Description of Driving Event:
Replacement of the upper floating beam forward roller support shaft was in progress to eliminate a stress corrosion concern. The 5-ton bridge crane and a sling were being used to lift the Pad B PGHM side 2 upper floating beam Z bar off of the Z roller when a small block with two 5/8" bolts apparently sheared, allowing Z Bar to travel up, contacting a portion of the upper floating beam causing the web strap to be cut.
