摘要:
The invention relates to an arrangement for controlling a loading element of a crane, the loading element of the crane including an actuator and a current supply cable for supplying current to the loading element. The arrangement for controlling the loading element including a control signal generator/transmitter for generating and transmitting control signals for controlling the actuator of the loading element, a control signal receiver for receiving the control signals in the loading element and a transmission path for transmitting the control signals from the control signal generator/transmitter to the control signal receiver. The transmission path for transmitting the control signals is provided in the current supply cable of the loading element. Furthermore, the control signals may be generated by sending first the control signal and then the current supply in a time-sequential manner, interrupting the power supply for short intervals or controlling the order in which the phases of a multi-phase power supply are delivered.
