Pronar brand trailers T900, T902

PRONAR T900 trailers are designed as a unique solution among large dump trailers and are characterized by the use of a sliding wall unloading system. The PRONAR sliding-wall trailer series includes two models differing in allowable tare weight of 35 T in T900 and 24 T in T902, as well as in the type of running gear used. The chassis frame design is based on heavy-duty rectangular hollow sections made of high-strength structural steel, which ensures its high rigidity and durability. The chassis system used, with a single multiple axle of the tandem or tridem type with the active steering system used, provides the trailers with excellent maneuverability and, thanks to the pressure on the drawbar eye of 3000 kg, the transport capacity of the trailer and the towing capacity of the tractor are improved.
