Trailer PRONAR T669

The monocoque PRONAR trailer T669 is intended to work under hard conditions. Tight, solid construction of the loading case enables to transport even tiny grains without any additional sealing. The grain hatch placed in the rear wall facilitates unloading and connection to the other more precise and efficient unloading equipment which is very important while transporting low density materials. Tandem suspension ensures increase pulling force thanks to additional weight placed on the rear axle. High tonnage load capacity will be well appreciated by all users.
