Dredger 3000-45 project Ts490DM1 Page No. 156

Dredging unit with hydraulic and mechanical loosening. The hydraulic loosening pump is mounted on the end part and the mechanical loosener drive is mounted in the nose part of the intake frame. The ground pump with double casing of wear-resistant design is installed in the engine room.

The ground pump is driven through an elastic coupling and gearbox by a diesel engine, which is also located in the engine room on the same ship's foundation as the ground pump. The dredger is non-self-propelled and is delivered to the place of work by tugboat. The stern interpontoon flange connection is made with an eye designed for towing the dredger and pulling it to the ground.

Working movement of the dredger during mechanical loosening is carried out by pile-rope method by means of pile-lifting winches and pile-lifting winches. During hydraulic ripping, the dredger is moved by means of a bow winch, pile-lift winches and pile-lift winches via deflector blocks.
