4. D/d Ratio and Sheave EfficiencyThe D/d ratio represents the relationship between the diameter of the curve (D) around which the sling is bent and the diameter of the sling (d). A low D/d ratio significantly reduces the rated capacity of wire rope or slings due to localized stress. 

If a load is rigged with the crane hook offset from the Center of Gravity, the load will tilt violently until the CoG is directly underneath the hook. D/d Ratio and Sheave Efficiency The D/d ratio

If the GBP exceeds the soil’s bearing capacity, you must use timber mats or steel plates to distribute the pressure over a larger surface area. Why You Need a Rigging Calculation Spreadsheet
