The working load limit is based on static or moderately dynamic lifting/pulling operations where a load is being applied uniformly in a straight-line pull.

Best Practice: Keep your rope clean using a rope bag and wash it after every 30-40 uses. 3 along with the calculated percentage of mean breaking strength from the unknotted ropes (for fixed-fixed sample) and knotted scenarios. By shifting from steel to SK78 you gain: Easier rigging. Minimum breaking strength for rope used in two-person systems shall not be less than 9,000 lbf. The rope is secured at one end and fed over a standardized edge, while the other end is attached to a fall sled which is dropped from a height of 4.
