Abstract

A method of transferring a load is disclosed. The method includes the steps of enabling synchronization of first and second hoists and first and second trolleys and choosing a hoist function or a trolley function. The first and second hoists are a first mover and second mover, if the hoist function is selected. The first and second trolleys are the first and second movers, if the trolley function is selected. The method includes the steps of commanding one of the first mover and second mover to be the master and the other to be the slave and actuating a master control associated with the master. The method further includes the step of outputting signals to the first and second actuators such that the master and the slave are moved in a direction indicated by the master control.
