Hungarian value-added at the manufacturing of the French TGV

GD Was entrusted during cooperation with Latecoere (FR) to design, manufacture and to execute the site assembly of a special device for Alstom in La Rochelle plant. The special assembly device was ordered for manufacturing the newest Alstom aluminum train wagon. The design and site assembly work was done in cooperation with Latecoere, however the whole manufacturing task was completed by GD alone.

The new wagon types will be operated in inter alia the world famous TGV trains too. Thus at least GD could take part of the creation of a product representing the highest European standard.

The device is suitable to assembly the whole wagon from the pre-assembled chassis and side elements. The required length accuracy on the 23m is ±0,5 mm. The welding and grinding of the entire wagon framework is made within the device, therefore it has to withstand the increased dust load.

Side panels are attached at nearly 100 points by the hydraulically actuated positioner elements.

Roof panels are positioned accurately by hydraulic clamp cylinders.

The most complicated junctions are located at the wagon ends. To ensure the ergonomic accessibility to these points elevators are installed at both ends of the assembly device which can be elevated to the desired vertical position.

The lifting platform of the elevator can be elevated to the height so as the finished wagons can be rolled out under that.

The post-production of the wagon assembled in the device  is made at a separate workstation.
