Straightness of Monorail Beam
Straightness of Monorail Beam
(OP)
We have a monorail beam (S15x42.9) which has some local deformation of the bottom flange. The trolley has four wheels but is only driven by two of these geared wheels. The deformation is only about 1/8" (vertical); but it is enough that the trolly drive wheels can lose contact with the bottom flange of monorail, and therefore trolley is stuck in place.
Anyone have any experience with straightening of this type? AISC Steel Construction Manual allows heating of normal steel section to 1200F to allow straightening, not sure if crane rails are different. Broused thru CMAA-70 and didn't seen any mention.

The bent part in rails appears to be a fatigue/wear issue. The deformation is in the area of most use, a specific location which it often services one paticular piece of equipment.
