In various engineering construction and operation scenarios, amphibious excavators play an important role with their unique performance and wide applicability. Amphibious excavators are multi-purpose equipment suitable for land, swamp soft ground and shallow water operation environments. Its special feature is its unique walking device, which usually adopts a multi-hull pontoon structure and a sealed box-shaped track shoe, which can safely walk and operate in silt and water.
This excavator has obvious advantages. First, it can operate in some places that are difficult for ordinary excavators to reach, such as coastal areas, lakes, silt swamps, shallow water areas, etc., such as underwater canal opening, river cleaning, fish pond dredging, etc. Secondly, its advanced hydraulic system and power system devices are scientifically and reasonably matched, which can easily realize compound operation actions and ensure the unity of high efficiency and high economy of work. The spacious driving space and concise light, sound and audio-visual warning system also improve the convenience and comfort of operation.
However, amphibious excavators also have some limitations. For example, its walking ability on land is relatively weak, and most of the time it needs bucket assistance. Moreover, although it can operate on water, it has strict requirements on the water depth. When the water depth exceeds a certain range, the excavator will float on the water and cannot work. If the operation is not careful, it may cause the vehicle body to tilt or overturn. In addition, due to its special working environment, once a fault occurs, it will be more challenging to handle than a dry land excavator. Therefore, it is necessary to do a good job of maintenance on a regular basis, such as paying attention to checking the fuel tank to prevent the fuel tank from burning out during work; when operating, be careful not to dig into the moving iron shell chain rail to avoid damage to the hull.
In actual applications, amphibious excavators are widely used in water conservancy projects, dredging of rivers and lakes in urban and rural construction, resource development and environmental remediation excavation operations of wetlands, swamps and tidal flats, as well as port construction, urban construction and other fields. It has played a key role in some key projects, such as dredging of Meixi Lake in Changsha, water management of Dongting Lake, dredging of the 2,000-ton waterway of Xiangjiang River in Zhuzhou, and dredging of the Daqing Oilfield River.
For second-hand dealers, amphibious excavators are also a potential market. They play an important role in this. Second-hand dealers can acquire various types of amphibious excavators and conduct a comprehensive inspection and evaluation of their performance and condition. The inspection includes key components such as crawlers, pontoons, cabs, engine compartments, hydraulic systems, etc. to ensure the reliable performance of the equipment.
Second-hand dealers can also provide appropriate equipment selection suggestions based on the specific needs and working conditions of customers. They understand the characteristics of amphibious excavators of different models and configurations, and can help customers find the machine that best meets their engineering needs. At the same time, dealers will also provide customers with detailed information about the equipment, such as usage history, maintenance records, etc., so that customers can clearly understand the true condition of the equipment. And in order to increase the attractiveness of the equipment, some second-hand dealers may also provide relevant after-sales services, such as a certain period of quality assurance, equipment maintenance support, and spare parts supply. This can make customers who buy second-hand amphibious excavators more assured and reduce worries. When choosing a second-hand amphibious excavator, customers also need to consider carefully. In addition to paying attention to the price of the equipment, it is also necessary to pay attention to its quality and performance. The actual condition of the equipment can be fully understood through field visits and test drives. In addition, it is also important to understand the credibility and reputation of second-hand dealers. Choosing reliable dealers can reduce the risk of purchase.
In short, amphibious excavators have an irreplaceable position in specific fields due to their unique design and performance. The participation of second-hand dealers provides the market with more choices and possibilities, but also requires buyers to fully understand and consider when choosing to ensure that they obtain cost-effective and in-demand equipment, so as to play its greatest role in various engineering operations.
