New Dredger for North American Sand and Gravel Operation

GT1000 Gantry Type Clamshell Dredger

Rohr-Idreco Dredge Systems has delivered new gantry type floating ‘Clamshell and Conveyor System’ to North American Sand and Gravel Operation.

This 10.5 cubic yd. (8m³) clamshell model is an electric dredger with a digging depth of approximately 200 ft (60m) and production capacity up to 500 Tph.

Rohr dredgers are designed and engineered to meet the specific requirements of each application so this dredge was outfitted with an on-board Fine Sand Recovery System, High Frequency Fine Sand Dewatering Screen Cyclone and Jaw Crusher.

The Rohr gantry type clamshell has fully automated controls (to support a one-man operation) and very low power requirements, as well as a DGPS/Sonar system for improved material recovery.

Rohr also supplied the approx. 400 ft. (240m) of floating conveyors that delivers the separated and dewatered material to the main conveyor belt system going to the plant.
