FLAT WOVEN SLINGS FLAT WOVEN SLING S When a sling experiences a reduction in Working Load Limit (WLL) due to the included angle and another reduction due to small radius bends, the two reductions are not combined. To address this, it is best to consider only the greater reduction, which corresponds to the lower WLL. For instance, let's take a 100mm wide Flat Woven Sling with a 90-degree included angle wrapped around a steel beam with a 2.0mm corner radius for a cradle lift. In this scenario: The standard WLL for this sling in a cradle lift with vertical legs is 8.7 tonnes. The WLL for this sling with a 90-degree included angle is calculated as 8.7 x 0.7071 (cosine 45) = 6.15 tonnes. The reduction due to the 0.5d radius (2.0mm) is 10%, resulting in a WLL of 8.7 x 0.9 = 7.8 tonnes. Hence, the applicable WLL in this case is the lower value, which is 6.15 tonnes.
