4.1 Required input data

As explained in the preceding paragraphs, the following information is required to justify/verify the cross-sections of monorail beams:

• lowering of cart loads (Q _c , Q _h or Q _c + Q _h ) per roller or pair of rollers;

• dynamic coefficient(s) to be applied ;

• whether or not it is necessary to consider a horizontal transverse effort and, if so, the value(s) to be considered;

• the distance between rollers in the direction of the beam (noted...
