ROHR-IDRECO: Moving into the future with continuous innovation

ROHR-IDRECO ended last year with the successful launch of the cutter wheel suction dredger, built for Colombian gold mining specialist Mineros Aluvial – the largest they have built to date.

Many were involved in the final assembly and launching of this 53-meter long, 255-ton dredger.

Equipped with the proprietary iPump and a max digging depth of 28 meters, she has a production capacity of 270 m3/h.

According to the dredge equipment manufacturer, 2021 started with five bucket ladder dredgers for different German customers.

Two vessels are now ready for operation.

The first floating bucket ladder, for a CEMEX Group company, has a production capacity of 400 tons per hour and a digging depth of up to 15 meters.

A dewatering screen and fine sand recovery system are included, said ROHR-IDRECO.

The second bucket ladder, a KS255 designed for gravel extraction, has a capacity of 622 tons per hour.

The bucket ladder is extended in two stages: the 35-meter ladder with a conveying depth of 15 meters can be extended to approximately 47 meters, which then allows it to operate at a conveying depth of 23 meters.

The buckets are moved via a tractor chain to ensure a long lifespan.

New orders for the coming months include suction dredgers for the German and French markets and a land-based bucket ladder dredger with tractor chains for an Austrian customer.

Also, ROHR-IDRECO joined forces with SL Pumping Solutions GmbH recently.

The German company is now a dealer of the ROHR-IDRECO proprietary iPump ranging from 200 to 1100 mm suction diameter.
