Chain slings are one of the most common rigging equipment, widely used across multiple industries. They're made of lengths of high-tensile chains with various fittings attached. Reliable, flexible, and incredibly durable, rigging chains are completely customizable based on the requirement.
Finding the right chain sling and chain grade can be a tall task for the uninitiated. You need a reliable rigging chain supplier to find the best quality equipment for your project. That’s where Holloway Inc. comes in! We have a wide range of proof coil chains, alloy sling chains, transport chains, and high-test chains for you to choose from.

Chain slings are usually differentiated based on their grade. Chain grades are a standard method for determining the ultimate tensile strength of a chain and can sometimes indicate its material. Grades help establish what type of applications a rigging chain is suitable for. The most common chain grades are grades 30, 43, 70, 80, 100, and 120.
Different chain grades serve different purposes. For example, grade 30 is used for lighter applications, whereas grades 43, 70, and 80 are reserved for heavier construction jobs. Grades 100 and 120 are the most robust types of rigging chain offered by most industrial hardware suppliers and are commonly used for extremely heavy-duty applications.
Heavy-duty grade 80 alloy sling chains are certified for overhead lifting and other applications requiring tremendous strength. These rigging chains are made of an alloy-steel mixture and are strong, rugged, and built to last. Some are also available with a black lacquer finish to protect against abrasions.
Crosby Grade 80 chain slings meet the American Society of Testing and Materials' standards for overhead lifting, as they can be elongated by 15% before breaking. Grade 80 alloy sling chains are normally used for:

Follow these simple steps in making a sling assembly:
Each sling shall be marked to show: name or trademark of manufacturer, grade, nominal chain size, number of legs, rated load for the type(s) of hitch(es) used and angle upon which it is based (reach).
If measurement comes in the link, cut the following link. For two leg type slings, count the links and use an even number for clevis hooks and an odd number for eye hooks. This will position hooks in the same plane. In multileg slings always use the same number of links in each leg.
When using chain slings in choker applications, the Working Load Limit must be reduced by 20%. Crosby recommends a minimum angle of choke of 120 degrees. Consult Crosby when planning to use an angle of choke of less than 120 degrees. If Crosby A-1338 cradle grab hooks are used at a minimum angle of choke of 120 degrees, the full sling rated WLL can be utilized.
In shortening applications, a 20% reduction of the Working Load Limit is required except when using the Crosby A-1338 cradle grab hooks or S-1311N chain shortener link. They can be used without any reduction to the Working Load Limit.
The Slings shown here are standard assemblies that can be made from “Proof Tested” Crosby Components and Alloy Chain supplied by your authorized Crosby distributor. Assemblies must include chain sling identification tag.

These warnings and instructions are applicable to alloy chain slings produced from Crosby Grade 8 (80) and Grade 10 (100) chain and components.
A sling shall be removed from service if any of the following are visible on chain or attachments:
It must be recognized that certain factors in the usage of chain and attachments can be abusive and lessen the load that the chain or attachments can withstand.
Some examples are twisting of the chain; disfigurement; deterioration by straining, usage, weathering and corrosion; rapid application of load or jerking; applying excessive loads; sharp corner cutting, D/d, action and non-symmetrical loading effects.
Excessive high or low temperatures or exposure to chemically active environments such as acid or corrosive liquids or fumes can reduce the performance of the chain and components.
Chain should not be subjected to galvanizing, or any plating process. If it is suspected the chain has been exposed to chemically active environment, remove from service.
Guidelines for the interval are:
An alloy sling chain shall be removed from service if conditions such as the following are present:
