RE: Crane rails crossing expansion joints

[Subject Prev][Subject Next][Thread Prev][Thread Next]
There's been a lot of discussion of adopting other engineers typical details
lately.  This is an example of a typical detail used by engineers doing
industrial design that is almost identical from firm to firm.  It's been
around probably for a 100 years.  Basically provide a sharply skewed joint
in the rail and reinforce the rail head with web filler plates.  Maybe
someone can share an example of this typical detail with you.
