The selection of the chain block is a key, so how should we choose a qualified chain block? You can learn about the characteristics of low-quality chain hoists, and then take precautions. Now, Guanhang will take you to learn about the common characteristics of low-quality chain hoists

① The inferior quality of the hand gourd can be judged by observation and touch. The saturation of the paint surface, the smoothness of the chain, and whether there are pits, graininess and rough touch when touching.

② Whether the rated load can reach the standard is also the key to the problem. The virtual marking of the rated load of the chain block will bring great potential safety hazards to the lifting operation.

③ There is a problem in the selection of materials for the chain. For example, the chain should be made of stainless steel, but it is mixed with other metals. This is an obvious jerry built and cheating behavior.

These three points are the common problems of low-quality chain hoists. For this, Guanhang kindly reminds you to pay attention to the selection of chain hoists to avoid potential safety hazards caused by low-quality products.
