RE: Crane Runway Bracing Vibration

Look forward to hearing about it.

This hasn't come up for me before, but we sure are seeing a lot of cranes 
going in.

Bill, Gary,

         Actually, if one of the end trucks (or, for that matter, one of the 
 wheels) is misalligned the problem won't go away until the misallignment 
is corrected.  No matter how much structure Gary builds the "crabing" or 
"racking" will not go away and may, in fact, result in some problem that is 
worse that vibrating bracing.

         I still have a good relationship with my former client who sell, 
install, and maintain, all manner of cranes.  I will pick their brains and 
see if I can come up with some more ideas.

         Thanks for reminding me of the misallignment problem.
