How to increase the service life of lifting chains

　　How to increase the service life of lifting chains? The lifting chain has a scrap standard, and it is not only replaced when it breaks. It mainly depends on whether the surface of the chain is damaged, worn, and whether the chain is cracked, deformed, and so on.

　　We can reduce the occurrence of such situations during use. The chain material is a type of alloy steel, and rust can cause surface wear on the chain. The chain comes into contact with air, which has humidity. The higher the humidity, the more severe the oxidation and rusting of the chain. Therefore, when storing or using the chain, try to avoid a humid environment.

　　If the chain is used as a transmission or load-bearing chain and needs to pass through the sprocket, check the chain and do not twist it when using it. If the chain is twisted, not only will the sprocket get stuck, but the chain will also wear out.

　　When using a chain, choose the specifications according to the instructions. It should be noted that the vertical load capacity and angled load capacity of the same specification chain are different. The angle will reduce the load-bearing capacity of the chain, and the larger the angle, the smaller the load-bearing capacity.

　　Do not overload, as it is not only unsafe but also accelerates chain deformation and cracking. Chains also need maintenance, which can be checked regularly, and suitable rust proof oil can be selected according to needs to lubricate and maintain the chains.

　　Summary: To increase the service life of the chain, it is necessary to use it correctly, avoid overloading, conduct regular inspections, and maintain it.

　　Quenching treatment of lifting chain

　　Quenching can improve the hardness, strength, and wear resistance of chains, while tempering can enhance the toughness of chains. The 80 level lifting chain has undergone quenching and tempering treatment, with high surface hardness and good toughness.

　　Depending on the diameter of the chain, some slight adjustments are needed for the quenching and tempering temperatures. Quenching requires selecting the appropriate temperature based on the material and the size of the workpiece, and tempering is the same.

　　Operational errors may result in the chain not meeting the required strength and toughness. The chain may become unusable due to its high brittleness.
