De Olifant, Burdaard Each revolution of the screw lifts of water. The drive to the Archimedes' screw that pumps water into the polder is from a 38-cog gear wheel meshing with the "great spur wheel". This drives a 25 stave gear wheel which drives a "wallower" (30 cogs). The "wallower" drives a gear wheel with 31 cogs. This drives a cast iron gear wheel with 48 teeth. This drives the Archimedes' screw via a cast iron gear wheel with 60 cogs on the axle of the Archimedes' screw. This Archimedes' screw has an axle diameter of and is diameter overall. It is inclined
Archimedes' screw hatcheries, where it is desirable to minimize the physical handling of fish. An Archimedes screw was used in the successful 2001 stabilization of the Leaning Tower of Pisa. Small amounts of subsoil saturated by groundwater removed from far below the north side of the tower, and the weight of the tower itself corrected the lean. Archimedes screws are also used in chocolate fountains. A "screw conveyor" is an Archimedes screw contained within a tube and turned by a motor so as to deliver material from one end of the conveyor to the other. It is particularly suitable for transport of
