Abstract
A lifting device sensor unit is disclosed. In one embodiment, the sensor unit comprises a housing configured to removably couple about a load line of a lifting device. A first global navigation satellite system (GNSS) receiver is coupled with the housing and is configured for determining a sensor unit position in three dimensions. A load monitor is coupled with the housing and is configured for monitoring a load coupled with the load line, including monitoring a load position and a load orientation of the load. A wireless transceiver is coupled with the housing and is configured for wirelessly providing information including the load position, the load orientation, and the sensor unit position, to a display unit located apart from the sensor unit.
