Girder trailer ---We also call it Long beam trailer.

Normally the long girder length is about 20-60meters .The weight is about 30tons-400tons .There are box shape girder and T shape girder.We can design different kinds supports for loading different shape girders.

Long beam trailer is a kind of trailer sets for transporting long cargoes by loading two ends of them.It is the most effective and economical way for transporting over long cargo and abornormal shape cargo like girder,long steel structure, long steel pipe, precast concrete beam and long bridge sections.
