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.
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.
Mechanical systems drawing is a type of technical drawing that shows information about heating, ventilating, air conditioning and transportation around the building (Elevators or Lifts and Escalator). [1] It is a powerful tool that helps analyze complex systems.
Shadoof in Estonia. A shadoof or shaduf, [1] well pole, well sweep, sweep, [2] swape, [3] or simply a lift [4] is a tool that is used to lift water from a well or another water source onto land or into another waterway or basin.
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 ...
Schematic cross section of a pressurized caisson. In geotechnical engineering, a caisson (/ ˈ k eɪ s ən,-s ɒ n /; borrowed from French caisson 'box', from Italian cassone 'large box', an augmentative of cassa) is a watertight retaining structure [1] used, for example, to work on the foundations of a bridge pier, for the construction of a concrete dam, [2] or for the repair of ships.
3850-B power shovels for stripping, one built each in 1962 and 1964, with bucket capacities of 115 and 145 cu yd (88 and 111 m 3). 2570-W or WS, one of B-E's most popular dragline models with bucket capacities between 120 and 160 cu yd (92 and 122 m 3). Ursa Major at Black Thunder Coal Mine was reported to be the third largest dragline ever built.
The assembly drawing gives the drawing numbers of the subsequent detailed components, quantities required, construction materials and possibly 3D images that can be used to locate individual items. Although mostly consisting of pictographic representations, abbreviations and symbols are used for brevity and additional textual explanations may ...
