Why can't ordinary electric hoists be used for stage construction

　　The construction of the stage usually uses an electric hoist, which many people are puzzled about. The same electric hoist works on almost the same principle, so using a regular electric hoist is not enough? Now let's talk about why only stage electric hoists can be used for stage construction.

　　Firstly, it should be noted that stage electric hoists belong to chain type electric hoists, also known as lifting machines, also known as inverted electric hoists or self climbing electric hoists. It is a gourd specially designed for lifting lighting racks, speaker groups, and large scenery installations in large-scale performance occasions, and is also suitable for lifting in other temporary mobile occasions.

　　Another characteristic is the material of the stage electric hoist. Its outer shell uses a special coating that can reflect the stage's light with a small probability, avoiding interference caused by spotlights, and does not produce noise during operation, ensuring that the audience is not affected by noise interference. At the same time, it adopts a black outer shell, which has a better hidden effect on the machine position.

　　These characteristics are not possessed by ordinary electric hoists, so everyone on stage needs to use this more professional stage electric hoist.

　　Several differences between stage electric hoists and regular electric hoists

　　Electric hoists are mechanical equipment that, with the support of electricity and human control, can quickly lift heavy objects to high places and lower them. Since their inception, various types of electric hoists have evolved, including wire rope electric hoists, chain electric hoists, group hanging electric hoists, stage electric hoists, etc. We will compare stage hoists with ordinary hoists to see why they must be used on stage.

　　Firstly, from the appearance, the color of the stage gourd is black, which is more suitable for its style of hiding, avoiding high places and dark places that are not easily noticed by the audience on site;

　　Secondly, there is an incremental encoder on the body of the stage hoist, which is an advanced device that other types of electric hoists do not have. Under the control of the encoder and CNC system, a controller and an operator can fully master the lifting operation of several or even dozens of hoists.

　　From a technological perspective, the stage hoist is one step higher than a regular electric hoist, so its price is relatively expensive. The above points are the main differences between stage electric hoists and ordinary electric hoists.
