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.

The trailer set has two parts: the front one should be towed by a prime mover or self-propelled. Rear part is like a steering dolly, should be equipped with a small diesel engine to realize manually steering.

So there are two method to transporting long beam :


Hydraulic long beam trailer	Self -propelled transporter

The axles number and trailer beam design depends on the weight of the girder.

Long beam trailer is supporting launching girder and construct bridges, it fulfills the transport job between precast concrete bridge section yard to bridge construction site.

The trailer/transporter must be strong enough to load the long beam .
