Maintenance of silos and warehouses
Introduction
A silo (from the Greek σιρός - siros, "pit or hole to preserve grain") is a construction made to store grain and other bulk materials. They are part of the collection stage in agriculture.
The most common are cylindrical in shape, resembling a tower. They can be made of wood, reinforced concrete or metal.
Currently, the original design for agriculture has been adapted to other uses in industry, using silos to store various materials, such as cement, and they have also been adapted to the military area, using silos to store and handle missiles.
History
The archaeological remains found and texts from the ancient world show that silos were already used in Ancient Greece, at least since the century BC. C.[1][2][3].
In Ancient Rome, large silos (pits) were built dug into the ground, plastered with clay and burned to harden it, where roasted grain was preferably stored for long-term conservation.
The first modern silo, in wood and upright and as a grain store, was invented and built in 1873 by Fred Hatch of McHenry County (Illinois) "McHenry County (Illinois)") in the USA.[4][5].

tower silos
The tower silo is a structure generally 4 to 8 m in diameter and 10 to 25 m high. Its original design is due to the American engineer Franklin Hiram King.
It can be constructed from materials such as wood beams, concrete, concrete beams, and corrugated galvanized sheet metal.
Tower silos that only hold silage are usually unloaded from the top. This task was originally done by hand with rakes "Rake (tool)"), but is now more often performed with mechanical unloaders. Loaders are sometimes used to collect from the bottom but there are problems with making repairs and with silage becoming embedded in the walls of the structure.
