First Claim
1. A crane control system for controlling a plurality of cranes each crane having at least two motion axes, the crane control system comprising:
- a master controller unit;
a computer readable storage for storing a plurality of tokens, each token from the plurality of tokens a respective crane from the plurality of cranes; and
a processing unit responsive to inputs by an operator of the master controller unit to send commands to individual cranes from the plurality of cranes, the processing unit being configured to associate the commands with respective tokens to control the cranes associated with the tokens;
wherein the master controller unit is configured to;
operate a first motion axis of a first crane in unison with a first motion axis of a second crane; and
at the same time operate a second motion axis of the first crane independently from a second motion axis of the second crane.

Abstract
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 inputable 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.
