System description

The newly-developed current collector is based on a conventional pole current collector. For the processes of connecting and disconnecting from the catenary, each pole has to be able to perform specific motion sequences. Therefore, existing components have been improved and new components have been added.

  • New development of trolley-heads
  • Use of sensitive controllable pneumatic actuators
  • Detection of the overhead lines by laser
  • Displacement transducers at the pneumatic cylinders for trolley-head positioning
  • Regulation of motion sequences by microcontrollers
  • In-house developed operating system (applicable to all developed control units)
  • Determination of vehicle position by GPS and other sensors
  • Truck as a test carrier
