The 'cause' of chain disease in stage chain hoists

　　We use a stage hoist to lift the bracket and build the stage. What should we do if the low net empty hand hoist suddenly gets stuck? The correct approach is to identify the "cause" of blockchain disease and then prescribe the right medicine to solve the problem.

　　Firstly, long-term overloading of stage chain hoists can cause the chain to deform and fail to properly engage with the zipper wheel, resulting in chain jamming.

　　Secondly, the hand zipper wheel wears out, causing increased friction between the sprocket and the chain, and then the chain also wears out. Two parts with increased wear and tear do not mesh smoothly, resulting in chain jamming.

　　Thirdly, the stage chain hoist was hit, causing the sprocket to deform and the running space of the chain to decrease, resulting in chain jamming; The stage chain hoist was deformed after being hit, and when it passed through the zipper wheel, it did not match the internal slot, resulting in chain jamming.

　　Fourthly, the chain of the stage chain hoist rusted and the surface was repaired smoothly, resulting in chain jamming.

　　Fifth, the quality of stage chain hoists is poor, and gears, sprockets, and chains are prone to problems, such as chain jamming.

　　After encountering a chain problem, it is important to avoid seeking medical attention in a hurry. Professional personnel should be sought to perform the surgery (reinstalling or replacing the chain). If someone who doesn't understand the structure of stage hand pulled haws is appointed as this doctor, it may make the 'condition' even more serious.

　　Precautions for stage hoist group hanging

　　The life of a stage operator is destined to contribute to the stage industry, and lifting stage supports, lighting fixtures, and sound systems is its unshirkable responsibility. But taking the stage bracket as an example, it has a large volume and many lifting points. A stage chain hoist cannot guarantee work efficiency and safety when lifted.

　　Group hanging can not only improve work efficiency, but also complete tasks that a gourd cannot accomplish.

　　Although group cranes have many advantages, we must not take them lightly when using them, otherwise safety accidents will have serious consequences.

　　Firstly, before group hoisting, it is necessary to check the condition of each component of each hoist (whether there are cracks, wear, etc. on the hook, chain, cover, etc.). Doubling efficiency can also double the risk, and a problem with a gourd can be fatal.

　　Secondly, before group hoisting, it is necessary to ensure that the rated load of each hoist exceeds the weight of the lifted object and that the model of each hoist is consistent. Only in this way can we ensure that even if several gourds are not started at the same time, there will be no accidents of overloaded goods falling.

　　Thirdly, during the group hoisting process, try to ensure that each hoist starts at the same time as much as possible, otherwise it will cause significant damage to the hoist that starts later, and may even cause the bracket to tilt and collapse, injuring the operator.

　　In fact, by raising vigilance, maintaining a proper attitude towards homework, and keeping these three points of attention in mind and putting them into practical action, the danger of stage hand chain hoists hanging in groups can be prevented in advance.
