Scientists at the Technical University of Munich (TUM) (Germany) have developed a new test rig for concrete bridge girders. Six double-acting hydraulic cylinders, which provide a constantly increasing massive pressure, apply said pressure with full force until the structure of the concrete bridge girders breaks. Essentially, the alternating activation of the double-acting cylinders allows the concrete element to be stressed both for bending and transverse force, as well as for torsion - i.e. for twisting. In this way, the load-bearing capacity of the bridge girders can be determined. Since 2017, the Technical University of Munich has been successfully testing the pre-stressed bridge girders with the help of our hydraulic cylinders. An analysis of the realistic load-bearing behaviour of the girders is possible on the basis of the collected data.

Our flexible hydraulic cylinders supported Burde Engineering GmbH in the modification of a 90t excavator of its customer, Plannerer Gmbh. The former is not only a provider of innovative tools and assemblies, but is also a project planner and system engineer. In the mutual project, the said excavator was converted into a longfront demolition machine with several equipment variations. Among other things, we provided it with our boom and stick cylinders as attachment cylinder.
