Project Description

Working Context description

The new DRAGFLOW Amphibious Dredgewas sold by our Dragflow Chilean distributor Jacol to an important mining company in the North of Chile. The machine is workinginmultiple tailings ponds of an oldiodine mine in the Atacama Desert.

 

The projectwas very challenging since in addition to the usual purpose to pump back for reprocessing the old tailings discharged in these ponds for decades, the client requested to have a single equipment capable to move itself among the ponds where the high depth of the water doesn't allow the use of the "standard" amphibious excavator.

Since the water level in the ponds isextremely variable the costumer decided to purchase an Amphibious Dredge in order to easily workon every kind of conditions, even when the water level is minimum.

 

 

Our solution

The DRM85/160E22 is equipped withtwo lateral tracked floaters that allow this new machine to move on the ground like standard earth moving machine. On the other hand, the additional central floater gives to the amphibious the necessary buoyance allowing it to float on the water surface with the stability of standard DRAGFLOW dredges.

Furthermore, the machine can work in halfway conditions like muddy and soft soils, shallow waters and swamps.

 

The new DRAGFLOW Amphibious Dredge is not just an excavator machine able to work also in the water. It is a perfect floating dredge suitable for working on any type of soil.

The extreme mobility in any kind of wetland and the full buoyancy, allow the Amphibious to reach the most remote location otherwise impossible to get with any other dredging equipment.

 

The machine is equipped with:

- Diesel engine (260 kW) running the hydraulic power pack

- Dredging unit composed by DRAGFLOW pump HY85/160 plus two cutters EXHY20

- Jet Ring System with high-pressure water jets helping the pump in the driest dredging conditions
