Is it unnecessary to try hanging the stage hoist before use?

　　Stage chain hoists are often used for stage construction and material lifting. Before formal use, it is recommended to conduct a trial lifting. Stage chain hoist trial lifting refers to using the stage chain hoist to lift the lifted object off the ground to 30 centimeters before formal lifting, and the lifting time should not be less than three minutes to observe whether there are any abnormalities in the stage chain hoist. Perhaps some people think it's unnecessary, is that really the case?

　　The main concern of trial lifting is the mismatch between the weight of the stage chain hoist and the lifted object. Regardless of how many tons or meters of stage chain hoist are used for lifting, it is believed that the lifted object is an estimated weight without actual weighing. The increase in weight of the lifted object directly consumes the safety factor guarantee. Therefore, the purpose of trial lifting is to check whether the bearing weight is within a reasonable range to avoid lifting accidents.

　　Before each lifting operation, it is necessary to conduct a trial lifting of the stage chain hoist. Although it may delay you by two minutes, the importance of its purpose cannot be ignored.

　　How to avoid chain breakage in stage chain hoists

　　As a light and small lifting equipment, stage chain hoists can bring a lot of convenience in some event venues, stage performances, and competition performances. They are the "little helper" for venue construction. However, things always have two sides. While bringing convenience, there may also be potential hazards, such as chain breakage, which not only greatly affects the progress of work, but also causes irreversible consequences. So how can we effectively avoid the phenomenon of broken lifting chains?

　　1. Strictly control the usage time of stage chain hoists to achieve a balance between work and rest;

　　2. Users should strictly control the lifting speed, preferably maintaining a uniform and slow speed, to prevent being unable to control the stage hoist due to the huge impact force;

　　3. When using stage chain hoists for homework, overloading is prohibited as it can cause harm to both the hoist itself and the operators;

　　4. When purchasing stage chain hoists, it is important to choose reputable manufacturers and brands to ensure quality and after-sales service, avoiding unnecessary trouble.

　　The above are specific methods to avoid the breakage of the stage chain hoist. Of course, the most important thing is to regularly inspect the stage chain hoist to nip the danger in the bud.
