How to ensure the safety of stage electric hoist construction operation

　　As an important tool for building a stage, the stage electric hoist not only requires checking the hoist itself before use, but also needs to make a series of preparations for the on-site situation while ensuring that the stage electric hoist is normal, in order to ensure stable construction. These preparations mainly start from these points.

　　① Selection of power supply voltage: Stage electric hoists require rated voltage. The magnitude of this voltage should be known in advance. The correct voltage can ensure the normal operation of the stage electric hoist, otherwise it will cause unnecessary trouble.

　　② Selection of suspension points: The selection of suspension points is a crucial step to ensure the firmness of the suspension point beams, which can withstand the weight of electric hoists and heavy objects, and ensure a good layout.

　　③ Be careful during the installation process: there are usually commanding personnel to ensure the placement of sound and lighting, as the installer cannot observe the installation location on their own. Therefore, the commanding personnel must carefully observe, promptly stop the installation deviation and make adjustments.

　　The above three points are the preparations that need to be made during the process of building a stage with an electric hoist.

　　The important component of the stage electric hoist is the motor, which is the core component. In order to extend the service life of the motor, there is a protective device on the motor, which is called a protector.

　　Traditional stage electric hoists use thermal relays as motor protectors, which have low sensitivity, stability, and poor performance, and are not very reliable in protecting the motor. Due to the increasing demand for motor strength and weight reduction, the requirements for motor protectors are also becoming higher and higher.

　　A good motor protector does not necessarily have multiple functions, nor is it particularly advanced. It should meet the needs and have high cost-effectiveness. Choose the type of stage electric hoist motor protector based on the actual situation on site, while considering the installation, adjustment, and ease of use of the protector.

　　The motor also needs regular maintenance to extend the service life of the stage electric hoist.
