[Subject Prev][Subject Next][Thread Prev][Thread Next]
If possible, I would avoid using the expansion joint, especially in a
seismically active area.

	Does anyone have any experience with overhead cranes in industrial
facilities 
	where the runway beams & rails cross a building expansion joint? How
do you 
	provide continuity of the rail, yet allow the joint to open and
close? Low 
	friction clips?
