This work presents the design of an instrumented extensible bar for the axial loading of elevator car walls, used to certify the compliance of the car frame within the strength requirements of the EN standard 81-20:2014. A prototype of the bar was manufactured in the mechanical laboratory of the University of Bologna. The experimental validation of the system was performed in the workshop of Cabine Europa – Rebo, which is an Italian company addicted to elevator car manufacturing for worldwide commercial and luxury applications. Eventually, the performance of the loading procedure was analysed to get indications for the optimum re-design of the extension actuation system of the bar.
