floating grab dredgers type portal

 

Our floating grab dredgers type portal are suitable for middle-sized and big sand and gravel deposits.

The floating grab dredger type portal can be applied for vessels or for a continous forwarding using floating belt conveyors or by pumps and pipes.

For an operation with vessels, the grab discharge directly into the vessel. If there are contraries like clay, boulders or wood chunks, a tilting grid can be applied.

The floating grab dredger type portal consists of two parallel pontoons which are connected by a gantry. The gantry consists of 4 columns and a crane runway, on which a winch can move. At the holding and closing ropes of the winch the grab is fixed. The grab can be designed as a rope grab or as a hydraulic grab.

The movement of the grab consists of lowering the opened grab to the ground, closing the grab, hoisting the grab to the end-position close to the winch, moving the winch over the tilting grid or the vessel, opening the grab, discharging the material - either into the vessel or into a hopper - and moving the grab back to its starting position.
