    • Imperforabile
    • Acid, oil, solvent proof
    • Trace proof
    • Thermal resistance from + 180°C a - 45°C.
  • Traction effort lower than 100 N/t: a top performance in its field.
  • Trolley structure wholly made of welded pressed sheet-steel and box-worked steel; this guarantees the best structural strength and allows the necessary elasticity.
  • Steering is made of tubular, pressed steel plate, and it rotates on large grinded hardened steel bearing running on continuous pre-lubricated balls.
  • The front axle is cushioned by a patented rubber bearing; this system eliminates frame torsion and permit oscillations and anti shock effect.
