Minimum drum diameter is determined by cable diameter and bending fatigue requirements. Industry standards (ISO 4308) typically specify minimum drum-to-cable diameter ratios of 16:1 to 20:1 to prevent premature cable failure from excessive bending stress.
Groove design (parallel vs. helical) affects cable spooling efficiency and wear. Helical grooves provide better cable guidance and reduced side pressure, while parallel grooves offer higher capacity. Proper groove pitch must match cable diameter to prevent crushing and ensure even load distribution.
