The daily maintenance of stage electric hoists is crucial to ensure their safe and efficient operation. Here are some daily maintenance methods:

　　1、 Pre use inspection

　　1. Appearance inspection: Check whether the shell of the electric hoist is damaged, deformed or cracked. Pay special attention to the hook, chain, wire rope and other parts to ensure that there is no obvious wear, cracks or deformation.

　　2. Electrical system inspection: Check if the power cord is intact and if the plug is loose. After turning on the power, observe whether the indicator light is on normally and whether the motor has any abnormal noise or vibration.

　　3. Control device inspection: Test the sensitivity and reliability of control buttons, remote controllers, and other control devices to ensure accurate control of the lifting, lowering, and stopping of the electric hoist.

　　4. Brake system inspection: Check whether the brake can work normally, ensure that it can brake quickly when stopping operation, and prevent heavy objects from sliding down.

　　2、 Precautions during use

　　1. Load limit: Strictly follow the load limit of the electric hoist and do not overload it for use. Before lifting heavy objects, it is necessary to accurately estimate the weight of the object and select an electric hoist of appropriate specifications.

　　2. Smooth operation: When operating the electric hoist, be steady and avoid sudden acceleration or deceleration. The lifting and lowering speed should be moderate to prevent heavy objects from shaking or colliding.

　　3. Avoid diagonal pulling: It is strictly prohibited to pull heavy objects diagonally, and the heavy objects should be lifted vertically. Diagonal pulling can increase the load on the electric hoist, which can easily lead to chain and wire rope breakage or motor damage.

　　4. Pay attention to the environment: Avoid using electric hoists in harsh environments such as humidity, high temperature, and high dust. If unavoidable, corresponding protective measures should be taken, such as using waterproof covers, strengthening ventilation, etc.

　　3、 Maintenance after use

　　1. Cleaning: After use, promptly clean the shell, chain, hook and other parts of the electric hoist to remove dust, oil and debris. You can use a clean damp cloth to wipe, and special cleaning agents can be used for stubborn stains.

　　2. Lubrication: Regularly lubricate the moving parts such as chains, wire ropes, gears, etc. of the electric hoist. Choose the appropriate lubricant and apply or add it according to the instructions in the manual.

　　3. Storage: When the electric hoist is not in use, it should be stored in a dry, ventilated place, away from direct sunlight and humid environments. Special storage racks or boxes can be used to properly store electric hoists.

　　Regular inspection: Conduct a comprehensive inspection of the electric hoist, including its appearance, electrical system, braking system, transmission system, etc. Discover problems and promptly repair or replace parts to ensure that the electric hoist is always in good working condition.

　　In short, by carrying out daily maintenance work such as pre use inspection, precautions during use, and post use maintenance, the service life of stage electric hoists can be extended, their safety and reliability can be improved, and strong guarantees can be provided for the smooth progress of stage performances.
