The reason for the chain jam in the hand chain hoist is here

Thread Content

The importance of chain hoists in production processes is self-evident, but their widespread use also leads to numerous problems, leaving maintenance technicians extremely busy. Users who use chain hoists for extended periods have likely encountered the problem of the chain getting stuck. When this happens, operation is halted immediately; in such cases, please adjust the device using the correct methods – forceful pulling is strictly prohibited. The occurrence and resolution of these faults not only pose a threat to users’ security but also waste a great deal of time, reducing overall work efficiency. To address this issue, Jingbo Cloud Commerce has summarized below the reasons for chain jamming in chain hoists: First, improper operation by the user causes the casing to deform, which directly affects the functioning of the internal components. Due to reasons such as the user’s daily operations or careless handling, the casing of the chain block suffers severe damage, resulting in deformation and inward compression. Therefore, when the idler wheels are affected and deformed, it directly impacts the operation of the chain, leading to issues such as chain jamming and other problems related to chain functionality ； Secondly, users fail to carry out proper maintenance of the chain hoist on a regular basis, which leads to severe rusting of the internal moving parts. If users fail to maintain chain hoists properly or follow the proper procedures, it will lead to severe rusting of the internal components, which in turn greatly affects their operational performance. When the internal components of a chain hoist are not functioning properly, it can cause problems such as gear jamming during lifting operations ； Thirdly, the user failed to inspect components such as the chain before using the chain block. Every time operations begin, the user needs to check the various components of the device as well as its overall performance. Users who fail to conduct proper inspections cannot detect abnormalities such as deformation in components like chains and sprockets in a timely manner, and using the equipment under such conditions directly leads to chain jamming.
