The grab capacity is a combinations of elements, the bulk carrier size, the kind of material, the crane design and others , In almost 30 years in this business never seen grabs more than 60m3 (60mton capacity) and there are few numbers of these in bulk grain operation because the ship hatch is not big enough to provide safe access to the open grab. In my opinion 20 or 40 m3 grabs with four wires cranes is the most common in use, there are also integrated grabs (motorized) with capacities about 20 or 25 m3.

The important thing is the kind of ships your terminal will attend and the kind of material your equipment will unload.
