GRADE 100 CHAIN SLING COMPONENTS

Grab Hooks

Grab Hooks, the most popular and versatile hooks, are designed with a narrow throat and used to shorten or hold a chain used.

There are several types of grab hooks:

• Clevis Hooks are the most popular style of fittings because they do not need a connecting hook. Made to be attached directly to a length of chain.
• Eye Grab Hooks need a connecting link to attach to the chain or another sling type, such as a wire rope sling. They are often used as chain shorteners on a chain sling.
• Cradle Grab Hooks, refer to grab hooks that have a casted design in the middle so the chain can lay on it. This cradle design allows for 100% efficiency, meaning no loss in the working load limit.

Sling Hooks

Sling Hooks have a wider throat design than grab hooks and come with a latch that offer more security and safety. Sling Hooks are available both as Clevis Type hooks and Eye Hook. They are widely used on chain slings and wire rope slings.

Many heavy haulers now use grade 100 chains for their heavy equipment loads and machinery (such as excavators) moves. Chain slings with Sling hooks and Foundry hooks are preferred due to their large throat opening that can hook onto a wide range of attachments. The strength of grade 100 is ideal for securing heavy haul loads.

Foundry Hooks

Foundry Hooks, are similar to sling hooks but offer a wide deep throat opening. Foundry hooks come without a latch and are available in clevis or eye type.

Self Locking Hooks

Self Locking Hooks, have an advantage over latched hooks. They have a locking mechanism that once closed needs to be manually opened. These are heavy duty robust hooks that are often used on chain slings, wire rope slings and winch lines.

There are several types of self locking hooks:
Clevis Self Locking Hook which allows direct attachment to the chain sling.
Eye Type Self Locking Hook which needs a connecting link for attachment, and can be used on other sling type, not just chain.
Swivel Self Locking Hook which allows the hook to ‘swivel’ turn and line up before the load is applied. It cannot be swiveled under load.

Connecting Links

Connecting links are made out of 2 pieces that are connected by a load bearing link. Also known as couplers or hammerlocks, they are used to connect two components together.

On chain slings they are commonly used to connect the the chain legs to the master link. They can also be used to connect synthetic slings, shackles, bolts, and other components together. They are easy to assemble and disassemble and are widely used.
