What should I do if the stage electric gourd manipulation control box does not move? Check whether the power cord of the electrical control box is connected and whether the voltage is missing. When the power supply voltage is unstable or there is a danger of short circuit, we cannot use electric gourds for operation to avoid circuit failure; when we cannot remove the actual weight of the heavy object that needs to be lifted, we cannot use gourds. Do operations to avoid the danger of overloading; when the operating environment is quite harsh, such as high temperature, rain and snow weather, or in a highly corrosive environment, this will cause damage to gourds and even operating accidents; when we cannot solidly fix it firmly When the gourd body, we cannot use it for operation.
