Before using any product, it is important to note that we need to understand how to maintain the product. For example, the chain hoist, which is frequently and widely used, inevitably causes some problems. So where are we willing to go? After being disassembled and reassembled by professionals, the hand chain hoist can only be used normally. So, what should be paid attention to when disassembling and reassembling the hand chain hoist? Below is your introduction.

　　After disassembly and reassembly, the hand chain hoist cannot be immediately put back into use for lifting work. During this period, there are two important tasks that should be carried out according to the provisions of JB/T 7334 for dynamic load performance testing and braking performance testing of the hand chain hoist. After disassembly and reassembly, the hand chain hoist can only continue to be used normally after meeting the requirements.
