Beaver 425

The hull consists of three pontoons, one main pontoon housing the engine room, and two side pontoons. All parts are dimensioned to allow the IHC Beaver to be transported by road, rail or sea.

The dredger is equipped with a rapid connection-disconnection system for the pontoons, achieved using bolts at deck level, and hooks at the bottom. Further salient features of the vessel are the compact dredge pump drive incorporating a reduction gear with integrated pump bearing and a fresh water engine cooling system, based on the well cooling principle.

Various components are mounted in or on the main pontoon, including the cutter ladder, the two ladder actuator rams, control cabin, dredge pump, diesel engines and auxiliary power units, discharge line and the spuds with their actuator rams. The cutter and swing winches, mounted on the ladder, are powered by piston-type hydraulic motors.
