IHC Beaver® series
The complete range of demountable IHC Beaver® dredgers, comprises several cutter models, as wheel dredgers, with delivery pipelines ranging in diameter from 400 to 750mm.
Since the introduction of the standard IHC Beaver® cutter and wheel dredgers in 1963, more than 800 units have been delivered. The design of the dredgers has been continuously updated to take advantage of the latest technological developments. Recently, this design has undergone another revolutionary update.
Reliable operation and excellent performance
The CSDs produced by IHC Beaver Dredgers are versatile tools, used all over the world in a variety of conditions.
They cover a range of dredging depths, production figures and installed power levels, and can be equipped with either cutter heads or dredging wheels. They are known for their robust construction, reliable operation and excellent performance.
IHC Beaver® dredgers are:
Their modular construction means they can be delivered fast, are easy to transport, and can be commissioned quickly at dredging sites.
One main pontoon houses the cutter ladder, ladder actuator rams or winches, control cabin, dredge pump, diesel engines, auxiliary power units, discharge line, and the spuds, including their actuator rams.
Other features include the compact dredge pump drive, which incorporates a reduction gear with integrated pump bearing and a freshwater engine cooling system, based on the well cooling principle.
Two side pontoons provide the vessel with buoyancy and storage space. They are connected to the main pontoon with a quick connection-disconnection system. All the parts are of a size which allows the dredgers to be easily transported by road, rail or sea.
Although they are highly standardised, IHC Beaver dredgers can be easily adapted to customers’ requirements, resulting in fit-for-purpose vessels with minimal delivery times and costs.
For example, the same basic design is able to carry a variety of different cutting tools, dredge pumps, and electric or hydraulic winches. It can also be adapted to work at different dredging depths.
This means several different equipment combinations are possible, and a beneficial ratio can be maintained between installed power and production levels.
Flexible in use
These dredgers are highly flexible in use, as we have demonstrated in the examples provided – these represent just a small selection of the projects we have been involved in.
