To use the stage electric hoist correctly, the following steps and precautions should be followed: Pre - use Preparation 1. Equipment Inspection: Check the mechanical parts of the electric hoist, such as the wire rope, hook, rope guide, etc., to see if there is any wear, breakage, deformation, etc. Check the electrical part to ensure there is no electric leakage and the grounding device is in good condition. Check whether the limit switch is sensitive and reliable to ensure that the hook can stop in time when it rises or falls to the limit position. 2. Familiarize with Operation: The operator should carefully read the operation manual, get familiar with various functions of the electric hoist and the functions of operation buttons, and understand parameters such as the rated load and working speed of the equipment. 3. Wear Equipment: The operator should wear protective equipment that meets safety standards, such as safety helmets, gloves, etc. 4. Make a Plan: According to the weight, size, and lifting position of the stage equipment, make a detailed lifting plan to determine the best lifting points, lifting height, moving route, etc.Lifting Operation 1. Hooking Operation: Hang the hook accurately on the lifting point of the object to be lifted, ensure that the hook is firm, and prevent the hook from coming off during the lifting process. For objects with irregular shapes or unstable centers of gravity, use appropriate lifting tools and ropes to bind them to ensure that the object remains balanced during the lifting process. 2. Test Lift: When lifting a heavy object for the first time, first lift the heavy object about 100mm off the ground, stop and check the braking condition of the electric hoist. After confirming that the braking is reliable and the object is stably suspended, continue lifting. 3. Smooth Lifting: Press the up button to make the heavy object rise slowly and smoothly, avoiding sudden acceleration or shaking. During the lifting process, always pay attention to the state of the heavy object and the operation of the electric hoist. 4. Prohibit Illegal Operations: Overloading for lifting is strictly prohibited. Do not pull the heavy object obliquely. Keep the hook perpendicular to the heavy object during lifting. It is prohibited to stand or pass under the heavy object during the lifting process. Do not suddenly press the reverse button to make the electric hoist run in the opposite direction. 5. Control Height and Speed: According to the space of the stage and actual needs, control the lifting height of the heavy object to avoid collision with other objects. At the same time, do not make the electric hoist run too fast, especially when approaching the target position, reduce the speed to ensure accurate positioning. Post - use Handling 1. Parking Position: After use, park the electric hoist in the designated position, raise the hook to make the wire rope in a relaxed state. 2. Cut off the Power: Turn off the power switch of the electric hoist to cut off the power and prevent misoperation.

3. Inspection and Maintenance: Conduct a simple inspection of the electric hoist, clean the dust and debris on the surface of the equipment. Regularly carry out a comprehensive maintenance of the electric hoist, including adding lubricating oil, replacing worn parts, etc., to ensure the good performance of the equipment.
