| description | The utility model relates to a crane control system capable of preventing a frequency changer from burning loss by overheating, sequentially comprising a main switch, a power switch, a controller, a frequency changer and a motor on the back end of the frequency changer along the moving direction of a power supply as well as a controller switch, wherein the controller switch is arranged between the controller and the frequency changer. As one controller switch is additionally arranged between the controller and the frequency changer, when a crane does not work or hands over the watch, as long as the controller switch is turned off, the crane control system can prevent the occurrence of a crane safety accidents caused by operating a crane mechanism under the condition that a driver know nothing because the crane driver negligently collides the crane controller in the process. As the crane control system does not need to repeatedly carry out power transmission stop to the crane main switch or the power switch, t |
