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

　　In stage performances, electric hoists are important devices used to hang curtains, lights, 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 motor of the stage electric hoist malfunctions, measure the voltage at the input end of the motor to confirm if it is more than 10% lower than the rated working voltage. Check if the electrical appliances in the main control circuit are damaged, disconnected, or have poor contact. If the motor makes abnormal noises, it should be stopped immediately for inspection, which may be due to single-phase operation, bearing damage, or misalignment of the coupling shaft. Check if the motor is overloaded and if the motor bearings are damaged, which may cause excessive temperature rise in the motor.

　　When the motor of the stage electric hoist malfunctions, comprehensive analysis and handling should be carried out from multiple aspects such as checking the 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 in a timely manner to ensure that the stage electric hoist can work normally.

　　Why is the exhibition using stage electric hoists

　　The exhibition is a platform that provides business exchange, product display, and industry information sharing. It brings together exhibitors and visitors from various industries, aiming to promote trade cooperation, technological exchange, and market expansion. Exhibitions are usually held indoors and require a spacious and bright interior. Some exhibitions not only use stage electric hoists to hang lighting fixtures, but also some decorations to achieve better exhibition results.

　　Exhibitions usually have limited time, and it is necessary to quickly build and dismantle booths. The use of stage electric hoists can quickly complete the lifting and positioning of heavy equipment, such as sound systems, lighting, and other exhibition facilities, greatly improving work efficiency. The safe hanging and handling of equipment is crucial at the exhibition. The stage electric hoist has multiple safety protection functions, such as overload protection and emergency braking system, to ensure the safety of equipment lifting process. The stage electric hoist generally adopts an electric control system, which is simple and convenient to operate. The lifting of the equipment can be precisely controlled through a remote control, reducing the investment of manpower and material resources, and also reducing the difficulty of operation. Moreover, the stage electric hoist is easy to carry and operate, meeting the needs of various exhibitions.

　　During the exhibition construction process, the stage electric hoist plays an important role, not only lifting the truss, but also hanging lighting fixtures and sound systems to ensure the smooth completion of the exhibition.
