For decades, hardened and tempered RUD round steel chains have been used in manual hoists, pneumatic chain hoists and electric chain hoists. The reason: Very good wear properties and a high level of safety for the user.

Solid through and through - T version

  • For all wear loads EN 818-7-T.
  • For use in manual hoists such as spur gear pulley blocks or ratchet hoists.

For special requirements - VH version

  • For applications in manual hoists ISO 16872.
  • On request.
