What is a cutter suction dredger?

A cutter suction dredger is a type of dredging vessel that is equipped with a rotating cutter head and a suction pipe. The rotating cutter head is used to loosen the sediment at the bottom of the body of water.

How Does a Cutter Suction Dredger Work??

Cutter suction dredgers work by using a rotating cutter head to loosen sediment at the bottom of a body of water. The cutter head is typically a circular wheel with a series of sharp teeth that rotate as the dredger moves forward.

What is the main purpose of dredging?

The main purpose of dredging is to deepen and maintain navigational channels, which allow ships and boats to reach their destinations more safely and efficiently. There are several dredging systems and types.

What is marina and harbor dredging, and why is it necessary?

Marinas and harbors are essential transportation centers for boats and ships that require regular maintenance to operate correctly. The accumulation of sediment, silt, and other debris in these waterways can cause shallow waters that impede navigation and pose safety risks to vessels.

An image of a hydraulic rotating cutter head used as a component of a cutter suction dredger. It features sharp teeth or cutting edges that are specially designed for specific types of sediment, such as clay or hard rock, to improve its performance and efficiency. The cutter head is mounted on the front part of the dredger and rotates at high speed to effectively cut and shred material such as soil, rock, and other sediment, making it easier for the dredger to pump the material out of the water. The dredge cutter head is powered by a hydraulic motor and is capable of digging into the material and breaking it up. With its ability to efficiently break up and cut through material, the hydraulic rotating cutter head is an essential tool for dredging operations. — Cutter head dredger front part

Dredge Cutter Head Front Part

A hydraulic rotating cutter head is a component of a cutter suction dredger that is used to break up and cut through material, such as soil, rock, and other sediment, that needs to be excavated or removed from the bottom of a body of water. It is typically mounted on the front part of the dredger and rotates at high speed to effectively cut and shred the material into smaller pieces. The dredge cutter head is powered by a hydraulic motor, and it is capable of digging into the material and breaking it up, which makes it easier for the dredger to pump the material out of the water. Some rotating cutter heads also have teeth or cutting edges that are specially designed for specific types of sediment, such as clay or hard rock, to improve their performance and efficiency.

We manufacture complete cutter ladders units for various types of cutter suction dredgers. Each unit comes with a dredge cutter head (complete with hydraulic motor) and a ladder construction. The cuttershaft also includes the necessary underwater bearings. The cuttershaft is capable of handling a power of up to 1000 kW.
