COAL BERTH SYSTEM (5/7) Grab Crane- Travelling overhead trolley grab crane : 500~4,000 tph- revolving grab crane : 200~700 tph Generally, the unloading of conventional bulk carriers takes place by two shore-based grabbing crane per berth, with effective unloading capacities per berth in the range of 1050 to 1750tph. These cranes discharge the load into hoppers fixed on the cranes, which feed a conveyor belt system. Loading System type () SENest , .Travelling TypeLiner TypeRadial Type3. () SENest , .1.
