The following are some precautions for the operation of stage electric hoists: 1. **Before operation**    - **Inspect the equipment**: Carefully check the appearance of the electric hoist, including whether the housing is damaged, if there are broken wires or wear on the steel wire rope, whether the hook is deformed, and if the anti - detachment device is effective. At the same time, check whether each protective device such as the limit device and the overload protection device is sensitive and reliable, and whether the grounding is good.    - **Confirm the environment**: Ensure that there are no obstacles in the stage working area, and there is sufficient space above and around to prevent collisions during the lifting process. Check whether the power supply voltage meets the equipment requirements, and whether there are safety hazards such as damaged or aged electrical circuits.    - **Familiarize with the operation panel**: Operators must be familiar with the functions and uses of each button and switch on the operation panel of the electric hoist, and know the location and usage method of the emergency stop button.    - **Make preparations**: Determine the weight, dimensions, and center - of - gravity position of the lifted object to ensure that it is within the rated lifting capacity and working range of the electric hoist. Prepare the necessary lifting tools and ensure that they are intact and suitable for the electric hoist and the lifted object. 2. **During operation**    - **Operate in a standardized manner**: Operate strictly in accordance with the operation procedures. Press the start, up, down and other buttons smoothly, avoid sudden starts and stops to prevent the object from shaking or generating excessive impact force.    - **Monitor the operation**: During the operation of the electric hoist, the operator should closely observe its operating status, including the winding of the steel wire rope, the movement track of the hook, the working sound of the motor and the braking device, etc. If there is any abnormality, stop the operation immediately.    - **Keep a safe distance**: The operator should keep a safe distance from the lifted object to prevent injury caused by the object's swinging or falling. At the same time, it is prohibited for people to stay or pass under the lifted object.    - **Pay attention to load balance**: Ensure that the object remains balanced during the lifting process, avoiding tilting or uneven loading, so as not to affect the normal operation and safety of the electric hoist. If the object is found to be unbalanced, stop lifting immediately and readjust.    - **Comply with limit regulations**: It is strictly prohibited to operate beyond the upper and lower limits of the electric hoist. When the electric hoist reaches the limit position, stop the operation immediately to prevent over - winding or over - unwinding accidents. 3. **After operation**    - **Stop the operation**: After the lifting operation is completed, press the stop button in a timely manner and cut off the power supply to ensure that the electric hoist stops running completely.    - **Reset the hook**: Raise the hook to an appropriate position to avoid potential safety hazards caused by the hook hanging in the air. At the same time, arrange the steel wire rope neatly so that it is wound neatly on the drum.    - **Clean the site**: Clean the stage working area, arrange the lifting tools and other tools neatly, remove debris and garbage, and keep the site clean.

   - **Record and report**: Record the usage of the electric hoist, including information such as the weight of the lifted object, the number of lifts, and the running time. If any problems or abnormal conditions are found during the operation, report to the superior in a timely manner and fill out an equipment failure report.
