Each radio system operates under all operations with its own unique identity code (ID-code). This means that only the correct portable control unit can activate and control its matching receiver (crane). For maximum safety the receiver has double processors to enable comparison and checking of the data signals from the control unit. The receiver on the crane operates with a so called automatic emergency stop, which means that the dump valve and all crane movements are only activated as long as verified data signals are received from the control unit. The receiver also operates with so called automatic dumping of the oil flow, i.e. the oil is dumped directly to the tank and makes the whole crane without hydraulic pressure if no lever activations have been made. The pump flow is returned as soon as a lever is activated.
