This paper deals with the design of a new static rig developed by the University of Florence and Italcertifer S.p.A. The system can provide experimental calibration of different kinds of wheelsets according to the standard specifications and more severe conditions. It is the first bench where the wheelset is supported in a statically determinate way and it can rotate around its axis, allowing the optimal calibration of the measuring strain-gauge bridges.
