Electric gourds are mainly divided into two categories, namely steel wire rope electric gourd and ring chain electric gourd. The stage electric gourd belongs to the category of ring chain electric gourds. However, it is not used by daily hanging heavy objects, but as a more important role in stage performances. The black paint on the surface of the stage electric gourd is shiny and long -lasting. This is to adapt to the color of the stage performance. The breadth color will appear more conspicuous. At the same time, the stage electric gourd is equipped with overload protectors to prevent the hidden dangers caused by overloaded heavy objects. It is divided into two types from large categories, positive and upside down. The cost of the upside -down stage electric gourd is slightly higher, and the use is relatively lightweight.
