Precautions for installation and construction of stage chain hoist

　　1、 Choose the appropriate chain hoist

　　Choose a suitable load chain hoist based on the actual needs of the stage and the weight of heavy objects. Generally speaking, the load of a chain hoist should be slightly greater than the actual weight of the heavy object that needs to be lifted to ensure safety.

　　Choose chain hoist products with reliable quality and well-known brands. The quality of the chain hoist can be evaluated by checking the product's quality certification, user reviews, and other methods.

　　2、 Check the installation environment

　　(1) Before installing the chain block, it is necessary to check the installation environment. Ensure that the installation location has sufficient strength and stability to withstand the weight of chain hoists and heavy objects.

　　Check if there are any obstacles around the installation location, such as wires, pipes, etc. Ensure that the running trajectory of the chain hoist is not affected by obstacles.

　　(2) Check if the height of the installation location is appropriate. The hook of the chain hoist should be able to easily reach the suspension point of the heavy object and not collide with other objects during the lifting process.

　　3、 Correctly install the chain hoist

　　Install according to the installation manual of the chain hoist. Ensure that the installation positions of each component are correct and the connections are firm and reliable.

　　(1) When installing the hook of the chain hoist, make sure that the opening direction of the hook is correct and it can securely hang heavy objects.

　　(2) When installing the chain of the chain hoist, it is important to ensure that the length of the chain is appropriate and that there are no issues such as chain jamming or jumping during operation.

　　4、 Conduct security checks

　　(1) After installation, it is necessary to conduct a safety check on the chain hoist. Check whether the connections of each component are firm and reliable, and whether the chain has any signs of wear, cracks, etc.

　　(2) Check if the braking device of the chain hoist is working properly. When lifting heavy objects, the braking device should be able to brake in a timely manner to prevent the object from sliding down.

　　(3) Check whether the hook of the chain hoist is deformed, cracked, or not. Ensure that the hook can securely suspend heavy objects without falling off during the lifting process.

　　5、 Precautions for use

　　(4) When using a chain hoist, it should be operated by professionals. Operators should be familiar with the use of chain hoists and safety precautions, and strictly follow the operating procedures for operation.

　　(5) When lifting heavy objects, slowly and evenly pull the hand zipper. Avoid sudden or excessive pulling of the hand zipper to prevent heavy objects from shaking or damage to the chain hoist.

　　(6) During the process of lifting heavy objects, it is important to closely monitor the operation of the chain hoist. If any abnormal situation is found, the operation should be stopped immediately and checked and repaired.

　　(7) When using a chain hoist, avoid overloading. Strictly follow the load requirements of the chain hoist for operation, and do not exceed the rated load of the chain hoist.

　　(8) When using a chain hoist, avoid pulling it diagonally. The hook of the chain hoist should be perpendicular to the center of gravity of the heavy object to avoid damage to the chain hoist or sliding of the heavy object caused by diagonal pulling.
