Precautions for using stage electric hoist

　　In the wonderful presentation of stage performances, stage electric hoists play an important role. However, in order to ensure safe and efficient use of stage electric hoists, the following are some things that must be noted.

　　1、 Installation and Inspection

　　Installation should be carried out by professionals, strictly following the product manual and relevant safety regulations. Ensure that the installation position is firm and reliable, capable of withstanding the weight of the electric hoist and the lifted object.

　　Before use, carefully inspect all components of the electric hoist, including the hook, chain, motor, controller, etc. Ensure that there is no damage, deformation, or looseness.

　　Check if the power connection is correct and if there is a risk of damage or short circuit to the wires. Ensure good grounding to prevent electric shock accidents.

　　2、 Load limit

　　Strictly comply with the rated load limit of the electric hoist and do not overload it for use. Overloading may cause damage to the electric hoist, chain breakage, and even lead to safety accidents.

　　Before lifting a heavy object, it is necessary to accurately estimate its weight and ensure that it does not exceed the rated load of the electric hoist. If the weight of the heavy object is uncertain, a weighing device can be used for measurement.

　　3、 Operating standards

　　Operators should receive professional training and be familiar with the operation methods and safety precautions of electric hoists.

　　During the operation, one should maintain focus and not be distracted or engage in other activities unrelated to the operation.

　　Start and stop the electric hoist in the correct order. When starting, the electric hoist should be run without load first to check if its operation is normal, and then gradually load heavy objects. When stopping, the heavy object should be lowered to a safe position before turning off the power.

　　Control the speed of lifting and lowering to avoid being too fast or too slow. Excessive speed may cause heavy objects to shake, increasing safety risks; Slow speed may affect work efficiency.

　　4、 Security protection

　　When using an electric hoist, necessary safety measures such as warning lines, guardrails, etc. should be set up to prevent unrelated personnel from entering the dangerous area.

　　Operators should wear appropriate personal protective equipment, such as safety helmets, safety shoes, gloves, etc.

　　Regularly inspect safety devices such as limit switches, overload protection devices, etc. to ensure their proper functioning. If a safety device malfunction is found, it should be immediately stopped from use and repaired or replaced.

　　5、 Maintenance and upkeep

　　Regularly maintain the electric hoist, including cleaning, lubrication, and checking for component wear. Maintain the electric hoist according to the requirements of the product manual to ensure that it is always in good operating condition.

　　If there is a malfunction or abnormal situation with the electric hoist, it should be immediately stopped and repaired by professional personnel. Do not disassemble or repair the electric hoist without authorization to avoid causing greater damage or safety accidents.
