Please use the local standard like

Indian Standard IS: 3177 or

ISO 8686-1 or

Australian Standard AS 2550.3 or

"CMAA 70-00 Specifications for Top Running Bridge and Gantry Type Multiple Girder Electric Overhead Traveling Cranes " which will help you in designing all the system of the overhead crane.

All formulas are available in these standard. This is required as you will be required to take statuatory approval.

Hope this is helpful

In the UK, BS466 is the standard. Make sure you allow for dynamic loadings, and try to design out as many shear forces as possible!

PS: I work for a crane manufacturing firm!
