** Recommended working length is 80% rope capacity
NOTE: Cable Strength is the Breaking Strength. The Recommended safety factor for wire rope is; Pulling - 3.5:1 Lifting - 5.0:1
** Nominal capacity rating complies with ANSI B30.7 for Base Mounted Drum Hoists. Provides 5:1 design factor based on the rated line pull.
*Regarding ropes, ANSI B30.7 requires a minimum of 3:5:1 origin factor with 15:1 rope pitch diameter to drum diameter for most winching applications (e.g. pulling/hauling and anchor handling). For lifting and lowering a 5:1 design factor with an 18:1 rope pitch diameter to drum diameter is required.
*Recommended for extra improved plow steel IWRC wire rope.
