PRC-2 type trailers are mainly intended for carrying farm products, in particular loose farm materials, such as grain and corn. The bottom Fuhrmann profile, used in them, affect the board resilience and adherence accuracy. Additionally, the products are distinguished by the applied sealing technology. The trailer has a tandem type suspension structure with two centrally located axles. The loading case structure allows to open the board from each side with a central lock. The used innovative system of seven locks ensures non-deforming and ideal holding. The 3-side tripper of the loading case allows to conveniently and efficiently unload the trailer. Moreover, an additional discharge window is located in the rear board, allowing for stream unloading. The trailer can be equipped with a tarpaulin. Standard products have new tires.
