Allowable Crane Deflection (Picked up by Cantilevered Beam)
Allowable Crane Deflection (Picked up by Cantilevered Beam)
(OP)
Hi All,
I have a Crane Runway beam that is picked up at the end of the runway by a transverse beam. The transverse beam is actually cantilevered and I am wondering what the thought is on the allowable deflection of the cantilever. Does say L/600 still apply? or is there another process to go through?
Any help is much appreciated.
Regards,

The essential of the check is to make sure the slope of the crane runway is not too steep and not causes trolley travelling troubles.
RE: Allowable Crane Deflection (Picked up by Cantilevered Beam)
If a typical runway beam deflects L/600, the end slope is 1/200 for a simple span with concentrated load at midspan. If the end support of a runway beam deflects L/600 when the load is at the end, the maximum slope of the runway beam is 1/600.
If the object is to provide a maximum slope of 1/200 for the crane to climb, you could permit a deflection of L/200 on the end support; however it might be more prudent to permit a deflection of L/300 or L/400.
