During use, the chains will wear and break, and their life will be reduced. Therefore, they need to be replaced. When replacing, the replacement time is long, and repair and maintenance will affect the mining progress. In order not to delay the overall mining, it is necessary to quickly replace the transmission belt and connect it.
