Trodat submarine pump suction dredger for sale
Hull without propulsion / optional propulsion (propulsion can be satisfied even in small size)
Self-propelled, specially designed ocean-going hull
The winch dredger needs to be fixed in position with spuds before it can start working, whether it is self-propelled or not.
The cutter head is a mechanical rotating tool that cuts hard soil or rock into pieces. The winch is pulled by pulling the winch in a fan motion, and the rotating cutter head can enter the water to swing in the soil. It is mounted in front of the suction head and delivers the chopped soil and rock directly to the mud disposal area by the powerful suction of the dredge pump.
For specific types of soil, Leader Dredger will design different cutter heads. Because different soils have different hardness and viscosity, different cutter heads will need to be used.
It is important to note that the cutter teeth need to be replaced, as dredging in hard soils can cause them to wear out.
The suction dredger equipped with a propulsion device can perform long-distance navigation and be used flexibly around the world.
Small and medium-sized suction dredgers can be disassembled and transported on land.
It should be noted that the suction dredger is very sensitive to rough seas, as rough seas can damage the positioning device of the suction dredger and cause additional damage by dislodging the winch from the water bottom. Use the three-anchor positioning method.
The spuds are required for working, and it is suitable for river surface which is still and slightly wavey, because the positioning device of the winch dredger needs to be inserted into the soil, and excessive wave surge will bend the positioning device of the dredger.
The winch suction dredger has high productivity and can handle most materials effectively.
