A large application direction of the lifting chain is the application of the gourd chain. The crane chain of the handbuishe and the electric gourd is used to use the lifting chain. The gourd chain's requirements for the width of the inner width are not high. Some of the inner width can also be used on the gourd chain, but the requirements for the inner width are relatively high, and the inner width should be used to use it, otherwise the butterfly buckle will be stuck. This is just for some low -priced hands to stretch gourds, high -quality gourds still need to use the inner width standard lifting chain. In addition, there are only three specifications of chains on the generalist on the handle gourd, namely: 6mm 8mm and 10mm. For some new types of gourds, it will also use 7.1mm 9mm 11.2mm here. Therefore, the output of the three specifications of 6 8 10 10 specifications is very large, because there are many places to apply these three specifications.
