Drag Chain Suitability

Drag chain suitability indicate if connecting lines can be operated with drag chains. They have to fulfil the following conditions to be suitbale: • Minimal bending radius: 10 × diameter (D) (Example: cable diameter (D) = 3,9 mm, bending radius = min. 10 × outer diameter, so the bending radius has to be at least 39 mm) • Minimum bending radius in case of a fixed installation: 5 × D • Guaranteed bending cycles with a bending radius bigger than 10 × D: Minimum = 2 Million. • Smallest possible friction factor between chain and wire has to be ensured. • Maximum acceleration: 5 m/s² • Tolerable horizontal traverse path at 5 m/s²: 5 m • Tolerable vertical traverse path at 5 m/s²: 2 m
