Hydraulically-driven grab

Hydraulically-driven grab

Hydraulically-driven grab is designed for transfer of granular cargoes of 2…2.8 t/m³ bulk density including transfer from water reservoirs bottom.

The grab consists of the upper and lower cross-pieces, the system of levers with two hydraulic cylinders, two working elements (jaws) and the autonomous submersible pump unit (with hydraulic panel) to supply hydraulic cylinders with power.
