A system for monitoring the operation of a boom is disclosed. The boom has at least one boom section, with each boom section being supported by an actuator assembly such that a load supported by a particular actuator assembly is representative of operation of a corresponding boom section and of a total load experienced by that boom section. A first parameter is sensed, the first parameter being indicative of a load supporte d by a first actuator assembly. It is determined from the sensed first parameter when a total load supported by the first actuator assembly exceeds a predetermined value. Information, indicative of one or more occurrences of total loads exceeding the predetermined value, is stored. Based upon the stored information, an output is provided which is indicati ve of a cause of boom failure.
