Draw gear spring KT-20 – 1.5 MN component

Key advantages

Draw gear springs absorb longitudinal loads and tractive forces within a train formation. They are used in locomotives, freight cars, passenger coaches and special rail vehicles. Kraftler draw gear springs comply with the requirements of EN 15566.

  • Excellent energy absorption
  • High resistance to extreme loads and physical damage
  • Reliable performance across a temperature range from -50°C to +50°C
  • Excellent resistance to harsh environments
  • Durable, sustainable and recyclable
