Portable pneumatic conveyors unload ship's large grain cargo
When a lightering contractor needed equipment that could first transfer a large ship's grain cargo to smaller ships and then unload the grain in port, portable pneumatic conveyors did both jobs.
For about 5 years, West Side Worldwide of Cedar Rapids, Iowa, has leased ship unloaders to lightering contractors who, in turn, sell their services to ship owners. Lightering contractors arrange for ship unloading, which, in addition to securing ship unloaders, requires arranging port time, labor, and smaller ships [in cases where a larger ship will unload its cargo into smaller ships, or lighters].
