Types and Load Limits

Chain slings boast the best resistance to abrasion, cuts, and heat in comparison to all other types of slings.  Chain slings also feature high flexibility in combination with average elongation (up to 20% prior to failure) and shock resistance characteristics.  Perhaps the most advantageous feature of a chain sling is its ability to be repaired.  Nearly all damaged components discovered during an inspection can be repaired and restored to useful conditions  Chain slings do however have the poorest strength to weight ratio in comparison to all other sling materials.

Tips on sling types

Different types of chain slings can be assembled in order to accommodate individual, specific needs. Chain slings are typically designated by a three character symbol based upon the number of legs and types of components used in the assembly




S = Single leg slingSB = Single basket

D = Double leg slingDB = Double basket

T = Triple leg slingSE = Single endless basket

Q = Quadruple leg slingDE = Double endless basket

C = Single leg sling with master link at each end

O = Oblong master link (recommended for all assemblies)

P = Pear shaped master link (upon request only)

S = Sling hook

G = Grab hook

F = Foundry hook


Tips on Working Load Limits


Sling angles have a direct and oftentimes dramatic affect on the working load limit of a sling. This angle, which is measured between a horizontal line and the sling leg or body, may apply to a single leg sling in an angled vertical or basket hitch, or a multi-legged bridle sling. Anytime pull is exerted at an angle on a leg, the tension, or stress, on each leg is increased.

It is critical that working load limits be reduced in order to account for sling angles. Angles less than 45° are not recommended and those below 30° should be avoided whenever possible. Use our load calculator or the formula and chart shown below to calculate the reduction in working load limits caused by various sling angles.

Actual sling working load limit = (Factor) x (Working load limit)
