RUD D-profile chain
RUD D profile chain, the round link chain 2.0, is the leading technologically advanced round link 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 link chains!
