Judging the quality of stage chain hoists

　　The most concerned issue for customers when purchasing stage chain hoists is the quality. Quality issues are related to property and personal safety during use. Below, we will briefly explain how to judge the quality of stage chain hoists.

　　Firstly, purchase from a reputable manufacturer with complete relevant qualifications and corresponding production licenses;

　　Secondly, there is no obvious noise or noise during the trial lifting of the stage chain hoist, and the internal components run smoothly without any jamming;

　　Thirdly, the quality of the steel wire rope for stage chain hoists should be considered, and high-strength steel wire ropes should be chosen as much as possible. If it is a chain type, the quality and material of the chain should be considered;

　　Fourthly, the overall appearance and attention to detail of the stage chain hoist are carefully crafted. Good products also require meticulous attention to detail, and the selection of materials can distinguish between good and bad, as well as the level of delicacy.

　　Common faults and solutions for stage chain hoists

　　Stage chain hoists can be used for lifting heavy objects, towing, and other tasks in large-scale competitions, performances, and other occasions. However, some minor malfunctions may occur during use. Below, we will analyze the symptoms, causes, and solutions of the malfunctions.

　　The common fault phenomenon is that the chain is twisted, and the cause of the fault is usually that the chain was not sorted properly when hanging. The solution is to sort it out and hang it again;

　　The second common fault phenomenon is the jumping of the bracelet, which is caused by the bracelet and sprocket not being on the same working surface when pulled. The solution is to restore the bracelet to the sprocket and work according to the requirements;

　　The third common fault phenomenon is chain jamming. The cause of the fault is the chain jamming of the bracelet or the chain jamming of the lifting chain. The solution for the chain jamming of the bracelet is to reverse pull the bracelet to check and handle it. The solution for the chain jamming of the lifting chain is to reverse pull the bracelet to remove the stuck lifting chain, or to replace it with an equivalent tonnage chain block for repair;

　　The fourth common fault phenomenon is locking failure, which is caused by self-locking failure and friction plate failure. The solution is to replace it with an equivalent tonnage chain hoist and repair it;
