Excavator-Mounted Dredging Attachments
	Sludgifier is a state-of-the-art solidifier which is pinned to the excavator's boom in place of the bucket. The Sludgifier has a manifold induction system that feeds a reagent evenly over the mixer drum. The reagent solution is mixed into the material by a cutter drum with assorted knife-like teeth. The cutter drum is driven by two planetary gear drives and two axial piston motors at each end. All controls to the diesel engine and hydraulics are located in the excavator's cab. The operator has both good visibility and maneuverability.
Sludgifier attached Piranha attached
