ICE - Master link for assemblies with ICE - balancers. When using two units of 2 leg slings, where by one of which is equipped with a balancer (IWK-2S-..) and both master links are in the crane hook, the calculation of the capacity can be based on 4 bearing slings (BGR 500/DGUV Regel 100-500) provided the load is symmetrical and the inclination angle is max 45°. Hence an increment of the WLL. Chain slings, end fittings and a second ICE 2-leg sling with IAK-2S-.. have to be ordered separately.
