Chain rigging, how to choose

 Chain rigging is made of metal chain and ring connection rigging, chain rigging are made of high quality alloy steel, it features a wear-resistant, high temperature, low ductility, the force will not stretch like. The following you simply describes how to select the chain rigging.
Chain rigging in accordance with its main form of welding and assembly of two types of single and multi-its structure just waiting. High-strength chain rigging can be divided into those levels: chain consists of 120 chain rigging, chain rigging 100 and 80 rigging and so on.
1,100-level  load chain  rigging temperatures up to 200 degrees = 100% of rated load, 200 degrees to 300 degrees = 90%, 300 degrees to 400 degrees = 75%
2,100 grade chain elongation rigging A minimum of 20%.
3,100-level chain rigging system will not be mistaken, because only chains and have the same level of accessories to each other.
4,100 level is super-type chain rigging chain rigging, compared with 80 chains, super model biggest advantage is the same diameter, the rated load is higher than 25%, which means that the same rated load , 100 whose diameter is smaller chain.
5,100-level  load chain  rigging surface has a higher hardness and better toughness. Chain links and attachments more wear.
