Material handling system including dual track assembly and method of operating same

A method of operating a material handling system, comprising:

• providing a manufacturing module including a pair of end frames supporting at least one central beam defining a mid-frame that suspends a pair of parallel composite beams, wherein one of the composite beams defines a portion of a first track assembly, and the other of said composite beams defines a portion of a second track assembly, the manufacturing module further including a pair of first and second independent drive systems, and a control system including a microprocessor in communication with each of the first and second independent drive systems for coordinating movement of a forward trolley and a trailing trolley supported concurrently on the pair of composite beams for traveling along the first and second track assemblies;
• transporting an article along the material handling system, at least in part, by
• supporting the article on a carrier, the carrier having a first end pivotably supported by the forward trolley and a second end pivotably supported by the trailing trolley;
• issuing a first operation signal from the control system to the first independent drive system;
• moving the forward trolley along the portion of the first track assembly defining a first path in response to the first operation signal;
• issuing a second operation signal from the control system to the second independent drive system;
• and
• moving the trailing trolley along the portion of the second track assembly defining a second path in response to the second operation signal.
