DredgeMasters International, Inc. recently delivered a new heavy-duty 16-inch portable dredge Model HPC-16LP-105 dredge to a sand and gravel mining operation. DMI designed this dredge with many cutting-edge features to meet specifications for a high-powered, efficient dredge able to accommodate an automated control and production monitoring system.The 200 ton (dry weight) dredge has a 105 foot ladder with an underwater, ladder mounted DMI HydraMaster HDM 42-18x16 dredge pump that is powered by an electronic controlled Caterpillar 3512 DITA SCAC marine auxiliary engine rated 1478 BHP @ 1200 RPM through a highly efficient mechanical drive. The dredge is capable of dredging at ladder angles of up to 60 degrees. A Caterpillar 3306 DITA engine rated 275 BHP @1800rpm provides power for the cutter drive and all winches, and for a 20 kW AC electric generator.
