Bio-wall interferences surrounding a steam generator required the two trunnion lifting assemblies to be mounted at a different location. A total quantity of (40) 1-1/2” (38mm) – 8UN tapped holes were needed for bolting each trunnion lifting assembly at the new opposing sides of the generator.
Wachs Solution:
Engineered Solutions custom designed and built a trunnion drilling machine from a specially modified Multi-Axial PowerDrill, outfitted with a 360 degree swivel platform. This platform was attached to a precision ground steel template fixture which housed guide bushings to accurately reproduce true “bolt hole” locations.
Specifications:
Drive Type: Hydraulic
