The ring has been designed in five sizes with capacities ranging from 2t (2.2 US ton) to 21t (23 US ton) based on a single-leg lift using Grade 10 chain.
The attachment is marked with the model code, the nominal diameter of chain required to maximise the working load limit of the ring and the working load limit.
The ring is art of Parsons’ Kuplex 8 + 10 chain sling system which can be used with either Grade 8 or Grade 10 chain.
