In complex scenarios such as water conservancy projects, wetland development, and water rescue, traditional excavators are often restricted by terrain and water environments, making it hard to perform. The 7.5-ton amphibious excavator (referred to as “75 amphibious excavator”) has become a key device to solve construction challenges in water and wetland environments, thanks to its features of “being able to enter water, float, and strong adaptability”. This article comprehensively breaks down the modification and selection logic of this special machinery from applicable scenarios, modification cases, procurement plans to core advantages, helping you quickly grasp the practical value of such special equipment.

I. Application Scenarios and Modification Cases of 7.5 ton Amphibious

1.Applicable Construction Scenarios

Designed specifically for water and wetland environments, the 7.5 ton amphibious excavator can accurately meet various complex construction needs. Specific scenarios are as follows:

• River dredging: For silt and debris accumulation in natural or artificial rivers, it can work directly on the water surface. With extended booms and arms, it can reach the riverbed to efficiently clean up deposited silt, stones, and domestic garbage, avoiding the problem that traditional equipment cannot operate comprehensively due to riverbank restrictions.

• Fish pond renovation: After years of use, fish ponds are prone to excessive bottom silt and collapsed ridges. The 75 amphibious excavator can float and work in the pond, completing dredging, leveling the pond bottom, and repairing ridges. It also avoids fish and shrimp losses caused by draining the pond for cleaning, without affecting subsequent breeding plans.

• Water piling and demolition: In bridge construction and wharf building, pile foundation construction is needed on water. The amphibious excavator can carry piling equipment for stable operation; for abandoned water structures (such as old wharves and floating bridges), it can safely and efficiently complete demolition without the risk of sinking.

• Salvage and auxiliary transportation: Suitable for water rescue, sunken ship salvage, aquatic weed and floating garbage cleaning. Its flexible arm can accurately grab objects; in water projects, it can also assist in transporting small building materials and tools, reducing land transportation links.

• Deep-water floating operation: In deep lakes, reservoirs, and other areas, the 75 amphibious excavator can stably carry out underwater exploration and dam maintenance with the buoyancy support of main pontoons and side pontoons, unaffected by water depth.

2.Typical Modification Cases

• Doosan 75:
• Modified in 8 days, including extending the original boom and arm, and adding a main pontoon.

• Komatsu 70:
• Modified in 9 days, involving arm extension and main pontoon installation.

• Shantui 75:
• Modified in 8 days, including extending the boom and arm, customizing a small-sized main pontoon undercarriage, and adding a positioning plate.

These cases show that most common excavator brands on the market can be modified into amphibious excavators, so there is no need to worry about model compatibility.

II. Procurement and After-Sales Information of Amphibious

1.Spot Goods and Installment Policies

The factory has three models in stock,accounting for 80% of market choices.

It supports 12 or 24 installments, providing customers with flexible payment methods to reduce financial pressure.

2.After-Sales Service and Parts Replacement

• The upper part of the excavator can enjoy local maintenance and after-sales service, while the chassis is directly connected with the factory, ensuring convenient subsequent maintenance.
• The “four-piece set” of parts mentioned in the video is recommended to be replaced after 2000-3000 hours of use to ensure stable equipment performance.

III. Whole-Machine Procurement Cases and Configuration Features

1.Whole-Machine Procurement Cases

• Jiangsu customer case:
• The customer was in a hurry to start the project and needed the equipment urgently.
• After choosing RIVER’s in-stock Sany 85, the factory only took 2 days from delivery to the equipment arriving at the site, quickly responding to urgent construction needs and avoiding project delays due to equipment delays.

• African customer case:
• After the customer informed the factory of specific construction requirements, the factory designed a scheme based on their customized data,
• completed the customized production of the whole set of equipment, and finally shipped it in a container, meeting the transportation needs of cross-border procurement.

2.Core Configuration and Operational Advantages

• Main pontoon: Suitable for silt, swamps, and other construction conditions, providing stable buoyancy.
• Side pontoon: Suitable for floating construction conditions such as the Yellow River, enhancing the equipment’s adaptability in complex waters.
• Spud pile: Can resist water flow impact, keeping the amphibious excavator stable during operation.

In addition, the 7.5 ton amphibious excavator has advantages such as low threshold, cash settlement for odd jobs, fast cost recovery, good second-hand value retention, and easy transportation, with outstanding cost performance.
