Excavator arm and hydraulic pump for dredging

Before turning to Dragflow, dredging took place with an excavator with long extendable arm, placed on a barge. But the operations were proceeding too slowly: more effectiveness was needed. We therefore proposed the Dragflow HY85/160 HC hydraulic pump equipped with a DTM85 cutter head, connected to the arm of a CAT345. This proved to be the winning choice for customer needs.

The Dragflow dredging unit has guaranteed a daily production of about 280 m³ of solid material (working 10-11 hours a day), with the unloading at 1 km distance from the barge. The possibility of mounting the hydraulic pump on the excavator arm made it possible to take advantage of the equipment already present on site, greatly increasing the efficiency and speed of the work. In four months 25,000 cubic meters of dry sand were dredged: proof that the HY85/160 HC pump with a dredging head was truly the ideal tool for this job!
