Precautions for installing stage electric hoist in school auditorium

　　The school auditorium is a multifunctional venue where various large-scale performances of the school are held. The installation of stage electric hoists in school auditoriums is directly related to their later use. What should be noted during the installation process.

　　Before installation, it is necessary to evaluate the load-bearing structure of the stage to ensure that it can support additional weight and dynamic loads.

　　The fixing point of the electric hoist should be selected above the stage of the auditorium, on a sturdy beam or dedicated lifting point.

　　The position of the electric hoist needs to be arranged according to the actual size of the stage and the performance requirements. It usually needs to be evenly distributed to maintain force balance and avoid unnecessary obstruction or affecting the line of sight during the performance.

　　During the installation process, it is necessary to check whether all safety devices of the electric hoist are intact, including overload protection, limit switches, and emergency braking systems, to ensure effective operation in any emergency situation.

　　After installation, it is necessary to conduct no-load and load test runs to check whether the electric hoist is lifting smoothly and the braking is reliable, ensuring accurate positioning and operation in actual use.

　　During the installation process of the school auditorium, attention should be paid to the above points. The staff should operate according to the requirements to ensure the safe completion of the installation work of the stage electric hoist.

　　How to deal with the malfunction of the stage electric hoist motor

　　In stage performances, electric hoists are important devices used to hang curtains, lighting, and other equipment to ensure smooth performance. When the motor of the electric hoist malfunctions, it is necessary to handle it in a timely manner to ensure safety and avoid affecting the performance.

　　After the malfunction of the stage electric hoist motor, measure the voltage at the input end of the motor to confirm if it is lower than 10% of the rated working voltage. Check whether the electrical appliances in the main control circuit are damaged, disconnected or have poor contact. If the motor makes abnormal noise, it should be stopped immediately for inspection, which may be due to single-phase operation, bearing damage, or misalignment of the coupling axis.

　　Check whether the motor is overloaded and whether the motor bearings are damaged, which may cause excessive temperature rise of the motor.

　　When the motor of the stage electric hoist malfunctions, comprehensive analysis and handling should be carried out from multiple aspects such as power supply, voltage, electrical appliances, motor, brake, limiter, etc.

　　After the motor of the stage electric hoist malfunctions, it is necessary to promptly handle the problem and solve it promptly to ensure that the stage electric hoist can work normally.
