Product Detailed
Bridge girder erection machine trait 1.Easy to installation and fix 2.Sales very hot 3.Widely used in highway and railway

Bridge girder erection machine trait

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. 

(1) Main feature:

integrate erecting and transporting bridge girder togetherunique honeycomb-girder structure, low deflection and high stiffnessput boundary beam in place one time when it has a side load. Without outrigger hanging in the air, quite reliablegirder-erecting error is ≤5mm with inching girderunique pin connection, easy installation ,quite safe and firmcontinuous girder with A-type section, low gravity center, convenient and safe, no additional weight is added when the machine crosses one pier to another pier
