What is the use of the storage chain bag for the stage chain electric hoist

　　Stage chain electric hoist is a mechanical equipment that uses chains to lift heavy objects such as lighting, sound, and curtains on stage. It is generally used above the stage. If the chain rusts and corrodes, it will reduce the efficiency of the hoist. Moreover, the extra chain hanging on the ground during lifting is extremely dangerous. It is necessary to use chain storage bags to manage the chain.

　　However, some people believe that it is not necessary to use a chain storage bag when the chain of the electric hoist is short, because the chain is short and will not fall to the ground, and the maintenance work is also quite simple. Adding an additional chain storage bag to the electric hoist will actually affect the lifting work.

　　In fact, using a chain storage bag has only advantages and no disadvantages. It is made of hard plastic material, lightweight, and can protect the chain from damage. When the chain stops running, it can be placed in this "small house" to be moisturized by the lubricating oil inside, avoiding corrosion caused by external moisture and impurities. It can also reduce the operator's lubrication work on the chain, which is beneficial without any harm.

　　So, customers can choose whether to purchase storage chain bags for stage chain electric hoists based on their actual operational needs.

　　Risk control measures need to be developed for operating stage electric hoists

　　Although the stage electric hoist can be manually controlled by a remote control to control its ascending and descending operation modes, there are still many unsafe factors and risks during lifting and use. The user should develop a risk control plan for it.

　　Specifically, it is mainly manifested in four aspects:

　　1. For negligible risks: no measures need to be taken and no file records need to be retained;

　　2. For permissible risks, monitoring can be used to ensure that control measures are maintained without the need for additional control measures, but improvement measures can be considered without adding additional costs;

　　3. For moderate risk: efforts must be made to reduce the risk within the specified time frame, further evaluate the occasions related to the stage and electric hoist, accurately determine the possibility of injury, and then determine whether control measures need to be improved;

　　4. In response to major risks, such as extreme weather conditions such as strong winds and heavy fog, it is necessary to wait for the risk to decrease before continuing work. When the risk involves ongoing work, emergency measures need to be taken.

　　Developing corresponding risk control measures for stage electric hoists can improve the effectiveness of stage performances and ensure their smooth progress.
