Precautions for the operation of stage electric hoist

　　1、 Pre use inspection

　　(1) Appearance inspection

　　Before using the stage electric hoist, it is necessary to conduct a visual inspection first. Check if the shell is damaged, deformed, or cracked, if the hook is cracked, deformed, or worn, and if the chain is twisted, tangled, or worn. If any problems are found, they should be immediately stopped from use and repaired or replaced.

　　(2) Electrical inspection

　　Check if the electrical system of the electric hoist is functioning properly. Including whether the power cord is intact, whether the plug is loose, whether the switch is sensitive, etc. At the same time, it is necessary to check whether the motor is running normally and whether there are any abnormal noises or heating phenomena. If any problems are found in the electrical system, professional personnel should be immediately sought for repair.

　　(3) Load inspection

　　According to the rated load of the stage electric hoist, check whether the items to be lifted or moved exceed their load capacity. If the rated load is exceeded, the use should be stopped immediately and suitable lifting equipment should be selected.

　　2、 Operational standards during operation

　　(1) Operator requirements

　　The operators of stage electric hoists must undergo professional training, familiarize themselves with their operating methods and safety precautions. Operators should remain focused during the operation process and are not allowed to leave their workstations without authorization. At the same time, operators should wear necessary personal protective equipment, such as safety helmets, seat belts, etc.

　　(2) Lifting and lowering operations

　　When lifting and lowering items, operate slowly to avoid sudden start or stop. At the same time, pay attention to observing the rise and fall of items to ensure their smooth operation. When approaching the target position, slow down slowly to avoid collision between the object and the target position.

　　(3) Mobile operation

　　When moving the stage electric hoist, ensure that its walking path is unobstructed and there are no obstacles. Meanwhile, it is important to observe the movement of the electric hoist to ensure its smooth operation. During the movement, overloading or overspeeding is not allowed.

　　(4) Emergency situation handling

　　If there is an emergency situation during operation, such as a malfunction of the electric hoist or falling objects, the operation should be stopped immediately and corresponding emergency measures should be taken. Such as pressing the emergency stop button, notifying relevant personnel for handling, etc.

　　3、 Maintenance and upkeep after operation

　　(1) Cleaning and inspection

　　After using the stage electric hoist, it should be cleaned and inspected in a timely manner. Remove dust and dirt from the outer shell, and check for damage or wear on components such as hooks and chains. If any problems are found, they should be repaired or replaced in a timely manner.

　　(2) Lubrication and maintenance

　　Regularly lubricate and maintain the stage electric hoist to extend its service life. According to the instructions, lubricate the various components of the electric hoist, such as chains, gears, etc. At the same time, it is necessary to maintain the motor, check whether its insulation performance is good, and whether the electric brush needs to be replaced.

　　(3) Storage and Preservation

　　When not using the stage electric hoist, it should be stored in a dry, ventilated, and safe place. Avoid being affected by environmental factors such as direct sunlight, rain, or humidity. At the same time, the hook, chain and other components of the electric hoist should be retracted to avoid damage.
