Grain elevator
Grain lifters (also pneumatic elevators ) are used in ports or train stations as a transshipment facility for loading and unloading cargo ships or freight trains with grain . The technology of using air to move grain or similar products is not new. As early as 1893, the first ship unloading of grain was carried out in England using suction pneumatics with an hourly output of 100 t.
These pneumatically convey grain and other bulk goods from the hold of a freighter or freight wagon . There are floating grain elevators that convey the goods directly on board a barge or a barge and grain elevators installed on land that convey the goods into a silo. The conveying capacities were 150 to 250 tons per hour. In addition to grain, other suitable loads such as linseed, soybeans, sunflower seeds, peanuts, copra, oil nuts and carob were also unloaded with grain lifters. In 1956 there were around 15 of these floating transshipment facilities in Hamburg.
Stationary grain elevators on railways and ports can still be found today in northern Germany and on the North American prairie .
