ABSTRACT:
A control arrangement for a loading device for bulk goods containers is proposed. The movement cycle of the loading device is controlled by an electronic control device. The control device has an input which is connected to several electric control signal transmitters which at a certain position of the loading device generate a signal. The output of the control device is connected to electric control members which switch on the drive of the loading device for different movement steps thereof. This is achieved by the control device through switching from one control member to another control member when the respective control signal transmitter generates a signal that the movement step of the loading device has occurred in a correct manner. In order to prevent any faulty controls, which occur when the control signal transmitters are not working properly, an arrest circuit is provided which prevents that the control signal transmitter transmits signals to the control device in an incorrect sequence. Consequently, undesired or even dangerous movement steps of the loading device are prevented.
