WebOct 14, 2013 · Dynamic climbing rope has an elasticity of about 45 percent (or more) at failure, but it also has a slight reduction in breaking strength compared to the same size three-strand or multi-plait rope. In the May 2012 issue of Practical Sailor, we demonstrated how wind loads on a six-ton catamaran anchored in 16 feet of water with a 3/8-inch, all … WebThis means NEVER use the rope where the load applied is greater than the working load determined by dividing the Minimum Breaking Strength of the rope by the appropriate Design Factor. NEVER ‘SHOCK LOAD’ a wire rope. A sudden application of force or load can cause both visible external damage (e.g. birdcaging) and internal damage.
WebWorking Load Limit will not apply in these circumstances because a shock load is generally significantly greater than the static load. Inspect wire rope regularly. Use inspection … WebAn industry term usually computed by dividing the catalog Breaking Strength by the catalog Working Load Limit and generally expressed as a ratio. For example: 5 to 1. Shock Load. A load resulting from rapid change of movement, such as impacting, jerking or swinging of a static load. Sudden release of tension is another form of shock loading.
