Heavy Duty Amphibious Excavator | Rudra Amphimax 250EX

The Rudra Amphimax 250EX is engineered for excavation and dredging operations where conventional excavators face difficult access conditions. Designed around the 21-25 ton excavator class, it uses high-flotation pontoons and amphibious tracks to work across marshes, waterlogged ground, soft soil, and shallow aquatic environments.

With a 9.4 m maximum digging depth, reinforced long-reach boom and arm, and multi-attachment capability, the Amphimax 250EX supports demanding excavation, dredging, weed removal, and coastal protection operations. Its marine-grade construction and corrosion protection are designed for extended operation in wet environments.
