floating grab dredgers type gantry

 

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

The floating grab dredger type gantry consists of a gantry which is mounted on a closed pontoon-system. The gantry consists of a fixed and a hinged column as well as the 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 grab works inside a dredging hole of the pontoon-system.

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, opening the grab, discharging the material into the hopper and moving the grab back to its starting position over the dredging hole.
