Chain Sling Connections and Hitches

Connection to FittingsConnection to Fittings

  • Use master links to collect slings and to connect to hook.
  • Use Grade 8 (80) or Grade 10 (100) fittings that match the WLL of chain and offer proper securement.

Choker CapacityChoker Capacity

A choker hitch has 80% of the capacity of a single leg sling only if the angle of choke is 120 degrees or greater. Choke angles less than 120 degrees will result in a significantly reduced capacity.

No loss in capacity results if a cradle grab hook is used.

Basket Hitch CapacityBasket Hitch Capacity

A true basket hitch has twice the capacity of a single leg only if the legs are vertical. Note that the basket is formed by using a chain sling with two masterlinks at each end connected to the hook.

Horizontal Capacity % of Angle Single Leg
90 200%
60 170%
45 140%
30 100%

Multiple Leg Slings

Triple leg chain slings have 50% more capacity than double leg chain slings (at same sling angle) only if the center of gravity is in center of connection points and legs are adjusted properly (they must have an equal share of the load). Quad (4 leg) chain slings offer improved stability, but do not provide increased capacity. The capacity of a four leg chain sling is considered the same as three leg chain sling.
