Roof-Mounted Pantographs

Roof-Mounted pantographs for tram lines, metropolitan railways, metros, traction units (electrical multiple units - EMUs), trains and locomotives as well as potential special-purpose vehicles are developed for various overhead line systems and speeds, whereby a raising to and lowering from the overhead line is carried out by an electric or pneumatic drive depending on customer requirements.
The continuous contact force to the overhead line at higher speeds is either realised by mechanical deflectors or by a specifically developed electric-pneumatic control system. If requested, an emergency drop is offered, which lowers the pantograph as quickly as possible in the event of collisions with the overhead line.

Local traffic

To meet the specifications and wishes of our customers, we manufacture powerful suburban rail roof-mounted pantographs according to a new, efficiency-oriented design concept - fast, well priced and low maintenance.

Special developements

To optimize the functions and to protect our roof-mounted pantographs for damage we offer several specialized components. Our open-loop-system for heavy rail vehicles ensures an uniform contact force of the pantograph on the overhead wire at all speeds. The ADD-system for light rail vehicles ensures that pantographs with damaged contact strips or collector heads are lowered automatically.
