Pronar brand trailers T679/3, T679/4

In order to better tailor its trailer offer to the needs of its customers, PRONAR has introduced two new types, the T679/3 and T679/4 models. Seemingly, the T679/3 and T679/4 trailers are similar to the T679/2, but feature a different design tailored to transport different materials that exert more pressure on the walls and floor. These trailers have walls and floor made of steel with increased hardness. They are equipped with a tandem suspension with a rigid longitudinal control arm with a wide range of operation in rough terrain.
