Claim Text:
1. A system for synchronization, the system comprising: a transport device having a first hoist and a second hoist and a first trolley and a second trolley, wherein the first hoist is connected to the first trolley and the second hoist is connected to the second trolley; a first hoist actuator connected to the first hoist and a second hoist actuator connected to the second hoist; a first trolley actuator connected to the first trolley and a second trolley actuator connected to the second trolley; a program logic controller, wherein the program logic controller includes a synchronization module for synchronizing movement of the first and second hoists and the first and second trolleys; and a master control connected to one of the first hoist and the first trolley, wherein the first hoist is a master and the first hoist actuator is a master actuator and the second hoist is a slave and the second hoist actuator is a slave actuator, if operational control of the first and second hoists is selected; wherein the first trolley is the master and the first trolley actuator is the master actuator and the second trolley is the slave and the second trolley actuator is the slave actuator, if operational control of the first and second trolleys is selected; wherein the master control sends a signal to move the master via the master actuator and move the slave via the slave actuator such that the slave moves at substantially the same rate as the master.
