This solution is ONLY possible if the loop is obtained by connecting the supporting leg of the chain to the shortening hook of a link where no other loads have been applied (Fig. 8). The loop cannot be obtained by connecting the supporting leg of the chain to the shortening hook mounted on the same link (Fig. 8a). The free chain leg on the link where the shortening hook has been used CANNOT be used to obtain any additional loops.

When loop lifting a load, the angle between the two chain legs should not exceed 60°; therefore the angle β must not exceed 30°. Please refer to the following table when using loop chains.
