I'm trying to figure out how the lateral crane load gets divided out amongst the bridge crane wheels. I've seen two different examples do it two different ways. The crane system I have has 4 total wheels (two on each side). The example in the AISC Design Guide 7 (on page 58) divides by 4, but you don't really know how many wheels they have. So I guess what I'm asking is if you divide the lateral force by the total number of wheels, or just the number of wheels on one side. Thank you for the help.
