Standardized operation and use of stage chain hoists

　　1、 Preparation before operation

　　(1) Check the equipment

　　Before using the stage hoist, it must be thoroughly inspected. The inspection includes: whether the chain is worn, broken or twisted; Is the hook deformed, cracked, or loose; Whether the brake is sensitive and reliable; Whether the shell is damaged or deformed. If any problems are found, they should be immediately stopped from use and repaired or replaced.

　　(2) Determine the weight of the load

　　Before using a stage hoist, it is necessary to determine the weight of the load to be lifted or moved. Ensure that the load weight is within the rated load range of the stage chain hoist to avoid overloading. If the load weight is uncertain, a weighing device can be used for measurement.

　　(3) Choose the appropriate installation location

　　The installation position of the stage chain hoist should be chosen on a sturdy and stable structure, avoiding installation in loose, unstable or easily deformed places. At the same time, the installation location should be easy to operate and maintain, and not affect the progress of stage performances.

　　(4) Prepare necessary tools and equipment

　　Before using the stage hoist, necessary tools and equipment such as wrenches, screwdrivers, seat belts, helmets, etc. should be prepared. These tools and equipment can help workers complete tasks more safely and efficiently during the operation process.

　　2、 Standardization during the operation process

　　(1) Correctly install the chain hoist

　　Install the stage hoist correctly in the selected installation position. Ensure that the hook is securely connected to the load, the chain is wound correctly, and the brake is in the released state. During the installation process, it is necessary to strictly follow the requirements of the product manual to avoid safety accidents caused by incorrect installation.

　　(2) Slowly pull the chain

　　When operating the stage chain hoist, the chain should be slowly pulled to avoid sudden force or rapid pulling. This can reduce the impact force of the chain, extend its service life, and also avoid load shaking or instability. During the process of pulling the chain, attention should be paid to observing the rise or fall of the load to ensure smooth movement of the load.

　　(3) Control the speed of load rise and fall

　　When operating the stage hoist, the speed of the load's rise and fall should be controlled. Avoid speeds that are too fast or too slow to prevent load shaking, instability, or accidents. In the process of controlling speed, adjustments should be made based on factors such as the weight, height, and movement distance of the load to ensure safe and efficient operation.

　　(4) Pay attention to the use of brakes

　　When operating the stage chain hoist, attention should be paid to the use of the brake. When it is necessary to stop the rise or fall of the load, the brake should be used in a timely manner to fix the load in its current position. When using the brake, it should be ensured that the brake is sensitive and reliable, and can effectively fix the load. At the same time, frequent use of brakes should be avoided to prevent brake wear or damage.

　　(5) Avoid overloading during use

　　When operating the stage chain hoist, overloading should be avoided. Ensure that the load weight is within the rated load range of the stage chain hoist to avoid exceeding the rated load and causing equipment damage or safety accidents. During use, close attention should be paid to changes in the weight of the load. If necessary, weighing equipment can be used for measurement to ensure safe operation.
