PRONAR trailer T683H

Trailer PRONAR T683H is a version of the trailer T683 with hydraulic side wall without a central pillar, with gives a free access to the cargo area. It is very convenient and practical solution for the transport of agricultural products on pallets. The left side wall, as unitary profiled, is lifted and bolted hydraulically (security system), which prevents the opening and loss of the carriage by unexpected leak of the system.
Trailer PRONAR T683 is an excellent solution, perfectly suited for uneven and unstable terrain.  This is achieved by using the leaf suspension of the tandem type with two single strong axles and amortized rigid drawbar. Suspension element have been selected so as to make maneuvering with the trailer easy and ensure their high stability. Permissible total weight of 20 tones is the size at which are included in the optimal way both economic aspects (price of the trailer and its low costs of ownership) and utility (optimal load capacity and cargo capacity, functionality, reliability and durability).

  1. 1
    For the transport of any type of loose materials, pallets, and feed bales.
  2. 2
    Components of walls, chassis and body of trailers are made with thicker sheet than the competitors, use of the modern coating increases the durability.
  3. 3
    In standard electrical installation, crank hand brake, supporting wedges, pneumatic brake system.
  4. 4
    Easy maneuvering the trailer by using the suspension of tandem type.
  5. 5
    Chassis frame have reliable and powerful tripartite tipping system and reinforced withstanding extreme loads drawbar with hydraulic scissor-type support.
