Railroad grain terminal in Hope, Minnesota. A grain elevator or grain terminal is a facility designed to stockpile or store grain. In the grain trade, the term "grain elevator" also describes a tower containing a bucket elevator or a pneumatic conveyor, which scoops up grain from a lower level and deposits it in a silo or other storage facility.
The bucket elevator is the enabling technology that permitted the construction of grain elevators. A diverter at the top of the elevator allows the grain to be sent to the chosen bin. A similar device with flat steps is occasionally used as an elevator for humans, e.g. for employees in parking garages.

[ 4 ] The building was originally equipped with three corrugated-iron nine-story-high iron legs designed to move along tracks.
Holeless hydraulic elevators were developed in the 1970s, and use a pair of above-ground cylinders, which makes it practical for environmentally or cost-sensitive buildings with two, three, or four floors. Roped hydraulic elevators use both above-ground cylinders and a rope system, allowing the elevator to travel further than the piston has to ...
