An outrigger pad monitoring system for determining crane stability includes a plurality of outriggers having sensors for measuring a load placed on the outriggers. A crane control system utilizes the measured load on the outriggers to determine the stability of the crane. A crane control system utilizes the measured load on the outriggers with positional information for the crane boom to determine if the crane boom is in a side-load condition. The outrigger pad monitoring system may be used during the setup of the crane and to verify the proper operation of a rated capacity limiter. 1. A crane having an outrigger pad monitoring system , the crane comprising:a) a crane body; i) an outrigger body coupled to the crane body;', 'ii) an outrigger jack coupled to the outrigger body and configured to selectively extend and retract relative to the outrigger body;', 'iii) an outrigger pad coupled to the outrigger jack; and', 'iv) a sensor adapted to measure a property from which a reaction force on the outrigger pad can be determined; and, 'b) a plurality of outrigger assemblies attached to the crane body, each of the plurality of outrigger assemblies comprising i) a processor;', 'ii) a user input device; and', A) receive a user input through the user input device;', 'B) cause a first outrigger jack to extend relative to the outrigger body;', 'C) receive from a first of said sensors a signal from which a first reaction force acting on a first of said outrigger pads can be determined; and', 'D) determine a first outrigger pad status for the first outrigger pad., 'iii) a computer readable storage memory having instructions stored thereon, that, when executed by the processor, cause the crane control system to perform a setup function including], 'c) a crane control system communicatively coupled to each of the sensors of the plurality of outrigger assemblies, the crane control system comprising2. The crane of wherein determining a first outrigger pad status comprises comparing ...
