Product Description
Introduction Chain Slings
Alloy steel chain and components for use in mechanically assembled chain slings in accordance with BS EN 818-2&4.
Chain slings are used primarily for overhead lifting and are generally used in conjunction with a crane or some type of lifting device. Standard sling configurations consist of chain branches, which are affixed on one end to a master link or ring, with some type of attachment, usually a hook, affixed to the opposite end.
Our Grade 80 chain slings are recommended for use in a industrial environments where flexibility, strength, resistance and long life are required.
Alloy 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 injury or damage is sustained from a broken chain sling. Perhaps 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 replacements.
Chain slings used for overhead lifting applications must be manufactured from alloy steel. Alloy chain, commonly CrMnMo 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 1M to 3M. Grade 80 (or System 8) is the most frequently used alloy chain and carries a hallmark "G80" or "T8" hallmark for easy identification.
Do not use any chain sling for overhead lifting before verifying that it is constructed of alloy steel. 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:
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
Chain Slings-- Overhead lifting chain slings are useful tools for various types of overhead lifting operations and are frequently used for material handling in construction and manufacturing
