In Europe we need a lot of sand ,sometimes we are loosing our coastline during big storms, so we must Suck sand out of the un deep 20-45mtr sea.

Three electric driven Conveyor belts at PS , capacity 1500 m3/hr , Speed 3 mtr p/sec. One Stacker arm ,length 30 mtr , rotable over 270 degr. and luffing up to + 25 degrees ,this stacker arrangement will be used for unloading the sand in Hoppers /Trucks / Storage area on quay . For a large dredger company we developing a Spud pile lower /raising device to be used in Australia for passing by the bridges.
