Grade 70 chains are heavy-duty chains that are also known as tender chains. They are mostly used to seal and tuck cargo on the flatbed to prevent it from falling. It is also used for towing cars, along with other flatbed trucking accessories such as grab and slip hooks that are sold separately from the chain. The mechanism of Grade 70 chains prevents the formation of rust and corrosion. They do not break easily and are efficient for all kinds of loads to be transported. Storage and care are mostly just cleaning after securing dusty or dirty cargo and keeping it in a cool, dry place.
These chains are provided at a variety of lengths depending on your requirements, and the size is customisable. The chains are sold without hooks attached to the ends so as to accommodate customisable hook attachments. Grade 70 chains are durable and light in weight compared to other high-test chains.
Hook Attachments
Since buying the chains in bulk or individually does not include hook attachments, there are hooks that are sold separately. A variety of hooks are offered, such as grab hooks, slip hooks, towing hooks, and load binders. These flatbed trucking accessories are also durable and are not affected by rust and corrosion. A detailed list of the hooks offered is below.
Grab or Clevis Grab Hooks – They are designed with a narrow throat. The reason for this is to allow a conjoining effect between two chains. The chain link is passed through the throat for non-slip handling.
Slip Hook – It has the same function as the grab hook; the only difference is that the slip hook has a wider throat.
Towing Hooks – There are several types of towing hooks that come along with the towing chains, such as long J-Hooks, short J-Hooks, cluster RTJ hooks, and mini-J hooks. The type of hook depends on the kind of vehicle to be towed.
Load Binders – Binders are also part of the flatbed trucking accessories offered, also known as chain binders. They are used to tighten the transport chain and secure cargo well. The two main types of binders are the ratchet binder and the lever binder.
Safety Considerations and Restrictions
Grade 70 chains are not permitted or allowed to lift overhead loads. This is because its mechanism does not include the alloy required for such heavy lifting. The only grades of chains allowed to do overhead lifting are grade 80, 100, and 120 chains. It is advisable not to re-galvanize grade 70 because it risks hydro embrittlement, which reduces its strength. So it should be kept chromated and stored in a cool, dry place. To verify the markings, the grade 70 stamp is usually written 70 or 7, and sometimes 700. It is also advisable to check WLL charts for the chain size.
