Liebherr-Transportation Systems was recently selected by Tangshan Railway Vehicle Co. Ltd. (Tangshan, China) to supply anti-buckling systems for low-floor trams.

Anti-Buckling System by Liebherr-Transportation Systems

The hydraulic anti-buckling system assures that the specified clearance profile is maintained under all operating conditions which may be encountered. As this function is classified as being safety-critical, the system is also monitored by an electronic circuit (known as the BK3 controller) integrated by Liebherr. The Liebherr anti-buckling system improves ride comfort and reduces wear on the wheels, as the carriage bogies are connected by a shared hydraulic coupling.

A prototype vehicle has already been equipped with the buckling protection system. Between now and the end of the year, this will undergo trials. After that, series production of the systems for low-floor trams will start in Tangshan. In the future, these trams are also to be employed in other medium-size and larger cities in China.
