely on propulsion systems like propellers mounted at the rear or sides to move forward, backward or steer. Common systems include single or twin propeller configurations powered by diesel engines.
– Waterproof Components: Critical components inside the excavator housing are sealed and waterproofed to prevent water damage when submerged. This includes the engine, electronics, pumps, hydraulics etc.
– Navigation Aids: Some advanced models have GPS systems, sonar, depth sounders and cameras to assist navigation and working in low visibility underwater conditions.
Applications of Amphibious diggers
Thanks to their unique amphibious capability, excavators find varied applications across different industries:
Coastal and Marine Construction: Amphibious diggers are extensively used in coastal and marine construction projects involving land reclamation, dredging, harbor development etc. Their ability to operate both on land and water makes them very suitable for such projects.
Flood Control and River Management: During floods, these machines play a vital role in building flood walls, strengthening banks, clearing debris and restoring river Channels. Their mobility allows working even in flooded areas with minimal land access.
Oil and Gas: In offshore oil rigs and pipelines, amphibious diggers perform tasks like preparation of drilling platforms, laying pipelines, trench digging work near shorelines etc.
Mining: Riverbed mining, marine aggregate extraction and other such water-based mining activities use amphibious diggers for dredging and material handling purposes.
Emergency Services: Their unique capabilities also make amphibious diggers valuable assets for flood relief work, disaster recovery operations and removing debris in flood-struck areas with minimal overland access.
Benefits of Using Amphibious diggers
There are several advantages that make amphibious diggers a preferred choice for engineers and contractors involved in coastal, riverine or marine construction projects:
– Both On-land and Offshore Mobility: With the ability to seamlessly transition between land and water operations, they provide unmatched access to work sites located near or over water bodies.
– Continuous Working: Projects aren’t delayed even during high tide cycles as the excavator doesn’t have to be moved entirely out of water between tides.
– Cost Effectiveness: Amphibious diggers help reduce project timelines and costs compared to conventional equipment by avoiding heavy lifting/launching costs during frequent on-land, offshore transitions.
– Safety: Working near water with amphibious diggers is safer than with conventional land equipment which has risks of toppling into water.
– Environment Friendly: They cause minimal pollution or damage to riverbeds compared to repeated movement of heavy lifting machinery.
– Versatility: A single amphibious digger can perform multiple on-land and offshore tasks like dredging, reclamation, material handling etc. efficiently.
– Stability: Their wide tracks and pontoon-like chassis provide outstanding stability even in choppy waters and underwater working conditions.
While amphibious diggers have a higher upfront cost than regular construction equipment, their unique capabilities and productivity benefits help lower overall project costs, especially for coastal and marine infrastructure jobs. As coastal urbanization increases globally, the demand for such versatile construction machines will continue rising.
Amphibious diggers present an indispensable solution for contractors and engineers involved in port and harbor development, flood management, offshore oil & gas projects and myriad other construction activities near or over water bodies. Their ability to seamlessly operate in both terrestrial and aquatic environments makes them highly productive and cost-effective for a wide range of coastal and riverine infrastructure development works
