Crane Rail Clip Spacing
Crane Rail Clip Spacing
(OP)
Is there a maximum spacing for crane rail clips? The 1989 version of the AISC ASD manual suggests a spacing of 3', but it is not a hard number. My clips are 9" long and I want to space them 4.5' on center. Strucuturally the crane rail is okay with the lateral loads applied, I am mostly curious if there is an industry rule of thumb or code that limits the spacing of the rail clips. The crane is a large overhead crane that runs on two rails.
Thanks,

Thanks again, and let me know if you have any other thoughts. Some other poeple have suggested keeping it to 3 feet or less, but there are considerable savings for my partiular case if I can make few 3/4" welds 18" long. I am mostly worried about the capacity of the rail not the clips.

Great minds think alike, I have an identical post on the strucutral board, I was trying to cover all the bases. Seems like most are in agreement that industry practice is to space them closer, but I think we are going to do some in depth analysis and try to space them further apart. So far I haven't learned of anything that will bar me from spacing them further apart.
