During the transportation and storage of goods, Lashing Chain, as an important fixing device, is widely used for the safe fixing and bundling of various heavy objects. It has a high load-bearing capacity and durability, but if it is not maintained during long-term use, certain failures will occur. Understanding these common failures and taking corresponding preventive measures is essential to ensure transportation safety and extend the service life of Lashing Chain.
1. Chain wear or breakage
Wear and breakage are one of the most common failures of Lashing Chain. Due to frequent use and long-term load, the surface of the chain may wear, resulting in reduced strength or even breakage. Wear usually occurs in the part that contacts the metal surface, especially the joints and locks of the chain. This damage not only affects its load-bearing capacity, but also seriously affects its safety.
Preventive measures: Regularly check the degree of wear of the chain, especially the load-bearing part. If signs of wear or breakage are found, the damaged chain should be replaced immediately. Chain materials with wear resistance and corrosion resistance, such as high-strength alloy steel, can be selected to extend the service life of the chain.
2. Rust and corrosion
Lashing Chain may rust and corrode when exposed to humid environment for a long time, especially when exposed to environmental factors such as salt water and moisture during transportation. Corrosion will cause the strength of the chain to decrease, affecting its safety and durability.
Preventive measures: To prevent the chain from rusting, you should choose a chain with anti-corrosion properties, such as galvanized or coated chains. In addition, during storage and use, avoid exposing the Lashing Chain to humid or salt water environments. If the chain must be used in these environments, it should be cleaned and coated with anti-rust oil or other preservatives after use.
3. Failure of the lock buckle
The lock buckle is a key component of the Lashing Chain, which is used to connect and fix the chain. The failure of the lock buckle is usually caused by material fatigue, rust, improper operation or long-term incorrect load use. Failed lock buckles may cause the chain to loosen, which in turn affects the safe fixation of the cargo.
Preventive measures: When using the Lashing Chain, make sure that the lock buckle meets the load requirements and check the integrity of the lock buckle regularly. If the lock buckle is found to be loose or worn, it should be replaced immediately. Use high-quality locks and ensure that they are installed correctly.
4. Uneven tension
Uneven tension distribution is a common problem during the use of Lashing Chain, especially when bundling goods. Uneven tension will cause uneven stress on the chain, which may cause some chains to be overstretched, increasing the risk of failure.
Precautions: When using Lashing Chain, ensure that the tension is evenly distributed. This can be done by using multiple chains and ensuring that each chain bears the appropriate weight, or using a tension indicator to monitor the distribution of tension.
5. Chain overstretching
Using Lashing Chain under overload conditions for a long time will cause the chain to be overstretched, causing it to lose its original elasticity and strength. Overstretched chains will not provide sufficient safety protection and may even cause breakage.
Precautions: When using Lashing Chain, the model and specification of the chain should be reasonably selected according to the weight and size of the goods to avoid overloading. If the chain shows signs of overstretching, it should be replaced in time.
