    PRONAR RC2100-2 SECTION 1 1.5 TRANSPORT The trailer is ready for sale completely assembled and does not require packing. Packing is only required for the machine's technical documentation and any extra equipment. The trailer is delivered to the user either transported on a vehicle or, after being attached to a tractor, independently (trailer towed with a tractor).
  • Page 21 SECTION 1 PRONAR RC2100-2 movement. The number of securing elements (cables, straps, chains and stay etc.) and the force necessary for their tensioning depends on a number of things, including weight of the trailer, the construction of vehicle carrying trailer, speed of travel and other conditions. For this reason it is impossible to define the securing plan precisely.

  • Page 71: Oversize Loads

    SECTION 4 Pronar RC2100-2 When using a tractor for loading the trailer, remember to ensure that the gross weight (tractor + loaded machine) does not exceed the trailer's maximum carrying capacity. Otherwise, the ramps, drawbar or other elements of the low chassis trailer may get damaged.

  • Page 72: Ramps' Protections

    Pronar RC2100-2 SECTION 4 Unload the trailer using overhead crane, hoisting crane or another tractor. ATTENTION Lower the ramps until they fully rest on the ground. Otherwise, when a machine is driven off the load platform, the trailer will have a tendency to raise the drawbar, which may cause damage to the tractor hitch or drawbar.
  • Page 73 SECTION 4 Pronar RC2100-2 Spring catches (1) Figure (4.4) are mounted near the ramp rotation pin. Pull out the lever to position (2) in order to release the catch.
