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.

ELECTRONIC ROUNDSLING INSPECTION, LOAD MONITORING AND WARNING SYSTEM
An electronic overload inspection and warning system for a roundsling having a strand positioned within a plurality of core strands and a cover. The system includes a wireless sensor system mountable to the roundsling. The wireless sensor system includes at least one strain gauge electrically connected with a wireless transmitter. The strain gauge measures strain on the strand. The system also includes a wireless base station and a carrier element. The wireless base station includes a wireless receiver configuredto wirelessly communicate with multiple deployed wireless sensor systems. The carrier element is secured to the strand. The strain gauge is secured to the carrier element.
