Chain Sling Assemblies & Accessories

Chain slings are often selected when operating under high temperatures or rugged conditions that would abrade or destroy other types of slings. They are flexible, durable and long lasting, ductile, easy to inspect, collapsible for convenient storage, and will adhere securely to the contours of a load.

Although chain will show little or no stretch at rated capacity, it does have the ability to elongate up to 20% prior to failure. This elongation serves as a visual warning sign prompting users to remove the sling from service before personal injury or equipment damage is sustained from a broken chain sling. The most advantageous feature of a chain sling is its ability to be repaired. Nearly any damaged component discovered during an inspection can be repaired and restored to useful condition.

During the repair process, slings will be refurbished, proof tested and recertified, offering an economical alternative to new chain sling replacement.

Chain slings used for overhead lifting applications must be manufactured from alloy steel.

Alloy chain, normally 8600 series alloy, is subjected to quality control techniques surpassing those applied to lower grades of chain and is designed, approved and specifically recommended for overhead lifting.

Alloy steel chains possess the strength, chemical content and mechanical properties necessary to meet government and industry standards. These specifications prescribe minimum elongation values, minimum proof test values, recommended working load limits and minimum statistical breaking strengths.

Alloy chain can be distinguished from other popular grades of welded chain through its hallmark, or identification code, which is embossed into chain links approximately every 12” to 18”. Grade 80 (or System 8) is the most frequently used alloy chain.

Do not use any chain sling for overhead lifting before verifying that it is constructed from alloy steel by inspecting the chain prior to use.

Different types of chain slings can be fabricated and are usually designated by a three character symbol, based upon the number of legs and types of components used in the assembly as detailed below:
First Character (Basic Type of Construction)
S = Single leg sling
SB = Single basket 
D = Double leg sling 
DB = Double basket 
T = Triple leg sling 
SE = Single endless basket 
Q = Quadruple leg sling 
DE = Double endless basket 
C = Single leg sling with master link at each end

Second Character (Type of Master Link or End Link):
O = Oblong master link (recommended for all assemblies)
P = Pear shaped master link (upon request only)

Third Character (Type of Hook):
S = Sling hook
G = Grab hook 
F = Foundry hook

Safety Services Group manufactures Chain slings using permanent, welded coupling links, or if preferred, mechanical coupling links for quicker in the field assemblies. Slings have an identification tag providing the grade, size, EWL, type of sling, working load limit at a specific angle of lift, and serial number. Relative to other types of slings, chain slings have the poorest strength/weight ratio, best abrasion and cut resistance, average elongation and shock resistance, best flexibility, and best resistance to high temperatures.
