Remote radio control system for cranes and other mobile equipment

A receiver for controlling operations of a remote controlled machine (RCM) device having one or more motorized controls for moving at least one component associated with the RCM device, the receiver comprising:

• an antenna configured to wirelessly receive radio frequency signals;
• a power interface coupled to RCM device power;
• a processor;
• and
• a plurality of card slots, each card slot being configured to removably receive an expansion card chosen from a group of expansion cards having different types of control outputs, a plurality of the control outputs of the expansion cards connected to respective ones among the plurality of card slots being configurable depending on the type of the RCM device and the operations of the RCM device that are to be controlled;
• wherein the processor is configured to process signals received from a remote transmitter via the antenna and generate corresponding output signals to the one or more motorized controls in the RCM device via at least one of the plurality of configurable control outputs to control the one or more motorized controls in the RCM device;
• wherein the configurable control outputs are chosen from a plurality of control output types comprising a Form A relay contact output, a Form C relay contact output, a DC relay output, a latching relay output, and an analog output.
