Civil Engineering Cylinders

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 extensive experience and deep understanding of all automation technologies, we help our clients make sure that these projects go into operation on time and function reliably.

Power Generation Cylinders

Generating power from dams is an important, environmentally-friendly way to produce power. A radial gate, also called a tainter gate, is commonly used in dams and other power generation machinery. The distinct large hydraulic tainter gate cylinders Van Halteren Technologies are used to open and close the gate smoothly. Because technology is constantly changing and improving, Van Halteren Technologies uses the newest cylinder measuring system to get the exact positioning of the tainter gate cylinders. These large hydraulic cylinders have a build-in mechanical locking system, ensuring that the radial gates stay closed when they need to be closed.

Bosch Rexroth has automated the gate drives in a high number of locks around the world, including the world's largest hydro-engineering projects: the Three-Gorges Dam in China, and the locks on the Panama Canal. For mega-projects such as these, Bosch Rexroth bundles resources from its worldwide production and development network under the coordination of local specialists

Moveable Bridge Cylinders

Because bridges connect places and people, facilitating transport and trade, movable bridges must fulfill special requirements: they must be reliable and durable, yet flexible. Our hydraulic systems combine high operational reliability and power density, along with compact design, fatigue strength, minimal maintenance, and excellent controllability. Like no other drive technology.
