AT FIRST
MOVING BRIDGES, LIFTING SHIPS, OPENING AND CLOSING WATER LOCK GATES:
Bosch Rexroth Engineering is up to weighty tasks. Lock barriers for coastal protection, hydroelectric power plants, or locks: for centuries, people have tried to control and use the forces of water. While the vision remains, the methods are getting better and better as technology evolves.
Bosch Rexroth has built an extensive know-how in hydro engineering solutions of any size and capacity. With our experience and deep understanding of all automation technologies, we help our client make sure that these projects go into operation on time and function reliably.

 

Ro-Ro Bridges allow loading a ferry boat with trains and other vehicles as well as the safe access of the passengers. They are equalizing the different water levels and the ferry´s draught under changing loading conditions.
Thus, when designing the hydraulic drives, especially the changing wind loads and the often very low natural frequencies of the bridge leaves have to be taken into consideration.
Movable bridges can offer these advantages even under extreme external conditions, provided that the drives operate trouble-free.
