This purpose-built sling is designed for extremely short lengths, enabling single-point lifts beneath Ramshorn Hooks on large cranes. It allows centreline loading on the crane’s lower block, minimising risk of skewing or damage to the hook assembly and wire rope caused by off-centre loads.

Description
Features
This sling is basically a Double Ended Superflex Strop, middled as in a cradle lift. Each eye of the middled strop is then attached to one hook of the ramshorn (see drawing). In the bight (middle) is a fitted heavy duty open type cast steel thimble to provide a good radius and minimise wear and tear on the cables. It is retained in the assembly with two Keeper Plates. These thimbles will accommodate the industrial Master Links as used in general rigging practice, thus providing a single lifting point exactly under the centreline of the ramshorn or double hook.
Designed originally for the heavy duty work of Andromedas’ Recovery Strops and made of 1000 MPa cast steel, these thimbles far exceed the Breaking Strength of the Superflex cables fitted in them. Andromeda has carried out extensive break tests on these cast thimbles and found them to be suitable for this application.
