Large components, repaired and back in service.

From shafts and gearboxes to heavy weldments, we machine, rebuild and inspect power generation components in one 250,000 sq ft facility, with 22 overhead cranes rated up to 100,000 lb.

CBM was the outfit that straightened out the Drum Drive Base over a weekend last fall. I felt that they treated us fair on cost and did not overcharge us even though we were in a bind.
