Today, let’s take an in-depth look at the powerful functions of this type of equipment and the key concerns of customers from different countries.

I. What Jobs Can Medium-sized Amphibious Excavators Do?

1. In the Field of Water Conservancy Projects: In river dredging operations, medium-sized amphibious excavators can deeply enter the river with their flexible mobility, efficiently excavate the sediment deposited for many years, restore the normal water flow capacity of the river, improve water quality, and enhance the ecological environment of the water body. Lake maintenance work also relies on them. For example, they can clean up aquatic plants and debris at the bottom of the lake and reinforce the lake embankment to ensure the safety and ecological stability around the lake. In terms of water conservancy facility construction, whether it is building small dams or dredging irrigation channels, it can show its great capabilities and complete complex excavation and earthwork handling tasks.
2. Wetland and Tidal Flat Development: Wetlands and tidal flats have complex terrains, making it difficult for ordinary equipment to access. Medium-sized amphibious excavators, however, can easily cope with such situations. In wetland resource development, they can level the land and dig ditches, laying the foundation for subsequent ecological restoration or rational development and utilization. In tidal flat areas, they can be used for site leveling and foundation excavation in the early stages of port construction, contributing to the creation of maritime transportation hubs.
3. Urban Construction and Emergency Rescue: In urban construction, when there are construction sites with water bodies, such as urban inland river regulation and landscape lake construction, medium-sized amphibious excavators can efficiently complete excavation and filling work, saving construction time and costs. In the field of emergency rescue, when flood disasters occur, it can quickly reach the affected areas, clear the debris blocking the river, open up drainage channels, relieve flood pressure, and also participate in the reinforcement of emergency dams, contributing to the protection of people’s lives and property.

II. Advantages Compared with Ordinary Dry Excavators

1. Strong Adaptability to the Working Environment: Ordinary dry excavators can only operate on solid land. Once they encounter water bodies, swamps, wetlands, and other soft ground, they are powerless. Medium-sized amphibious excavators are equipped with special floating box or floating drum walking devices, enabling them to float on the water surface and move in the silt, greatly expanding the operation range and achieving seamless connection between land and water operations.
2. High Stability in Water Operations: Through the optimized design of the hull structure and reasonable weight distribution, medium-sized amphibious excavators can maintain good stability during water operations. Even in the case of water flow fluctuations or large excavation movements, they can safely and efficiently complete tasks. In contrast, if ordinary dry excavators are forced to be used for water operations, it is not only difficult to operate but also poses a great safety risk.
3. Reduction of Auxiliary Construction Costs: In some projects that require operations around water bodies, if ordinary dry excavators are used, it may be necessary to build complex construction platforms or carry out a large amount of site pre-treatment work, which will increase construction costs and time. Medium-sized amphibious excavators can directly enter the operation area without the need to build complex facilities additionally, reducing auxiliary construction costs and improving construction efficiency.

III. Regarding Modification and Common Operation Scenarios

1. Modification Potential and Daily Applications: For customers with modification needs, medium-sized amphibious excavators have a certain modification potential. In daily family use, for example, some fish farmers with large water ponds can modify it for pond dredging and embankment trimming to maintain a good breeding environment in the pond. Small-scale farmers who have the need for irrigation channel maintenance and small-scale water conservancy facility construction can also make the amphibious excavator useful through simple modifications.
2. Applications in Municipal Engineering: The modified applications of medium-sized amphibious excavators in municipal engineering are also extensive. In the daily cleaning and maintenance of urban rivers, by modifying and equipping with professional dredging tools, it can efficiently remove garbage and sediment in the river. In the creation and maintenance of urban landscape lakes, it can complete underwater terrain shaping and lakeside landscape foundation construction. In urban flood prevention projects, it can be modified for reinforcing dams and clearing flood discharge channels to ensure the safety of the city during the flood season.

IV. In-depth Analysis of Customer Needs in Different Countries

Indonesian Customers’ Key Concerns

Indonesia has vast tropical rainforests, numerous rivers, and rich wetland resources. It has a tropical rainforest climate with heavy rainfall, and the coastal cities have crisscrossing canals and turbulent water flows. Based on such geographical and climatic conditions, when Indonesian customers search for and understand amphibious excavators, they often focus on the following aspects:

• River Cleaning and Wetland Maintenance Capabilities: The tasks of urban river cleaning and wetland environment maintenance are arduous, with a demand for nearly a hundred amphibious excavators (boat excavators) every year. Customers hope that the equipment can efficiently clean up the sediment, debris, and aquatic plants in the river, restore the smooth flow of the river and its ecological function. At the same time, when operating in wetlands, it can adapt to the soft and muddy ground and complete excavation, leveling, and other work.
