Abstract

An outrigger monitoring system and methods having a graphical user interface. A sensor measures a length of an outrigger and the outrigger monitoring system determines crane fulcrum data based on the length. The system locks the user from continuing if the outriggers are not in a valid operating position. If the user overrides the outrigger monitoring system the crane fulcrum data is then logged and the operator is allowed to continue. In some embodiments the outrigger monitoring system includes a graphical user interface for calibrating the outriggers.
