Working principle and operation steps of stage electric hoist

　　Stage electric hoist is a type of electric hoist commonly used in stage construction, high-altitude equipment lifting, hanging displays, and so on. The working principle of stage electric hoist is mainly based on electric motor drive and mechanical transmission mechanism. The key steps of the stage electric hoist in the working process.

　　1. When the power is turned on, the electric motor starts to rotate, and the high-speed shaft of the reducer connected through the elastic coupling also rotates accordingly.

　　2. The driving torque of the electric motor is transmitted to the last stage gear of the reducer through gears, and then connected to the hollow shaft through splines.

　　3. The hollow shaft is further connected to the drum through splines, allowing the drum to rotate under the action of torque.

　　4. As the drum rotates, the steel wire rope begins to wrap or release, thereby achieving the lifting action of the hook and the suspended object.

　　5. In order to ensure the safety of operation, stage electric hoists are usually equipped with multiple protective measures such as limit switches and dual brake systems to prevent safety risks when the chain exceeds or exceeds the weight limit.

　　6. When moving the suspended object to the designated position, the running trolley will walk along the lower edge of the I-beam, driven by an electric motor to drive the wheels on both sides of the trolley. At the same time, the electromagnetic brake on the lifting mechanism will prevent the heavy object from falling, ensuring smooth movement.

　　The above is the working principle and operating steps of the stage electric hoist

　　What is the important function of the storage bag for the stage electric hoist

　　Users who have used stage electric hoists will notice that almost every stage electric hoist is equipped with a large black storage bag. The size of this bag is basically the same as that of an electric hoist. It is not used for decoration, but plays an important role. Below is a detailed analysis of the purpose of this bag for everyone.

　　Firstly, when we use the stage electric hoist for homework, we can store the lifting chain in a storage bag. In this way, lubricating oil can effectively isolate the chain from contact with the outside world, avoiding oxidation.

　　Secondly, after ending the use of the stage electric hoist, the chain on the electric hoist can be pulled out and stored in an orderly manner in a storage bag. This can prevent friction and moisture between the chains, protecting the integrity of the chains.

　　Finally, due to the protection of the storage bag, the lifting chain of the stage electric hoist is effectively protected, which can prevent deformation and corrosion rusting caused by squeezing. Therefore, this storage bag is crucial for protecting the lifting chain of the stage electric hoist.

　　This is the main function of the storage bag for the stage electric hoist
