RUD D-profile chain

RUD D-profile chain, the round steel chain 2.0, is the leading technologically advanced round steel chain. Due to a larger cross-sectional area, it has a higher maximum load with

hardly changed dimensions and weights. RUD D-profile chains are case-hardened and designed for higher wear demands.

RUD D-profile chain
case-hardened version DAT

  • for motor-driven hoists.
  • for high wear loads in accordance with EN 818-7-T.
  • approx. 8% higher load capacity than comparable round steel chains!
