I-Bars

We have heat straightened hundreds of railroad bridges than have needed the I-bars heat straightened. Loose I-bars can cause many problems in a bridge. Some common results of loose I-bars are: bridges that sway from side to side, floor beam connection angles to crack, rivets breaking or even bolts that have replaced the rivets. We can heat straighten worn pin problems that cause diagonal built up members to pump back and forth. The flame straightening or heat straightening of loose I-bars can solve most of the problems in a bridge. This can all be done under traffic with very minimal disruption to normal traffic. Most swing spans with clearance problems at the rocker can be solved with flame straightening or heat straightening. We have raised the ends of swing spans a s much as 3 inches on both ends, even removed 50,000 lbs. of counter weight off of one end of a bridge and made it balance correctly with the added counter weight.
