20–30 Ton Amphibious Excavator/Marsh Buggy
Version 1: Hardcore Professional Edition
On the frontlines of water dredging, wetland restoration, tidal flat development, and flood control, where traditional machinery struggles at the water‑land boundary, the 20–30 ton amphibious excavator breaks through operational limits with superior performance, becoming an essential asset for all‑terrain construction.
Optimized for medium‑to‑large amphibious projects, its 20–30 ton operating weight delivers an ideal balance of loading capacity and maneuverability. Powered by a high‑performance original engine, it provides strong power with efficient fuel consumption, ensuring stable performance on land and smooth operation in water. Featuring a patented pontoon undercarriage and sealed reinforced tracks, it offers an ultra‑low ground pressure of approximately 0.3 MPa, allowing it to work steadily in swamps, shallow lakes, and deep mud without sinking.
Equipped with a high‑torque hydraulic system, it delivers strong digging force and wide working range, compatible with buckets, breakers, grapples, vibratory hammers, and other attachments. It excels in river dredging, ecological restoration, tidal flat earthwork, dike reinforcement, underwater salvage, and other complex tasks. Built with high‑strength wear‑resistant steel and waterproof, anti‑corrosion components, it ensures high reliability, low failure rate, and easy maintenance even in harsh wet environments. A truly versatile solution for municipal water conservancy, environmental protection, and emergency rescue.
Version 2: Scenario‑Based Edition
Unlimited in water and capable on land, the 20–30 ton amphibious excavator is specially designed for challenging water‑land conditions.
It serves as a main force for river and lake dredging. Operating directly in shallow water without temporary platforms, it efficiently removes silt and debris, improving drainage and water quality with significantly higher efficiency than conventional machinery.
It acts as a pioneer in wetland restoration. With low ground pressure, it minimizes damage to vegetation and ecosystems while performing earth shaping, ecological cofferdams, and environmental construction.
It is a rapid responder in flood control. During flood seasons, it quickly accesses submerged and muddy areas to reinforce dikes, block breaches, and clear channels, providing critical support for emergency rescue.
Also ideal for tidal flat development, pond reconstruction, port dredging, and waterfront infrastructure, this machine combines the functions of a land excavator and a working vessel, offering exceptional cost efficiency and seamless transition between land and water.
