In 2017, a long-standing customer and renowned manufacturer of brake systems for rail vehicles tasked us with developing and manufacturing a hydraulic test bench for various hydro brake components in trams.
In addition to the regular functional check of up to 200 different brake components in different test modes, the particular challenge lay in accommodating all the components and test processes in a test bench which was compact and mobile at the same time.
In just four months, we developed and manufactured a test bench with complex tubing and an external hydraulic supply unit. To reach the different pressure stages, a combination of internal gear pumps was used in conjunction with diaphragm accumulators and spring mechanisms. Proportional pressure reduction valves and pressure sensors guarantee reliable statements on the tightness, function, pressure stage, control function and control time – even during high test frequencies.
The hydraulic test bench is designed for use throughout Europe and can be put to flexible use in the customer’s individual locations thanks to its mobility.
