Twin Gantry Dredge

These systems are utilized where consistent high capacities are required.   This is basically two dredge systems on one central floatation system.  The ultimate system.  Each bucket is controlled independently.  Buckets feed either a central hopper arrangement or can be designed with two independent dewatering systems.  Redundancy is the key in these machines.  If one bucket is “down” the dredge is still able to produce material.  Another feature is the ability to dig out a stuck bucket. Sizes are typically 13 and 16 cubic yards with production from 1,000 TPH and up.
