The suction dredger is a type of vessel that is widely used in beach dredging projects. It utilizes a rotating cutter device installed at the front end of the suction pipe to cut and stir the riverbed sediment. Then, the excavated sediment is transported through the suction pipe with the help of a powerful pump, and is sent to the sediment storage area. Its dredging, transportation, and unloading processes can all be completed continuously at one time. It is an efficient and cost-effective dredger and is an excellent underwater excavation machine.
Product structure
Floating body: Provides buoyancy for the entire ship.
Hoe head: Grinds and disperses the sediment at the bottom and channels it to the suction pipe opening.
Engine room: Also known as the middle floating body, it installs the power system and some working systems of the entire ship and provides buoyancy.
Engine: Mostly diesel engines, providing power for the dredger and located in the engine room.
Dredging pump: Suction and discharge the materials that need to be cleared at the bottom of the water to the predetermined location. Located in the main engine compartment.
Winch of the suction dredger: The lifting winch and the lateral movement winch. The lifting winch: Controls the lifting of the bridge frame to achieve changes in the digging depth.
Lateral movement winch: The winch alternately pulls the entire ship to the left and right to achieve the lateral movement of the cutter for dredging.
Bridge frame: Ensures the digging depth and supports the cutter operation.
Positioning device: The left and right tail piles alternate rising and falling to cooperate with the lateral movement winch to swing the entire ship for work.
Operation console: The staff controls by sending signals in the form of electricity to each component to control the entire dredger.
Product features
Dredging, sand extraction, and land reclamation can be used for river dredging and dock construction. They have wide applications and good economic efficiency.
They can be completed with the cooperation of other vessels without the need for separate operations such as dredging, transporting, and unloading.
The control is convenient in the bridge, with hydraulic control and simple operation. The efficiency is high.
