摘要： A crane control system for controlling a plurality of cranes is provided. The crane control system in some embodiments includes a master controller unit, at least one computer readable memory for storing a plurality of tokens, each token from the plurality of tokens associated with a respective crane from the plurality of cranes, and a processing unit responsive to commands inputtable by an operator of the master controller unit to send the commands to individual cranes from the plurality of cranes, wherein the processing unit associates the commands with respective tokens to control the cranes associated with those tokens. The crane control system in some embodiments also includes a processing unit that is responsive to a signal indicative of a synchronization loss to issue a command to bring the plurality of cranes into a safe condition, such as an emergency stop, or a corrective action
