ABSTRACT:
A floating grab dredge has first and second pontoons spaced apart sufficiently to define a work space therebetween. The work space is large enough to define a barge slip therein as well as a digging well adjacent to the barge slip. A gantry mounted on the pontoons by supports spans the work space. Material handling apparatus on one of the pontoons includes a grizzly for separating waste from recoverable material. The gantry includes tracks on which a trolley shuttles among positions above the digging well, barge slip and grizzly. When a load of dredged material is brought up from the digging well it is inspected to determine if it contains recoverable material. If it does the trolley is moved above the grizzly and the load is dumped on the grizzly. If no recoverable material is in the load, it is dumped into a barge in the barge slip and digging continues.
