A system for monitoring loading of equipment includes a transmitter assembly mounted to the equipment and a central server. The transmitter assembly has a strain gauge secured to the equipment, an on-board controller and a battery. The central server is in communication with the on-board controller. The central server is configured to receive collected loading data from the transmitter assembly. The on-board controller is configured to operate the transmitter assembly in a load monitoring power mode and a deep sleep mode. The on-board controller is configured to operate at a sleep interval when a load measured by the strain gauge is less than ten percent of a rated working load of the equipment and at an active interval when the load measured by the strain gauge is greater than ten percent of the rated working load. The sleep interval is less than the active interval.
