Crane Data                    
Select design code   =      
No of crane in the same aisle   =              
No of wheel on one side of bridge =              
                   
Crane rated capacity Wrc = [US Ton] = 40.0 [kips]    
Bridge weight Wbr = [kips] 29.6 kips = 25945 [kg]    
Trolley + hoist weight Wth = [kips] 3.6 kips = 4808 [kg]    
Bridge wheel spacing d1 = [ ft ]            
Max. static wheel load by vendor Pmax-v = [kips]            
Crane bridge span Sr = [ ft ]            
Min. hook approach left  SL = [ ft ] 3.1 ft          
  right  SR = [ ft ] 3.1 ft          
Runway CL to col CL distance left  eL = [ ft ] 1.6 ft          
  right  eR = [ ft ] 1.6 ft          
Crane runway beam span L1 = [ ft ]            
Crane column CL to CL distance Sr + 2e = [ ft ]            
Runway Beam    
Runway beam section type   =  
W and C comb section size   =          
W27x84 + C15x33.9
Weight : 117.9 lb/ft

All section dimensions are in inches          
Crane running type   =            
Crane rail size   = Ucr = 60 [lbs/yd]    
            = 0.020 [kip/ft]    
Rail base width Bw = 4.250 [in] Rail height Ht = 4.250 [in]    
W section yield strength fwy = [ksi]            
Cap channel or plate yield strength fcy = [ksi]            
CMAA crane service class   =    moderate service  
Vertical load impact factor   =              
Crane side thrust load option   =            
Crane side thrust load can be calculated using one of the following 4 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)    
Option 3 Hs = max of 0.2 (Lifted Load+ Trolley/Hoist Wt)    
        0.1 (Lifted Load+ Entire Crane Wt)    
        0.4 Lifted Load    
Option 4 Hs =    2.0 x Lifted Load as side thrust for stacker crane
