rail eccentricity
 

rail eccentricity
how can i to evaluate the effects of rail eccentricity in a crane girder? i need informations about a method of australian standard a5 1418.18 to evaluate torsional resistance of the rail and crane girder flange.
find a job or post a job opening
look into crane design manual to find tollerance on rail mislignment and double it.
by as1418.18 appendix c the torsion can be replaced by 'pairs of lateral forces acting at the top & bot. flanges'.
