Designed standard: DIN5685,EN818-2,GB/T20652,GB/T12718,GB/T20946
The general usage grade of chain is S(6),T (8)
The ratio between usage load and breaking load is 1:4
There are single-leg , double-leg ,multi-leg , ring chains and other structure chains.
The characteristics of the chain :Wear-resistant, anti-high temperature, corrosion-resistance, low elongation
lifting chain
Material :high-quality alloy steel ( 20Mn2、20MnV、25MnV and imports of alloy steel ) ;
Manufacturing standards in line with the standard JB/T8108.1-1999 of lifting short chain;
Strength grade ： M(4) 、S(6) 、T(8);
Security assurances: four-fold safety factor, 2.5 proof load.

Care and use of chain
1: Must be used in the range of its rated loading
2:chain in a distorted 、 reversed and entangled state are not permitted to use.
3:Objects must hang on the central of the hook , the edge of the hook shall not be hung in . The heavy objects should not be hung in hook for a long time .
4:If one of the following things appears , chain slings should be stopped using immediately
A: Diameter damaged 10% of the original
B: Chain appears cracks , bending , distorting or surface damage ( phenomenon )
C: chain’s permanent elongation exceed 5% of the original length .
