High temperature problem of stage electric hoist

　　In general, the shell of the stage electric hoist is made of aluminum, which has good heat dissipation. However, the stage electric hoist still has the problem of high temperature and motor burnout. So what should we pay attention to in order to prevent the motor from burning out due to excessive temperature?

　　Firstly, it is emphasized that when purchasing, it is necessary to buy a stage electric hoist made of materials with good heat dissipation and equipped with a motor thermal protection device.

　　Secondly, it is recommended to purchase copper wire stage electric hoist motors. There are currently two types of stage electric hoist motors on the market: aluminum wire motors and copper wire motors. The electric hoist motor made of aluminum wire is prone to burning out or causing the machine to break down and not function properly at high temperatures. The electric hoist motor made of copper wire will not burn out at high temperatures. As long as the temperature reaches a level that the motor cannot withstand, the motor will automatically shut down. After the temperature returns to normal, it can be used normally.

　　Thirdly, when connecting the stage electric hoist, it is important to carefully monitor the power and voltage to avoid incorrect connections that may cause high temperatures.

　　Fourthly, even if the motor temperature is too high, operators should not use damp things to cool it down, otherwise accidents such as electric shock may occur.

　　Fifth, when collecting the electric hoist, be sure to pay attention. If the motor temperature is too high, please wait for the motor temperature to drop before working, otherwise sparks may be generated, which can easily cause a fire.

　　The above are some issues that should be noted when the temperature of the stage electric hoist motor is too high.

　　The principle of three prohibitions for the use of stage chain electric hoists

　　The use of stage chain electric hoists is also allowed or not allowed, and the three no allow principles for its use are:

　　Not allowed to work in the rain: one is to prevent rainwater from entering the interior of the motor and causing short circuit faults; Secondly, it is to prevent rainwater from causing certain corrosive effects on its components.

　　No two, not firmly fixed: Whether it is fixing an electric hoist or a heavy object, it must be firmly fixed, after all, the person standing under the suspended object is human. Once a heavy object falls, the consequences can be unimaginable.

　　Do not overload lifting: After all, the heavy objects lifted by the electric hoist are in a long-term suspended state. If overloaded, the impact on its components will be very serious, so special attention should be paid.

　　For the safety of operating the stage chain electric hoist, I hope you will not engage in the three prohibited operations mentioned above, okay?
