ABSTRACT:
A drive system for propelling first and second drive trucks of a bridge includes a first motor and transmission for driving the first truck, an independent second motor and transmission for driving the second truck and a controller for coordinating the first and second motors for maintaining differential transverse travel between the first and second drive trucks to less than a predetermined maximum. A first closed-loop controls velocity of the first drive truck, a second closed-loop controls velocity of the second drive truck, and an auxiliary closed-loop senses a difference in travel of the first and second drive trucks and adjusts performance of at least one of the first and second closed-loops.
