Dragflow S.r.l.

- Model DRH Series - Steel Cable Dredges


The dredge with steel cables, for being so user friendly, represents the best solution used in many touristic harbours, they find this machine as the best financial compromise between performance and initial investment. This dredge is built with technology that is suitable also for applications  where deep dredging is needed without restrictions of depth. This unit is completely modular, easy to transport and assemble. Dragflow DRH dredge has become a standard for mine tailing ponds. Its ability to work with heavy slurry, at any depth and even in presence of low pH makes this machines the 'best in class' system for tailing management operations.
