The Railway carriage axis control system consists of mobile equipment including four independent hydraulic cylinders (or actuators), that are capable of lifting a railway carriage up to 150 mm from the zero plane that is defined from time to time by the expert operator. The control system makes it possible to carry out weight, track twist and tilting tests, with the feature of being mobile in order to allow its online use on flush mounted tracks.
The tests are carried out by lifting the carriage to a pre-established height and then by moving the actuators in accordance with a user-defined profile (space-time). While the test is being carried out, the force (through pressure) and shift values are recorded.
Each cylinder has a maximum load capacity of 200 kN, with the possibility of managing a maximum tilt value of 7° through the ball joint on the piston head.
