= 0.29 [kN/m]

Rail base width Bw= 108 [mm] Rail height Ht= 108 [mm]

W section yield strength fwy= 413.7 [MPa]

Cap channel or plate yield strength fcy= 413.7 [MPa]

CMAA crane service class = Class C moderate service

Vertical load impact factor = 25% Crane side thrust load option = Option 1 Crane side thrust load can be calculated using one of the following 3 options

Option 1 Hs = 0.2 (Lifted Load+ Trolley/Hoist Wt)

Option 2 Hs = max of 0.2 (Lifted Load+ Trolley/Hoist Wt)

0.1 (Lifted Load+ Entire Crane Wt)
