Electronics, Mechatronics & Hydraulics Assembly line rollbar system


The Assembly line Rollbar system is divided in pre- and main assembly.
The pre-assembly is used for assembly and test of the drive unit. It consists of four handwork places with manual loading and automatic test.
The main assembly is also built as a handwork place with manual loading and automatic test.
Several mounting parts are assembled using a controlled screwing device. The correct assembly of the mounting part is checked with different sensors.

During the automatic test the following characteristic values are checked:

  • Resistance of the pyrotechnical device
  • Rollbar height in retracted and extended position
  • Curve while moving out the rollbar
  • Max. force while moving out the rollbar

A unique identifiable label is printed with the label printer existing in the machine.


  • Comfortable, custom-built machine interface (Windows 10)
  • Touchscreen
  • Server for type settings and analysis of the saved data/results
  • Contact-free laser-triangulation-position measuring system
  • Graphical display of characteristic curves
  • Integrated force and torque sensors
  • Data acquisition with analog input modules (16 bit A/D resolution)
