5 . About 18 Inch Hydraulic Cutter Suction Dredger
1. Replaceable teeth
The cutter teeth are fixed on the cutter head by bolt connection.
Therefore, depending on the material to be dredged, they can be
easily interchanged between three different types, or replaced when
worn.
2. Tilting pile
The dredger has pegs that can be manually tilted and fixed to the
deck. This design ensures the easy storage and movement of the
dredger, and facilitates road transportation on water and on
flatbed trucks.
3. Hydraulic propulsion
The hydraulic thruster of the cutter suction LD3700 is installed on
the back of the pontoon. This makes it easy to maneuver around
sparse areas without supporting boats and other expenses.
6. Hydraulic System: German Brand Hydraulic Parts:
To drive: 1 cutter header, 1 ladder winch, 2 side winches,2 spud
rams, 2 hydraulic pumps, and a lot of hydraulic valves The extra
emergency pump can drive all hydraulic parts using the extra
emergency generator set.
