Values based on 6×37 IWRC EIPS wire rope. 1 Values based on 7×19 galvanized aircraft cable. 2 Actual drum capacities 25-30% less due to non-uniform winding. Wire rope tension will also affect drum capacity. Wire rope should be selected based on the breaking strength to load rating ratio and application parameters. Industry standards suggest a 5:1 breaking strength to load rating ratio for lifting and a 3:1 ratio for pulling. |
