We know that group hanging electric gourds are hanging the same items together, but ordinary electric gourds are not recommended to use it like this. Because they are difficult to reach the same ascending and fall, which contains a variety of non -resistance factors, it is likely to cause a security accident

Ordinary electric gourds, even if they are the same brand, the same model, the same specifications, and the same parameters, it is difficult to achieve the real ascending and fold, because each electric gourd is controlled by one control handle and the two controllers are operated at the same time. There are always certain errors. It is difficult to make the two electric gourds achieve the same control and the same speed

The speed of the two electric gourds is different, which will cause the hanging object to be high and low, and the hanging objects can easily fall off from the low end and cause a safety accident. If the hanging objects are relatively large, it is recommended to use double -hook electric gourds for lifting, instead of controlling the same items together
