Standards

!This product can be used for Overhead Lfting. It is strictly prohibited to use it in excess of the working load (WLL).

!Any surface coating will affect the mechanical properties of the chain.Please ask staff for details.

We follow standards:

NACM2010


Optional surface treatment: natural black, powder coating, black electrophoresis, electro-galvanizing, hot-dip galvanizing, Dacromet.


Chain lifted loads should never be transported or suspended over people.

Chain should be inspected every six months for cracks, gouges, wear, elongation, nicks, and suitability.

Chain performance can be effected by excessive temperatures or exposure to chemically active environments such as acids, corrosive liquids or fumes.

When mixing chain and components such as hooks and links, all should be rated at the work load limit of the lowest rated component or chain.


Ambient temperature during use:

Min.: -40 ℃

Max.: 200 ℃

If the application scenario exceeds or is lower than the recommended operating temperature, please consult the staff to see if it is feasible.

Q & A
What is the safety factor of Grade 80 chain?
4:1. Of course in some cases you may need 6:1 or 8:1, if you are not sure, please contact our sales staff.
What grade chain is the strongest?
The strongest chain grade at present is Grade 120. The mainstream chain grades in the market are Grade 100 and Grade 80. In general, Grade 80 chain can meet normal use.
How can I be sure your chain slings are safe?
Each chain sling we produce has a unique code. We can trace it back to the raw materials based on this code. We ensure that each chain sling is verified to 2.5 times the safe working load before leaving the factory. We ensure that each batch of chain slings is tested to 4 times the safe working load (breaking load test) before leaving the factory.
What is the difference between grade 100 and grade 80 chain slings? Which one should I choose?
Grade 100 chain slings have better performance than grade 80 chain slings. Of course, the price is definitely higher. Under the same working load, grade 100 chain slings are 25~35% lighter than grade 80 chain slings. They are also more resistant to extreme temperatures and have higher elongation.
Our chains are mostly exported to more than 30 countries
both in European and Asian markets.
