Precautions for installation of stage chain hoist

　　In stage performances, the stage hoist plays a crucial role as it can safely and efficiently lift and move various stage equipment. However, in order to ensure its normal operation and safe use, the following aspects need to be noted when installing stage chain hoists.

　　1、 Choose the appropriate installation location

　　The installation location should have sufficient strength and stability to withstand the weight of the chain hoist and the lifted objects. Usually, structures such as stage trusses and steel beams are ideal installation locations.

　　Consider the layout of the stage and the distribution of equipment, and choose a location that is easy to operate and can meet actual needs. Avoid installing in places that may affect the performance of actors or the audience's line of sight.

　　Ensure that there are no obstacles around the installation location, so that there is enough space to pull the chain and adjust the position of heavy objects when operating the chain hoist.

　　2、 Check installation tools and equipment

　　Before installation, check if the installation tools used are complete and in good condition. Tools such as wrenches, screwdrivers, and slings should meet installation requirements and be free from damage or wear.

　　Inspect the chain hoist itself to ensure that its appearance is not damaged, the chain is not deformed, and the hook is not cracked. If there are any quality issues, they should be replaced or repaired in a timely manner.

　　Check if the necessary accessories for installation, such as bolts, nuts, washers, etc., are complete and ensure that their specifications and quality meet the requirements.

　　3、 Correctly install the chain hoist

　　Follow the installation instructions of the chain hoist to ensure that the installation steps are correct and error free. Generally speaking, the first step is to fix the hook of the chain hoist in the installation position, and then thread the chain through the hook and connect it to the heavy object.

　　During installation, pay attention to the moderate tightening force of bolts and nuts. If they are too loose, it may cause the chain block to loosen or fall off, while if they are too tight, it may damage the equipment or affect its normal operation.

　　Ensure that the winding method of the chain is correct to avoid situations such as chain twisting and knotting. At the same time, it is necessary to ensure that the chain can be smoothly pulled during use without any jamming or jamming.

　　4、 Conduct security testing

　　After installation, conduct a no-load test by pulling the zipper tape to check if the operation of the chain block is smooth and if all components are working properly.

　　Conduct a load test, gradually increase the weight of the heavy object, and observe the lifting capacity and stability of the chain hoist. During the testing process, attention should be paid to safety and avoid overloading or sudden loading.

　　Check if safety devices such as limiters, brakes, etc. are effective. Ensure that these safety devices can be activated in a timely manner in case of unexpected situations, safeguarding the safety of personnel and equipment.

　　5、 Train operators

　　Provide professional training for operators who use stage chain hoists to familiarize them with the performance, operation methods, and safety precautions of chain hoists.

　　Operators should master the correct method of pulling the chain, avoiding excessive or uneven force to prevent damage to the chain hoist or affect its service life.

　　Emphasize safety awareness and require operators to strictly follow operating procedures during use, not to change or remove safety devices without authorization, to ensure the safety of stage performances.
