Pronar T683, T683H, T683P and T683U trailers

Pronar's T683, T683H, T683P and T683U trailers are excellent performers in rough and unstable terrain. This has been achieved through the use of a tandem-type spring suspension with two single strong driving axles and a suspension rigid drawbar. The permissible total weight of 20 tons takes into account both economic and utility aspects. The PRONAR T683H trailer is a version of the T683 trailer with a hydraulically raised side wall without a center post, which gives free access to the cargo area. This is a very convenient and practical solution especially when transporting agricultural crops on Euro pallets. The PRONAR T683P trailer is based on the T683 trailer chassis. The walls of this trailer are made of special durable waterproof plywood, embedded in special aluminum profiles, they were also used to embed rubber seals that ensure a high degree of tightness. The PRONAR T683U trailer is equipped with replaceable micro-rubber seals, applied to the upper frame, sides and rear making it ideal for transporting loose cargo of small granularity, such as rapeseed.
