Koffler Motor Testing

Removing the Rotor From a 120,000 lb Generator
(2 min 20 sec)

The weight of this 60 ton generator delivered to KOFFLER for repair and maintenance required a 9 axle truck trailer because it was so heavy. The tail-end of the trailer required a separate driver. Unloading the generator required the removal of the rotor from the stator while the generator was still on the truck. To accomplish this two cranes were carefully coordinated by a team of experts. I watched all of this in amazement as I filmed the event.
