The Ship Escalator
A new concept for the lockage of ships
by Marcel Hermans
The concept of the ship escalator was introduced in 1996. It provides a new alternative to existing lockage systems like conventional shiplocks, sloping planes, cascade-locks and ship elevators. The characteristics of the ship escalator make this concept very advantageous in situations with very high traffic volumes, not too much elevation difference, and no extreme variation in vessel dimensions. This concept is based on equilibrium, combining the lockage process for vessels.
