Based on usage, chemical composition and strength, Lifting Chains are divided into four
major classifications. This includes alloy chains, high-tensile chains or known
as transport chains, high-test chains and proof coil chains. Moreover, the
specifications consist of reach, rated capacity, grade and size.
Alloy chains
You can use these durable chains for heavy lifting.
Due to their strength, these chains are usually utilized for overhead lifting
applications. Nonetheless, some experts said that only Grade 80 or 100 alloys
are employed for this kind of application.
High-tensile
chains
According to the reports of Toolee Industrial Group, these
kinds of chains are frequently used along with high-test chains. Nevertheless,
they are different, as high-tensile chains are higher grade and thicker chains
that normally have hooks at its ends.
High-test
chains
These medium grade chains are made from medium carbon
steel and usually Grade 43. It also has a higher ratio when it comes to
strength and weight, compared with a proof coil chain. With this reason, they
are perfect for construction, logging, agricultural and industrial uses.
Proof coil
chains
These come from lower-grade lifting chains. They are
frequently utilized for applications, such as towing or logging. They can also
be used for industrial lifting, as well as farming and marine applications.
Proof coil chains are usually a Grade 30 chain, which are made from low carbon
steel. Keep in mind that this kind of chain must not be used for overhead
lifting, as they are too weak that they can break and cause damage.
