The overload protection device of electric gourds is a "self -protection system" for overloading for electric gourds. Checking relevant information can be seen that overload protection devices are generally installed in "high -end" electric gourds. The reason why it is installed in high -end electric gourds is because it is a new skill itself, and it is a high -tech modern product. With it, it will increase the grade of the entire electric gourd. The same electric gourd and the same specifications of the same specifications, there will be some differences in adding overload protection and non -additional prices. The overload protection device of electric gourds is a special protection device for manipulators, gourds and loads. When the load is greater than the setting value, the overload protection is automatically enabled, and the rising gourd will stop automatically. This avoids a series of safety accidents caused by overload. At present, 50%of the safety accident of electric gourds is caused by improper operation, and the other 50%of them are caused by overloading. Overloading will cause the electric gourd steel wire rope or chain to break, resulting in a decrease in heavy objects and causing safety accidents. The overload protection device will start the device immediately when the overload is used to cut off the power, and the safety is extremely high.
