Abstract
A radio frequency identification (RFID) tower crane load locator and sway indicator includes: a plurality of RFID tags at different locations on or around the crane; at least two RFID readers at different locations on the crane; a navigation satellite system (NSS) position receiver; and a load information interface. The RFID readers comprise a range determiner to provide range measurements between each of the RFID readers and each of the RFID tags. The sway determiner is coupled with a hook block of the crane. The NSS position receiver is coupled with the crane and comprises an antenna fixedly coupled with approximately the front of a jib of the crane. The load information interface combines information from range measurements, the sway determiner and the NSS position receiver to generate location and sway information of the load with respect to the crane and provide this information in a user accessible format.
