The setup
is sufficient to ensure that they are always horizontal, but if any friction or
sudden movement is there then the gondola may stick or tilt. To ensure that it never
happens and that the water and boats always remain on a perfect level throughout

end there are two cogs with diameter 8 meter to which one end of each gondola
is attached.
The
Falkirk wheel is closed down for about three weeks every year for essential
maintenance routines over major components, like pumps and valves. During
shutdown, engineers thoroughly examine the wheel and inspect the structure and
make all necessary improvements. It is a definitely a wonderful place
to visit. It is something like a dream spot, everything is huge and
majestic, but not to forget, it’s all scientific.
