The "Iron Gate" locks

Entering the Iron Gate locks.
These are the second last and the biggest locks in the Danube.

 We entered with two commercial boats (both  double wide)

Once in the lock the gate, which came up from the bottom, is closed.
       








When the water is let out of the first chamber a gate in front of the lock drops down and we had to move into the second chamber.

 When all the boats are moved into the second chamber the gate closes behind us and we are lowered the rest of the way.

The gates are operated with huge hydraulic cylinders.
