Why can stage hand pulled gourds be used upside down to lift heavy objects

　　The stage inverted hoist actually refers to a regular stage chain electric hoist, but because this type of electric hoist can be used upright or inverted, it has an additional name.

　　Why can only other types of electric hoists be used for upright hanging, while stage inverted hoists can be used for both upright and inverted hanging? This is mainly related to the structural construction and operating components of the stage electric hoist. Its top and bottom are respectively equipped with hooks that can be hung at fixed lifting points, and the style and structure are identical. If one of them is used to connect stage equipment, the other can be used to connect stage truss beams.

　　This design is very suitable for large-scale lifting projects, improving the lifting progress of stage equipment while reducing the cost of lifting operations.

　　When using the upper hook of the stage hoist to lift stage equipment, it is important to avoid surrounding stage equipment and the cover of the electric hoist, in order to prevent these obstacles from colliding with the equipment being lifted and causing it to fall from a height.

　　The reason for the paint peeling off on the stage chain hoist cover

　　The cover of the stage chain hoist is made of special paint, which is not easy to reflect the lights on the stage. But sometimes after using it for a period of time, we may find paint peeling off on the gourd. Why is this?

　　Legitimate stage chain hoists from big brands generally do not experience paint peeling. However, if you purchase counterfeit or inferior products, there is a possibility of paint peeling for no apparent reason;

　　However, regular stage gourds can also cause paint peeling due to various reasons, such as being hit or bumped during use, which may result in the paint on the surface of the cover being knocked off;

　　The working environment can also have an impact, as some high-temperature, highly corrosive, or humid environments may corrode the surface of the casing, leading to paint peeling;

　　In addition to these reasons, if maintenance is not carried out on time or stored in harsh environments, the speed of rusting or aging of the gourd cover will accelerate, and the surface paint may also peel off faster.

　　The spray painting of stage chain hoists not only reduces the reflection of light, but also has a certain protective effect, so we must protect the spray paint on the gourd cover to avoid paint peeling.
