Easy to use
THE SOLUTION TO GO DEEPER.
DRH cable dredges are ideal for works in inaccessible places such as artificial reservoirs and mining basins.
The ability to remove even the most difficult sediments at high depth makes them particularly suitable for dredging dams, mining basins and harbors.
The DRH series cable dredges are available in different versions and can mount a wide range of DRAGFLOW hydraulic pumps. Each pump can be equipped with accessories such as side excavators or the dredging head.
They can be easily operated by a single operator thanks to advanced control tools available according to the specific needs of the application.
Easy to transport and assembly, they can reach the most remote places. Cable dredgers are also available in an electric version.
IRON ORE TAILING POND DREDGING
One of the world’s largest mining companies ordered a Dragflow Dredge DRH85/160 for an iron mine in Brazil.
The iron ore, mixed with water, is pumped from the mine to the shore through a “Mineral Duct” (mineral duct pipeline). Once the mineral arrives to the port terminal, it gets separated from the water and loaded on barges for the ocean transportation.
The tailings have a high content of Iron with specific gravity up to 4,9 kg/dm3. Only a super duty dredging pump with an oversize motor could do the job.
Dragflow supplied a DRH85/160 dredge equipped with the dredging unit: Hydraulic Pump HY85/160 plus two Hydraulic Excavators EXHY20 and high pressure Jet-Ring System.
The Hydraulic Power Pack is driven by a 200 Kw electric motor and the power cord is floating from the shore to the power pack.
The dredge can be operated in two ways: controlled by one operator working inside the control cabin or directly from the shore through a wireless joystick with no operator aboard.
