Side Thrust Loads
Side Thrust Loads
(OP)
Curious how others handle side thrust loads from cranes.
do you take your side thrust loads to both runway girders or do you take all the side thrust to one side only?

RE: Side Thrust Loads
I have always taken side thrust to each side. It may be a bit conservative, but the bridge is not rigidly connected to opposing rails, so there could be a little play.

I have done it both ways and was curious what others do.
With magnet/scrap cranes I usually put the entire side thrust to one side.
RE: Side Thrust Loads
This would be consistent with the method used by JLNJ.

RE: Side Thrust Loads
It is written in table 2.1 about "Crane Vertical Load, Side Thrust and Tractive Force as Pecentages of Respective Load" that the Total Side Thrust (two sides) is Greatest of :
40% of Lifted Load,
20% of Combined Weight of Lifted Load and Trolley,
or 10% of Combined Weight of Lifted Load and Crane.
I'm confused about the 40% of Lifted load part since it is very large. Is there any special condition to apply this part or should I go with 20% of Combined Weight?
Thank you for your help.
