Types of Amphibious Excavators

Amphibious excavators are hydraulic excavator machines transformed with specialized floating devices to enable them to work on marshy grounds and water bodies. Here are some common types of amphibious excavators:

Amphibious Dredging Excavator

This type of excavator has a stable undercarriage that usually consists of parallel pontoons or tracks designed to work efficiently in shallow water depth. These excavators are applicable in dredging tasks like deepening or widening rivers, lakes, or canals. They are also used for removing sediments, checking the maintenance of underwater structures, and excavating the seabed.
Amphibious Harvester Excavator

An amphibious harvester excavator is specially designed for environmental and agricultural tasks in challenging wetland conditions. Such tasks may include harvesting aquatic biomass, preparing land in marshy areas, or maintaining water quality by removing excess vegetation. The unique feature of this kind of excavator is flexible harvesting heads or specialized attached tools for wetlands and water bodies. These heads allow for precise extraction without disturbing the ecosystem.
Amphibious Material Handling Excavator

Material handling excavators come with a long-reach arm fitted with grab buckets or other sorting attachments. They are suitable for sorting and transferring materials like sediment, stones, debris, or waste either from the seabed or the shore. Such operations usually involve incident demolition, land reclamation, and coastal protection.
Amphibious Drilling Excavator

This type of excavator is usually coupled with a drilling system. An amphibious drilling excavator can carry out underwater trenching/ drilling tasks, boreholes from the water surface, or pipeline laying in marshy grounds. Such tasks may include offshore oil extraction, marine construction, or geological surveying.
Mini Amphibious Excavator

Just like the name suggests, a mini amphibious excavator is a smaller version of the amphibious excavator. This type of excavator is well suited for working in areas with restricted access, narrow channels, or delicate environments where larger machines may cause significant disruption or environmental damage.

Specification and Maintenance

The following excavator amphibious specs need to be kept in mind when discussing their maintenance requirements:

Motors Power

Motors provide a thrust of over 600 HP. This power enables the amphibious excavator to work in open water bodies with a current or tide. Despite the rugged use of the engine, maintenance is not very exhaustive or technical.
Hydraulic System

The amphibious excavator consists of a hydraulic system that has hoses and pumps. Hoses transport oil to different buckets and attachments. The hydraulics push the system in a balanced manner to operate other equipment, such as the dredging cutter head. The oil tanks hold up to 2,000 liters of hydraulic oil. The hydraulic cylinders may have a capacity of around 210 liters per cylinder (if they contain oil). Regular cleaning of cylinders, hoses, and pumps is essential to avoid any blockages. The hydraulic oil should be changed frequently as per the usage to ensure smooth operation.
Excavator Dredge Runners

Runners are often made of steel and have a length (or diameter if circular) of approximately 1.5 to 3 meters. These often bear the most damage from land use, sediment, corrosion, and water pressure. Lubrication of all moving parts is essential for smooth running and avoiding land wear and tear.
S Recent Developments

The S-dredger runner design is becoming popular. It has an innovative design that reduces resistance while moving and works efficiently in deep water. It is ideal for dredging in large riverbeds or deep trenches and stays stable at all depths. More studies are being done to improve runner designs further.

Additional Care:

Cleaning: Bombardier amphibious excavators have sediment that can damage the machine quickly. Regular washing with freshwater can remove this material and reduce any corrosion.
Lubrication: Lubrication of all moving parts should take place to ensure smooth running and minimal wear and tear.
Oil Changes: As per the excavator's working hours, the hydraulic oil and oil for the motor should be changed. This ensures that filthy oil does not hinder the smooth running of any part of the machine.
Greasing: All grease points should be greased regularly to reduce any wear and tear and extend the machine's life.

The above are some basic excavator amphibious specifications and their maintenance requirements. People can add more care tips by studying the excavator closely after using it in water and on land for some time.

Scenarios of using an amphibious excavator

Here are some common applications of the excavator:

Dredging and desilting

The main use of the amphibious excavator is for dredging.

Operators move the machine onto the water body and use it to remove silt or sediment from the river bed.
Channel and pond excavation

In addition to dredging, the amphibious excavator can also be used to expand and deepen existing channels and ponds.

When doing this kind of task, operators prefer to use the smaller excavators. They use them to deepen storm water management ponds, irrigation canals, and retention ponds.
Wetland maintenance and rehabilitation

Amphibious excavators are preferred machines for carrying out wetland maintenance and rehabilitation tasks.

Its ability to navigate water and land makes it the ideal machine for digging and clearing drained and wetland marsh areas.
Land clearing

Land clearing is another major use of the amphibious excavator.

The excavator driver can move the machine through woodlands, marshy, and swampy areas to clear unwanted vegetation.

In this type of land clearing use, the excavator is usually fitted with a tree shear attachment.
Demolition

Amphibious excavators can also carry out demolition tasks in waterways and along waterway banks.

They are used to demolish structures like damaged piers, docks, and bridge abutments.
Project mobilization

The excavator can also be used to transport materials like gravel, sand, and soil to and from project sites.

Sometimes, the excavator can be used as a support machine for offshore projects like renewable energy, marine construction, and underwater pipeline installation.

How to choose an amphibious excavator

It is vital to take some factors into account to select the suitable amphibious excavator model for specific application needs and working circumstances. These factors may strongly affect what type of amphibious excavator is appropriate for one's use.

Working environment: This is one of the most important factors to consider when choosing an amphibious excavator. Working environments can be land-locked, water-locked, or swampy. Different types of amphibious excavators fit different scenarios. For example, those who work in water or swampy areas may need to choose an amphibious excavator with a powerful wading depth and good floating performance.
Handling capacity: Some situations may require the excavated objects to be heavier or the excavated quantity to be larger. In such a case, buyers need to choose an amphibious excavator with a proper load capacity and a specially designed bucket.
Engine power: Working in different terrains and conditions may require different engine power. Buyers should choose an amphibious excavator with sufficient engine power to ensure smooth operation in their specific working environment.
Functions and attachments: Different models of amphibious excavators may have different working attachments, such as drag buckets, rake buckets, and dredging heads, which suit different work types. Buyers should choose the appropriate model and attachment according to their work demands.
Main dimensions: This factor includes the boom length, arm length, bucket width, and vehicle body length. Buyers need to choose the proper model and size according to their working spaces and requirements.
Transportation: For some users, an important consideration is the ease of transport. This factor can be crucial for those who need to frequently move the excavator from one location to another.
