Nuclear refueling platform drive system

Nuclear refueling platform drive system

A drive system for propelling first and second drive trucks (18,20) of a bridge (12) includes a first motor (46) and transmission (32) for driving the first truck (18), an independent second motor (46) and transmission (32) for driving the second truck (20) and a controller (40) for coordinating the...

Zusammenfassung:A drive system for propelling first and second drive trucks (18,20) of a bridge (12) includes a first motor (46) and transmission (32) for driving the first truck (18), an independent second motor (46) and transmission (32) for driving the second truck (20) and a controller (40) for coordinating the first (46) and second motors (46) for maintaining differential transverse travel between the first and second drive trucks (18,20) to less than a predetermined maximum. A first closed-loop (82) controls velocity of the first drive truck (18), a second closed-loop (82) controls velocity of the second drive truck (20), and an auxiliary closed-loop (90) senses a difference in travel of the first and second drive trucks (18,20) and adjusts performance of at least one of the first and second closed-loops (82, 82).
