The grab-type ship unloaders are particularly designed for sea and river import ports that unload all kinds of different materials from different vessels. These unloaders have been proven themselves over decades of running and are extremely reliable.
Grab-type ship unloaders are able to handle all kinds of dry bulk material across the entire range of varying particle sizes or material properties. These dry bulk materials include coal, amongst others, iron ore, bauxite, limestone, phosphate, various fertilizers, and sulfur, etc.
