The Saint-Louis-Arzviller inclined plane boat lift
FRANCE

Prior to the construction of the incline, barges needed 8 to 13 hours to traverse the 17 locks and 10,200 cubic metres of water was needed to operate the series of locks. The incline can be traversed in 4 minutes and requires only 40 cubic metres of water. Because the design uses counterweights to balance the weight of the caisson being moved, the entire operation can be run by two 120 horsepower electric motors, which causes a surprisingly small energy consumption.
