MAURER supplies expansion joints, bearings, and dampers for bridge and viaduct projects. One of MAURER’s global projects in this area is the Çayırhan Bridge project in Ankara.
One of the key features of this project is that the area where the bridge is located is constantly subject to flooding. Therefore, the main function of the bearings designed for the bridge is to be flood resistant. When designing the SIP bearings — Sliding Isolation Pendulums, the risks of floods, earthquakes, and high structural loads were also considered.
The key tasks related to the bearings designed for that project were protecting the bearings from dust and other factors, keeping them serviceable, ensuring resistance to loads of up to 10,000 tons, and providing seismic mobility by mitigating horizontal forces.

The tasks performed by the Çayırhan Bridge bearings were:
- Transmitting vertical loads up to 56 MN.
- Ensuring horizontal displacement up to 157 mm.
- Distributing seismic forces through bearing sliding.
- Returning the structure to its standard position after an earthquake using the sliding bearing.
