As for crane to be used in construction, we mention on the bridge girder erection machine. This Machine is used for erecting concrete box girders for high speed (250km,350km) passenger railway lines.
This machine is suitable for equal span girders or different span girders which can be 20m, 24m and 32m. The rear part has two supports. One of the supports is “C” shape column with rotary and foldable technology. The “C” shape column technology saved the traverse space during traveling and which enables to travel through tunnels with the girder transfer vehicle.
