The TG50 hydraulic diaphragm wall grab is a heavy-duty continuous wall construction flagship model engineered for the most demanding deep foundation projects . Driven by a 261 KW engine with CAT336D dedicated chassis, this machine offers exceptional hoisting force of 500 KN and maximum grab weight of 26 tons, providing superior digging capability in hard ground conditions. With trench depth capacity of 80 meters and trench width ranging from 800-1500 mm, the TG50 excels in large-scale infrastructure developments including deep basements for high-rise structures, underground transportation hubs, port and wharf foundations, and reservoir dam engineering . The TG series’ fast wall construction speed and minimal protective mud requirement make the TG50 particularly advantageous for projects in environmentally sensitive or space-constrained urban locations .
