Polymer spring KT-20 (1,5MN – 20Kj)

Unique quality advantages:

Draw gears are used to absorb the longitudinal loads and tractive forces within a train formation. They are used in locomotives, freight cars, coaches and special rail cars. Draw gear springs fully comply the requirements of EN15566 standard.

  • Excellent energy absorption
  • Incredible resistance to extreme loads and to physical damaging
  • Sustainable performance in temperatures range from -60°C to +50°C
  • Superior resistance to the most aggressive environments
  • Durable, sustainable and recyclable
