Transportation Systems


The pantograph is located on the roof of the train and collects the electricity needed to power the train.
Since pantographs make direct contact with the overhead power lines in order to obtain electricity, their usage environment is always changing due to the speed of the train and external weather conditions.
As such, pantographs need to be able to maintain a constant level of quality and collect a constant level of electricity without damaging the overhead power lines. In order to achieve this, a lot of expertise goes into the mechanism and materials used to make pantographs.


  • Space savings: Designed with a compact profile in order to maximize space on the roof of rail cars for other equipment.
  • Lightweight: Reduced number of components for greater mechanical efficiency and lower weight.
  • Low noise: Various noise measures have been implemented in the base, framework and cover, allowing for low-noise operations even on high speed trains (shinkansen, etc.).
  • Snow toughness: Reduced surface area of the framework minimizes snow accumulation surface area, which reduces the weight of snow on the pantograph.
