Pronar T679/4M brand trailer

The PRONAR T679/4M trailer boasts a payload capacity of 8.5 tons thanks to its low unladen weight. The suspension used tandem suspension with longitudinal control arms with a large working range and wide tires provide great comfort and safety of work. A distinctive feature of the T679/4M stoner is the new shape of the cargo box, made of two bent sheets of metal sheets 4mm thick, and framed by a heavy-duty high-strength profile. The front wall of the box is rounded at the full height, making it possible to accurately pick out the load with a shell bucket. The trailer's trump card is its extensive optional equipment, such as a cargo box made of HARDOX steel , a tilt-and-turn hatch, extensions with a height of 800mm and many others.
