Water projects often involve unstable banks, saturated soil, narrow access routes, and areas that cannot support ordinary construction equipment. The Rudra Amphimax 50EX is developed for these demanding conditions, giving operators a practical way to carry out excavation and maintenance work across marshes, canals, ponds, shallow waterways, and low-bearing-capacity ground. The machine uses a high-strength steel amphibious platform to distribute its weight and improve balance on soft surfaces. Its self-moving track system allows it to travel through marshy areas and shallow water while its hydraulic system supports digging, loading, vegetation clearance, and material-handling tasks. The 50EX model can deliver a digging depth of up to 3.70 m and a working reach of up to 7.0 m. It has a 29 kW engine, 120 L/min hydraulic flow capacity, and a buoyancy capacity of 6,500 kg. The excavator also provides a 5.2 m dumping height, making it suitable for placing removed soil, silt, vegetation, or other material into a suitable collection area.
